Changelog¶
Attention
Major and minor releases of pip also include changes listed within prior beta releases.
Not yet released (2024-09-16)¶
Deprecations and Removals¶
Deprecate wheel filenames that are not compliant with PEP 440. (#12918)
Features¶
Detect recursively referencing requirements files and help users identify the source. (#12653)
Bug Fixes¶
If the user’s pip.conf includes a target directory setting, attempting to install a package in editable mode or from source results in a fatal error during the installation of setuptools.
The following assertion triggers: assert not (home and prefix), “home={} prefix={}”.format(home, prefix)
To avoid this issue when building a package, the target setting should be ignored. This can be achieved by passing an empty target when installing dependencies in the BuildEnvironment class. (#8438)
Vendored Libraries¶
Upgrade urllib3 to 1.26.20
24.2 (2024-07-28)¶
Deprecations and Removals¶
Features¶
Check unsupported packages for the current platform. (#11054)
Use system certificates and certifi certificates to verify HTTPS connections on Python 3.10+. Python 3.9 and earlier only use certifi.
To revert to previous behaviour, pass the flag
--use-deprecated=legacy-certs
. (#11647)Improve discovery performance of installed packages when the
importlib.metadata
backend is used to load distribution metadata (used by default under Python 3.11+). (#12656)Improve performance when the same requirement string appears many times during resolution, by consistently caching the parsed requirement string. (#12663)
Minor performance improvement of finding applicable package candidates by not repeatedly calculating their versions (#12664)
Disable pip’s self version check when invoking a pip subprocess to install PEP 517 build requirements. (#12683)
Improve dependency resolution performance by caching platform compatibility tags during wheel cache lookup. (#12712)
wheel
is no longer explicitly listed as a build dependency ofpip
.setuptools
injects this dependency in theget_requires_for_build_wheel()
hook and no longer needs it on newer versions. (#12728)Ignore
--require-virtualenv
forpip check
andpip freeze
(#12842)Improve package download and install performance.
Increase chunk sizes when downloading (256 kB, up from 10 kB) and reading files (1 MB, up from 8 kB). This reduces the frequency of updates to pip’s progress bar. (#12810)
Improve pip install performance.
Files are now extracted in 1MB blocks, or in one block matching the file size for smaller files. A decompressor is no longer instantiated when extracting 0 bytes files, it is not necessary because there is no data to decompress. (#12803)
Bug Fixes¶
Set
no_color
to globalrich.Console
instance. (#11045)Fix resolution to respect
--python-version
when checkingRequires-Python
. (#12216)Perform hash comparisons in a case-insensitive manner. (#12680)
Avoid
dlopen
failure for glibc detection in musl builds (#12716)Avoid keyring logging crashes when pip is run in verbose mode. (#12751)
Fix finding hardlink targets in tar files with an ignored top-level directory. (#12781)
Improve pip install performance by only creating required parent directories once, instead of before extracting every file in the wheel. (#12782)
Improve pip install performance by calculating installed packages printout in linear time instead of quadratic time. (#12791)

Deprecations and Removals¶
Drop support for EOL Python 3.7. (#11934)
Remove support for legacy versions and dependency specifiers.
Packages with non standard-compliant versions or dependency specifiers are now ignored by the resolver. Already installed packages with non standard-compliant versions or dependency specifiers must be uninstalled before upgrading them. (#12063)
Features¶
Improve performance of resolution of large dependency trees, with more caching. (#12453)
Further improve resolution performance of large dependency trees, by caching hash calculations. (#12657)
Reduce startup time of commands (e.g. show, freeze) that do not access the network by 15-30%. (#4768)

24.0 (2024-02-03)¶
Features¶
Retry on HTTP status code 502 (#11843)
Automatically use the setuptools PEP 517 build backend when
--config-settings
is used for projects withoutpyproject.toml
. (#11915)Make pip freeze and pip uninstall of legacy editable installs of packages whose name contains
_
compatible withsetuptools>=69.0.3
. (#12477)Support per requirement
--config-settings
for editable installs. (#12480)
Bug Fixes¶
Optimized usage of
--find-links=<path-to-dir>
, by only scanning the relevant directory once, only considering file names that are valid wheel or sdist names, and only considering files in the directory that are related to the install. (#12327)Removed
wheel
from the[build-system].requires
list fallback that is used whenpyproject.toml
is absent. (#12449)
Vendored Libraries¶

Fix outdated pip install argument description in documentation. (#12417)
Replace some links to PEPs with links to the canonical specifications on the Python Packaging User Guide (#12434)
Updated the
pyproject.toml
document to stop suggesting to depend onwheel
as a build dependency directly. (#12449)Update supported interpreters in development docs (#12475)
Process¶
Most project metadata is now defined statically via pip’s
pyproject.toml
file.
23.3.2 (2023-12-17)¶
Bug Fixes¶
23.3.1 (2023-10-21)¶
Bug Fixes¶
23.3 (2023-10-15)¶
Process¶
Added reference to vulnerability reporting guidelines to pip’s security policy.
Deprecations and Removals¶
Drop a fallback to using SecureTransport on macOS. It was useful when pip detected OpenSSL older than 1.0.1, but the current pip does not support any Python version supporting such old OpenSSL versions. (#12175)
Features¶
Improve extras resolution for multiple constraints on same base package. (#11924)
Improve use of datastructures to make candidate selection 1.6x faster. (#12204)
Allow
pip install --dry-run
to use platform and ABI overriding options. (#12215)Add
is_yanked
boolean entry to the installation report (--report
) to indicate whether the requirement was yanked from the index, but was still selected by pip conform to PEP 592. (#12224)
Bug Fixes¶
Ignore errors in temporary directory cleanup (show a warning instead). (#11394)
Normalize extras according to PEP 685 from package metadata in the resolver for comparison. This ensures extras are correctly compared and merged as long as the package providing the extra(s) is built with values normalized according to the standard. Note, however, that this does not solve cases where the package itself contains unnormalized extra values in the metadata. (#11649)
Prevent downloading sdists twice when PEP 658 metadata is present. (#11847)
Include all requested extras in the install report (
--report
). (#11924)Removed uses of
datetime.datetime.utcnow
from non-vendored code. (#12005)Consistently report whether a dependency comes from an extra. (#12095)
Fix completion script for zsh (#12166)
Fix improper handling of the new onexc argument of
shutil.rmtree()
in Python 3.12. (#12187)Filter out yanked links from the available versions error message: “(from versions: 1.0, 2.0, 3.0)” will not contain yanked versions conform PEP 592. The yanked versions (if any) will be mentioned in a separate error message. (#12225)
Fix crash when the git version number contains something else than digits and dots. (#12280)
Use
-r=...
instead of-r ...
to specify references with Mercurial. (#12306)Redact password from URLs in some additional places. (#12350)
pip uses less memory when caching large packages. As a result, there is a new on-disk cache format stored in a new directory ($PIP_CACHE_DIR/http-v2). (#2984)
Vendored Libraries¶
Upgrade certifi to 2023.7.22
Add truststore 0.8.0
Upgrade urllib3 to 1.26.17
Improved Documentation¶
23.2.1 (2023-07-22)¶
Bug Fixes¶
23.2 (2023-07-15)¶
Process¶
Deprecate support for eggs for Python 3.11 or later, when the new
importlib.metadata
backend is used to load distribution metadata. This only affects the egg distribution format (with the.egg
extension); distributions using the.egg-info
metadata format (but are not actually eggs) are not affected. For more information about eggs, see relevant section in the setuptools documentation.
Deprecations and Removals¶
Deprecate legacy version and version specifiers that don’t conform to the specification. (#12063)
freeze
no longer excludes thesetuptools
,distribute
, andwheel
from the output when running on Python 3.12 or later, where they are not included in a virtual environment by default. Use--exclude
if you wish to exclude any of these packages. (#4256)
Features¶
make rejection messages slightly different between 1 and 8, so the user can make the difference. (#12040)
Bug Fixes¶
Fix
pip completion --zsh
. (#11417)Prevent downloading files twice when PEP 658 metadata is present (#11847)
Add permission check before configuration (#11920)
Fix deprecation warnings in Python 3.12 for usage of shutil.rmtree (#11957)
Ignore invalid or unreadable
origin.json
files in the cache of locally built wheels. (#11985)Fix installation of packages with PEP 658 metadata using non-canonicalized names (#12038)
Correctly parse
dist-info-metadata
values from JSON-format index data. (#12042)Fail with an error if the
--python
option is specified after the subcommand name. (#12067)Fix slowness when using
importlib.metadata
(the default way for pip to read metadata in Python 3.11+) and there is a large overlap between already installed and to-be-installed packages. (#12079)Pass the
-r
flag to mercurial to be explicit that a revision is passed and protect againsthg
options injection as part of VCS URLs. Users that do not have control on VCS URLs passed to pip are advised to upgrade. (#12119)

23.1.2 (2023-04-26)¶
Vendored Libraries¶
Upgrade setuptools to 67.7.2
23.1.1 (2023-04-22)¶
Bug Fixes¶
Vendored Libraries¶
Revert pkg_resources (via setuptools) back to 65.6.3
Improved Documentation¶
Update documentation to reflect the new behavior of using the cache of locally built wheels in hash-checking mode. (#11967)
23.1 (2023-04-15)¶
Deprecations and Removals¶
Remove support for the deprecated
--install-options
. (#11358)--no-binary
does not implysetup.py install
anymore. Instead a wheel will be built locally and installed. (#11451)--no-binary
does not disable the cache of locally built wheels anymore. It only means “don’t download wheels”. (#11453)Deprecate
--build-option
and--global-option
. Users are invited to switch to--config-settings
. (#11859)Using
--config-settings
with projects that don’t have apyproject.toml
now prints a deprecation warning. In the future the presence of config settings will automatically enable the default build backend for legacy projects and pass the settings to it. (#11915)Remove
setup.py install
fallback when building a wheel failed for projects withoutpyproject.toml
. (#8368)When the
wheel
package is not installed, pip now uses the default build backend instead ofsetup.py install
andsetup.py develop
for project withoutpyproject.toml
. (#8559)
Features¶
Specify egg-link location in assertion message when it does not match installed location to provide better error message for debugging. (#10476)
Present conflict information during installation after each choice that is rejected (pass
-vv
topip install
to show it) (#10937)Display dependency chain on each Collecting/Processing log line. (#11169)
Support a per-requirement
--config-settings
option in requirements files. (#11325)The
--config-settings
/-C
option now supports using the same key multiple times. When the same key is specified multiple times, all values are passed to the build backend as a list, as opposed to the previous behavior, where pip would only pass the last value if the same key was used multiple times. (#11681)Add
-C
as a short version of the--config-settings
option. (#11786)Reduce the number of resolver rounds, since backjumping makes the resolver more efficient in finding solutions. This also makes pathological cases fail quicker. (#11908)
Warn if
--hash
is used on a line without requirement in a requirements file. (#11935)Stop propagating CLI
--config-settings
to the build dependencies. They already did not propagate to requirements provided in requirement files. To pass the same config settings to several requirements, users should provide the requirements as CLI arguments. (#11941)Support wheel cache when using
--require-hashes
. (#5037)Add
--keyring-provider
flag. See the Authentication page in the documentation for more info. (#8719)In the case of virtual environments, configuration files are now also included from the base installation. (#9752)
Bug Fixes¶
Fix grammar by changing “A new release of pip available:” to “A new release of pip is available:” in the notice used for indicating that. (#11529)
Normalize paths before checking if installed scripts are on PATH. (#11719)
Correct the way to decide if keyring is available. (#11774)
More consistent resolution backtracking by removing legacy hack related to setuptools resolution (#11837)
Include
AUTHORS.txt
in pip’s wheels. (#11882)The
uninstall
andinstall --force-reinstall
commands no longer callnormalize_path()
repeatedly on the same paths. Instead, these results are cached for the duration of an uninstall operation, resulting in improved performance, particularly on Windows. (#11889)Fix and improve the parsing of hashes embedded in URL fragments. (#11936)
When package A depends on package B provided as a direct URL dependency including a hash embedded in the link, the
--require-hashes
option did not warn when user supplied hashes were missing for package B. (#11938)Correctly report
requested_extras
in the installation report when extras are specified for a local directory installation. (#11946)When installing an archive from a direct URL or local file, populate
download_info.info.hashes
in the installation report, in addition to the legacydownload_info.info.hash
key. (#11948)
Vendored Libraries¶

Improved Documentation¶
Cross-reference the
--python
flag from the--prefix
flag, and mention limitations of--prefix
regarding script installation. (#11775)Add SECURITY.md to make the policy official. (#11809)
Add username to Git over SSH example. (#11838)
Quote extras in the pip install docs to guard shells with default glob qualifiers, like zsh. (#11842)
Make it clear that requirements/constraints file can be a URL (#11954)
23.0.1 (2023-02-17)¶
Features¶
Bug Fixes¶
23.0 (2023-01-30)¶
Features¶
Change the hashes in the installation report to be a mapping. Emit the
archive_info.hashes
dictionary indirect_url.json
. (#11312)Implement logic to read the
EXTERNALLY-MANAGED
file as specified in PEP 668. This allows a downstream Python distributor to prevent users from using pip to modify the externally managed environment. (#11381)Enable the use of
keyring
found onPATH
. This allowskeyring
installed usingpipx
to be used bypip
. (#11589)The inspect and installation report formats are now declared stable, and their version has been bumped from
0
to1
. (#11757)
Bug Fixes¶
Wheel cache behavior is restored to match previous versions, allowing the cache to find existing entries. (#11527)
Use the “venv” scheme if available to obtain prefixed lib paths. (#11598)
Deprecated a historical ambiguity in how
egg
fragments in URL-style requirements are formatted and handled.egg
fragments that do not look like PEP 508 names now produce a deprecation warning. (#11617)Fix scripts path in isolated build environment on Debian. (#11623)
Make

Bug Fixes¶
Fix entry point generation of
pip.X
,pipX.Y
, andeasy_install-X.Y
to correctly account for multi-digit Python version segments (e.g. the “11” part of 3.11). (#11547)
22.3 (2022-10-15)¶
Deprecations and Removals¶
Deprecate
--install-options
which forces pip to use the deprecatedinstall
command ofsetuptools
. (#11358)Deprecate installation with ‘setup.py install’ when no-binary is enabled for source distributions without ‘pyproject.toml’. (#11452)
Deprecate
`--no-binary
disabling the wheel cache. (#11454)Remove
--use-feature=2020-resolver
opt-in flag. This was supposed to be removed in 21.0, but missed during that release cycle. (#11493)Deprecate installation with ‘setup.py install’ when the ‘wheel’ package is absent for source distributions without ‘pyproject.toml’. (#8559)
Remove the ability to use
pip list --outdated
in combination with--format=freeze
. (#9789)
Features¶
Use
shell=True
for opening the editor withpip config edit
. (#10716)Use the
data-dist-info-metadata
attribute from PEP 658 to resolve distribution metadata without downloading the dist yet. (#11111)Add an option to run the test suite with pip built as a zipapp. (#11250)
Add a
--python
option to allow pip to manage Python environments other than the one pip is installed in. (#11320)Document the new (experimental) zipapp distribution of pip. (#11459)
Use the much faster ‘bzr co --lightweight’ to obtain a copy of a Bazaar tree. (#5444)
Bug Fixes¶

22.2.2 (2022-08-03)¶
Bug Fixes¶
22.2.1 (2022-07-27)¶
Bug Fixes¶
Send the pip upgrade prompt to stderr. (#11282)
Ensure that things work correctly in environments where setuptools-injected
distutils
is available by default. This is done by cooperating with setuptools’ injection logic to ensure that pip uses thedistutils
from the Python standard library instead. (#11298)Clarify that
pip cache
’s wheels-related output is about locally built wheels only. (#11300)
22.2 (2022-07-21)¶
Deprecations and Removals¶
Features¶
Add support to use truststore as an alternative SSL certificate verification backend. The backend can be enabled on Python 3.10 and later by installing
truststore
into the environment, and adding the--use-feature=truststore
flag to various pip commands.truststore
differs from the current default verification backend (provided bycertifi
) in it uses the operating system’s trust store, which can be better controlled and augmented to better support non-standard certificates. Depending on feedback, pip may switch to this as the default certificate verification backend in the future. (#11082)Add
--dry-run
option topip install
, to let it print what it would install but not actually change anything in the target environment. (#11096)Record in wheel cache entries the URL of the original artifact that was downloaded to build the cached wheels. The record is named
origin.json
and uses the PEP 610 Direct URL format. (#11137)pip’s deprecation warnings now subclass the built-in
DeprecationWarning
, and can be suppressed by running the Python interpreter with-W ignore::DeprecationWarning
. (#11225)Add
pip inspect
command to obtain the list of installed distributions and other information about the Python environment, in JSON format. (#11245)Significantly speed up isolated environment creation, by using the same sources for pip instead of creating a standalone installation for each environment. (#11257)
Add an experimental
--report
option to the install command to generate a JSON report of what was installed. In combination with--dry-run
and--ignore-installed
it can be used to resolve the requirements. (#53)
Bug Fixes¶
Fix
pip install --pre
for packages with pre-release build dependencies defined both inpyproject.toml
’sbuild-system.requires
andsetup.py
’ssetup_requires
. (#10222)When pip rewrites the shebang line in a script during wheel installation, update the hash and size in the corresponding
RECORD
file entry. (#10744)Do not consider a
.dist-info
directory found inside a wheel-like zip file as metadata for an installed distribution. A package in a wheel is (by definition) not installed, and is not guaranteed to work due to how a wheel is structured. (#11217)Use
importlib.resources
to read thevendor.txt
file inpip debug
. This makes the command safe for use from a zipapp. (#11248)Make the
--use-pep517
option of thedownload
command apply not just to the requirements specified on the command line, but to their dependencies, as well. (#9523)
Process¶
Remove reliance on the stdlib cgi module, which is deprecated in Python 3.11.

22.1.2 (2022-05-31)¶
Bug Fixes¶
22.1.1 (2022-05-20)¶
Bug Fixes¶
Properly filter out optional dependencies (i.e. extras) when checking build environment distributions. (#11112)
Change the build environment dependency checking to be opt-in. (#11116)
Allow using a pre-release version to satisfy a build requirement. This helps manually populated build environments to more accurately detect build-time requirement conflicts. (#11123)
22.1 (2022-05-11)¶
Process¶
Enable the
importlib.metadata
metadata implementation by default on Python 3.11 (or later). The environment variable_PIP_USE_IMPORTLIB_METADATA
can still be used to enable the implementation on 3.10 and earlier, or disable it on 3.11 (by setting it to0
orfalse
).
Bug Fixes¶
22.1b1 (2022-04-30)¶
Process¶
Start migration of distribution metadata implementation from
pkg_resources
toimportlib.metadata
. The new implementation is currently not exposed in any user-facing way, but included in the code base for easier development.
Deprecations and Removals¶
Drop
--use-deprecated=out-of-tree-build
, according to deprecation message. (#11001)
Features¶
Add option to install and uninstall commands to opt-out from running-as-root warning. (#10556)
Include Project-URLs in

output. (#11074)
22.0.4 (2022-03-06)¶
Deprecations and Removals¶
Drop the doctype check, that presented a warning for index pages that use non-compliant HTML 5. (#10903)
Vendored Libraries¶
Downgrade distlib to 0.3.3.
22.0.3 (2022-02-03)¶
Features¶
Print the exception via
rich.traceback
, when running with--debug
. (#10791)
Bug Fixes¶
Only calculate topological installation order, for packages that are going to be installed/upgraded.
This fixes an AssertionError that occurred when determining installation order, for a very specific combination of upgrading-already-installed-package + change of dependencies + fetching some packages from a package index. This combination was especially common in Read the Docs’ builds. (#10851)
Use
html.parser
by default, instead of falling back tohtml5lib
when--use-deprecated=html5lib
is not passed. (#10869)
Improved Documentation¶
Clarify that using per-requirement overrides disables the usage of wheels. (#9674)
22.0.2 (2022-01-30)¶
Deprecations and Removals¶
Instead of failing on index pages that use non-compliant HTML 5, print a deprecation warning and fall back to
html5lib
-based parsing for now. This simplifies the migration for non-compliant index pages, by letting such indexes function with a warning. (#10847)
22.0.1 (2022-01-30)¶
Bug Fixes¶
22.0 (2022-01-29)¶
Process¶
Deprecations and Removals¶
Deprecate alternative progress bar styles, leaving only
on
andoff
as available choices. (#10462)Drop support for Python 3.6. (#10641)
Disable location mismatch warnings on Python versions prior to 3.10.
These warnings were helping identify potential issues as part of the sysconfig -> distutils transition, and we no longer need to rely on reports from older Python versions for information on the transition. (#10840)
Features¶
Changed
PackageFinder
to parse HTML documents using the stdlibhtml.parser.HTMLParser
class instead of thehtml5lib
package.For now, the deprecated
html5lib
code remains and can be used with the--use-deprecated=html5lib
command line option. However, it will be removed in a future pip release. (#10291)Utilise
rich
for presenting pip’s default download progress bar. (#10462)Present a better error message when an invalid wheel file is encountered, providing more context where the invalid wheel file is. (#10535)

. (#10647)Make it possible to deselect tests requiring cryptography package on systems where it cannot be installed. (#10686)
Start using Rich for presenting error messages in a consistent format. (#10703)
Improve presentation of errors from subprocesses. (#10705)
Forward pip’s verbosity configuration to VCS tools to control their output accordingly. (#8819)
Bug Fixes¶
Optimize installation order calculation to improve performance when installing requirements that form a complex dependency graph with a large amount of edges. (#10557)
When a package is requested by the user for upgrade, correctly identify that the extra-ed variant of that same package depended by another user-requested package is requesting the same package, and upgrade it accordingly. (#10613)
Prevent pip from installing yanked releases unless explicitly pinned via the
==
or===
operators. (#10617)Stop backtracking on build failures, by instead surfacing them to the user and aborting immediately. This behaviour provides more immediate feedback when a package cannot be built due to missing build dependencies or platform incompatibility. (#10655)
Silence
Value for <location> does not match
warning caused by an erroneous patch in Slackware-distributed Python 3.9. (#10668)Fix an issue where pip did not consider dependencies with and without extras to be equal (#9644)

21.3.1 (2021-10-22)¶
Bug Fixes¶
Always refuse installing or building projects that have no
pyproject.toml
norsetup.py
. (#10531)Tweak running-as-root detection, to check
os.getuid
if it exists, on Unix-y and non-Linux/non-MacOS machines. (#10565)When installing projects with a
pyproject.toml
in editable mode, and the build backend does not support PEP 660, prepare metadata usingprepare_metadata_for_build_wheel
instead ofsetup.py egg_info
. Also, refuse installing projects that only have asetup.cfg
and nosetup.py
norpyproject.toml
. These restore the pre-21.3 behaviour. (#10573)Restore compatibility of where configuration files are loaded from on MacOS (back to
Library/Application Support/pip
, instead ofPreferences/pip
). (#10585)
Vendored Libraries¶
Upgrade pep517 to 0.12.0
21.3 (2021-10-11)¶
Deprecations and Removals¶
Improve deprecation warning regarding the copying of source trees when installing from a local directory. (#10128)
Suppress location mismatch warnings when pip is invoked from a Python source tree, so
ensurepip
does not emit warnings on CPythonmake install
. (#10270)On Python 3.10 or later, the installation scheme backend has been changed to use
sysconfig
. This is to anticipate the deprecation ofdistutils
in Python 3.10, and its scheduled removal in 3.12. For compatibility considerations, pip installations running on Python 3.9 or lower will continue to usedistutils
. (#10358)Remove the
--build-dir
option and aliases, one last time. (#10485)In-tree builds are now the default.
--use-feature=in-tree-build
is now ignored.--use-deprecated=out-of-tree-build
may be used temporarily to ease the transition. (#10495)Un-deprecate source distribution re-installation behaviour. (#8711)
Features¶
Replace vendored appdirs with platformdirs. (#10202)
Support PEP 610 to detect editable installs in
pip freeze
andpip list
. Thepip list
column output has a newEditable project location
column, and the JSON output has a neweditable_project_location
field. (#10249)pip freeze
will now always fallback to reporting the editable project location when it encounters a VCS error while analyzing an editable requirement. Before, it sometimes reported the requirement as non-editable. (#10410)pip show
now sortsRequires
andRequired-By
alphabetically. (#10422)Do not raise error when there are no files to remove with
pip cache purge/remove
. Instead log a warning and continue (to log that we removed 0 files). (#10459)When backtracking during dependency resolution, prefer the dependencies which are involved in the most recent conflict. This can significantly reduce the amount of backtracking required. (#10479)
Cache requirement objects, to improve performance reducing reparses of requirement strings. (#10550)
Support editable installs for projects that have a
pyproject.toml
and use a build backend that supports PEP 660. (#8212)When a revision is specified in a Git URL, use git’s partial clone feature to speed up source retrieval. (#9086)
Add a
--debug
flag, to enable a mode that doesn’t log errors and propagates them to the top level instead. This is primarily to aid with debugging pip’s crashes. (#9349)If a host is explicitly specified as trusted by the user (via the --trusted-host option), cache HTTP responses from it in addition to HTTPS ones. (#9498)
Bug Fixes¶
Present a better error message, when a
file:
URL is not found. (#10263)Fix the auth credential cache to allow for the case in which the index url contains the username, but the password comes from an external source, such as keyring. (#10269)
Fix double unescape of HTML
data-requires-python
anddata-yanked
attributes. (#10378)New resolver: Fixes depth ordering of packages during resolution, e.g. a dependency 2 levels deep will be ordered before a dependency 3 levels deep. (#10482)
Correctly indent metadata preparation messages in pip output. (#10524)
Vendored Libraries¶
Remove appdirs as a vendored dependency.
Upgrade distlib to 0.3.3
Upgrade distro to 1.6.0
Patch pkg_resources to use platformdirs rather than appdirs.
Add platformdirs as a vendored dependency.
Upgrade progress to 1.6
Upgrade resolvelib to 0.8.0
Upgrade urllib3 to 1.26.7
Improved Documentation¶
Update links of setuptools as setuptools moved these documents. The Simple Repository link now points to PyPUG as that is the canonical place of packaging specification, and setuptools’s
easy_install
is deprecated. (#10430)Create a “Build System Interface” reference section, for documenting how pip interacts with build systems. (#10497)
21.2.4 (2021-08-12)¶
Bug Fixes¶
Fix 3.6.0 compatibility in link comparison logic. (#10280)
21.2.3 (2021-08-06)¶
Bug Fixes¶
Modify the
sysconfig.get_preferred_scheme
function check to be compatible with CPython 3.10’s alphareleases. (#10252)
21.2.2 (2021-07-31)¶
Bug Fixes¶
New resolver: When a package is specified with extras in constraints, and with extras in non-constraint requirements, the resolver now correctly identifies the constraint’s existence and avoids backtracking. (#10233)
21.2.1 (2021-07-25)¶
Process¶
The source distribution re-installation feature removal has been delayed to 21.3.
21.2 (2021-07-24)¶
Process¶
pip freeze
,pip list
, andpip show
no longer normalize underscore (_
) in distribution names to dash (-
). This is a side effect of the migration toimportlib.metadata
, since the underscore-dash normalization behavior is non-standard and specific to setuptools. This should not affect other parts of pip (for example, when feeding thepip freeze
result back intopip install
) since pip internally performs standard PEP 503 normalization independently to setuptools.
Deprecations and Removals¶
Git version parsing is now done with regular expression to prepare for the pending upstream removal of non-PEP-440 version parsing logic. (#10117)
Re-enable the “Value for … does not match” location warnings to field a new round of feedback for the
distutils
-sysconfig
transition. (#10151)Remove deprecated
--find-links
option inpip freeze
(#9069)
Features¶
New resolver: Loosen URL comparison logic when checking for direct URL reference equivalency. The logic includes the following notable characteristics:
The authentication part of the URL is explicitly ignored.
Most of the fragment part, including
egg=
, is explicitly ignored. Onlysubdirectory=
and hash values (e.g.sha256=
) are kept.The query part of the URL is parsed to allow ordering differences. (#10002)
Support TOML v1.0.0 syntax in
pyproject.toml
. (#10034)Added a warning message for errors caused due to Long Paths being disabled on Windows. (#10045)
Change the encoding of log file from default text encoding to UTF-8. (#10071)
Log the resolved commit SHA when installing a package from a Git repository. (#10149)
Add a warning when passing an invalid requirement to
pip uninstall
. (#4958)Add new subcommand
pip index
used to interact with indexes, and implementpip index version
to list available versions of a package. (#7975)When pip is asked to uninstall a project without the dist-info/RECORD file it will no longer traceback with FileNotFoundError, but it will provide a better error message instead, such as:
ERROR: Cannot uninstall foobar 0.1, RECORD file not found. You might be able to recover from this via: 'pip install --force-reinstall --no-deps foobar==0.1'.
When dist-info/INSTALLER is present and contains some useful information, the info is included in the error message instead:
ERROR: Cannot uninstall foobar 0.1, RECORD file not found. Hint: The package was installed by rpm.
(#8954)
Add an additional level of verbosity.
--verbose
(and the shorthand-v
) now contains significantly less output, and users that need complete full debug-level output should pass it twice (--verbose --verbose
or-vv
). (#9450)New resolver: The order of dependencies resolution has been tweaked to traverse the dependency graph in a more breadth-first approach. (#9455)
Make “yes” the default choice in
pip uninstall
’s prompt. (#9686)Add a special error message when users forget the
-r
flag when installing. (#9915)New resolver: A distribution’s
Requires-Python
metadata is now checked before its Python dependencies. This makes the resolver fail quicker when there’s an interpreter version conflict. (#9925)Suppress “not on PATH” warning when
--prefix
is given. (#9931)Include
rustc
version in pip’sUser-Agent
, when the system hasrustc
. (#9987)
Bug Fixes¶
Update vendored six to 1.16.0 and urllib3 to 1.26.5 (#10043)
Correctly allow PEP 517 projects to be detected without warnings in
pip freeze
. (#10080)Strip leading slash from a
file://
URL built from an path with the Windows drive notation. This fixes bugs where thefile://
URL cannot be correctly used as requirement, constraint, or index URLs on Windows. (#10115)New resolver: URL comparison logic now treats
file://localhost/
andfile:///
as equivalent to conform to RFC 8089. (#10162)Prefer credentials from the URL over the previously-obtained credentials from URLs of the same domain, so it is possible to use different credentials on the same index server for different
--extra-index-url
options. (#3931)Fix extraction of files with utf-8 encoded paths from tars. (#7667)
Skip distutils configuration parsing on encoding errors. (#8931)
New resolver: Detect an unnamed requirement is user-specified (by building its metadata for the project name) so it can be correctly ordered in the resolver. (#9204)
Fix pip freeze to output packages installed from git in the correct
git+protocol://git.example.com/MyProject#egg=MyProject
format rather than the old and no longer supportedgit+git@
format. (#9822)Fix warnings about install scheme selection for Python framework builds distributed by Apple’s Command Line Tools. (#9844)
Relax interpreter detection to quelch a location mismatch warning where PyPy is deliberately breaking backwards compatibility. (#9845)
Vendored Libraries¶

Upgrade urllib3 to 1.26.6.
21.1.3 (2021-06-26)¶
Bug Fixes¶
21.1.2 (2021-05-23)¶
Bug Fixes¶
New resolver: Correctly exclude an already installed package if its version is known to be incompatible to stop the dependency resolution process with a clear error message. (#9841)
Allow ZIP to archive files with timestamps earlier than 1980. (#9910)
Emit clearer error message when a project root does not contain either
pyproject.toml
,setup.py
orsetup.cfg
. (#9944)Fix detection of existing standalone pip instance for PEP 517 builds. (#9953)
21.1.1 (2021-04-30)¶
Deprecations and Removals¶
Temporarily set the new “Value for … does not match” location warnings level to DEBUG, to hide them from casual users. This prepares pip 21.1 for CPython inclusion, while pip maintainers digest the first intake of location mismatch issues for the
distutils
-sysconfig
transition. (#9912)
Bug Fixes¶
This change fixes a bug on Python <=3.6.1 with a Typing feature added in 3.6.2 (#9831)
Fix compatibility between distutils and sysconfig when the project name is unknown outside of a virtual environment. (#9838)
Fix Python 3.6 compatibility when a PEP 517 build requirement itself needs to be built in an isolated environment. (#9878)
21.1 (2021-04-24)¶
Process¶
Start installation scheme migration from
distutils
tosysconfig
. A warning is implemented to detect differences between the two implementations to encourage user reports, so we can avoid breakages before they happen.
Features¶
Add the ability for the new resolver to process URL constraints. (#8253)
Add a feature
--use-feature=in-tree-build
to build local projects in-place when installing. This is expected to become the default behavior in pip 21.3; see Installing from local packages for more information. (#9091)Bring back the “(from versions: …)” message, that was shown on resolution failures. (#9139)
Add support for editable installs for project with only setup.cfg files. (#9547)
Improve performance when picking the best file from indexes during
pip install
. (#9748)Warn instead of erroring out when doing a PEP 517 build in presence of
--build-option
. Warn when doing a PEP 517 build in presence of--global-option
. (#9774)
Bug Fixes¶
Fixed
--target
to work with--editable
installs. (#4390)Add a warning, discouraging the usage of pip as root, outside a virtual environment. (#6409)
Ignore
.dist-info
directories if the stem is not a valid Python distribution name, so they don’t show up in e.g.pip freeze
. (#7269)Only query the keyring for URLs that actually trigger error 401. This prevents an unnecessary keyring unlock prompt on every pip install invocation (even with default index URL which is not password protected). (#8090)
Prevent packages already-installed alongside with pip to be injected into an isolated build environment during build-time dependency population. (#8214)
Fix
pip freeze
permission denied error in order to display an understandable error message and offer solutions. (#8418)Correctly uninstall script files (from setuptools’
scripts
argument), when installed with--user
. (#8733)New resolver: When a requirement is requested both via a direct URL (
req @ URL
) and via version specifier with extras (req[extra]
), the resolver will now be able to use the URL to correctly resolve the requirement with extras. (#8785)New resolver: Show relevant entries from user-supplied constraint files in the error message to improve debuggability. (#9300)
Avoid parsing version to make the version check more robust against lousily debundled downstream distributions. (#9348)
--user
is no longer suggested incorrectly when pip fails with a permission error in a virtual environment. (#9409)Fix incorrect reporting on
Requires-Python
conflicts. (#9541)Make wheel compatibility tag preferences more important than the build tag (#9565)
Fix pip to work with warnings converted to errors. (#9779)
SECURITY: Stop splitting on unicode separators in git references, which could be maliciously used to install a different revision on the repository. (#9827)

Fix error when an existing incompatibility is unable to be applied to a backtracked state. (#9180)
New resolver: Discard a faulty distribution, instead of quitting outright. This implementation is taken from 20.2.2, with a fix that always makes the resolver iterate through candidates from indexes lazily, to avoid downloading candidates we do not need. (#9203)
New resolver: Discard a source distribution if it fails to generate metadata, instead of quitting outright. This implementation is taken from 20.2.2, with a fix that always makes the resolver iterate through candidates from indexes lazily, to avoid downloading candidates we do not need. (#9246)
Vendored Libraries¶
Upgrade resolvelib to 0.5.4.

20.3.2 (2020-12-15)¶
Features¶
Bug Fixes¶
New resolver: The “Requirement already satisfied” log is not printed only once for each package during resolution. (#9117)
Fix crash when logic for redacting authentication information from URLs in
--help
is given a list of strings, instead of a single string. (#9191)New resolver: Correctly implement PEP 592. Do not return yanked versions from an index, unless the version range can only be satisfied by yanked candidates. (#9203)
New resolver: Make constraints also apply to package variants with extras, so the resolver correctly avoids backtracking on them. (#9232)
New resolver: Discard a candidate if it fails to provide metadata from source, or if the provided metadata is inconsistent, instead of quitting outright. (#9246)
Vendored Libraries¶
Update vendoring to 20.8
Improved Documentation¶

20.3.1 (2020-12-03)¶
Deprecations and Removals¶
The --build-dir option has been restored as a no-op, to soften the transition for tools that still used it. (#9193)
20.3 (2020-11-30)¶
Deprecations and Removals¶
Remove --unstable-feature flag as it has been deprecated. (#9133)
Features¶
Bug Fixes¶
New Resolver: Rework backtracking and state management, to avoid getting stuck in an infinite loop. (#9011)
New resolver: Check version equality with
packaging.version
to avoid edge cases if a wheel used different version normalization logic in its filename and metadata. (#9083)New resolver: Show each requirement in the conflict error message only once to reduce cluttering. (#9101)
Fix a regression that made

Switch to the new dependency resolver by default. (#9019)
Remove the
--build-dir
option, as per the deprecation. (#9049)
Bug Fixes¶
Propagate
--extra-index-url
from requirements file properly to session auth, so that keyring auth will work as expected. (#8103)Allow specifying verbosity and quiet level via configuration files and environment variables. Previously these options were treated as boolean values when read from there while through CLI the level can be specified. (#8578)
Only converts Windows path to unicode on Python 2 to avoid regressions when a POSIX environment does not configure the file system encoding correctly. (#8658)
List downloaded distributions before exiting

Features¶
New resolver: Avoid accessing indexes when the installed candidate is preferred and considered good enough. (#8023)
Improve error message friendliness when an environment has packages with corrupted metadata. (#8676)
Cache package listings on index packages so they are guaranteed to stay stable during a pip command session. This also improves performance when a index page is accessed multiple times during the command session. (#8905)

20.2.3 (2020-09-08)¶
Deprecations and Removals¶
Deprecate support for Python 3.5 (#8181)
Features¶
Make the
setup.py install
deprecation warning less noisy. We warn only whensetup.py install
succeeded andsetup.py bdist_wheel
failed, as situations where both fails are most probably irrelevant to this deprecation. (#8752)
20.2.2 (2020-08-11)¶
Bug Fixes¶
Only attempt to use the keyring once and if it fails, don’t try again. This prevents spamming users with several keyring unlock prompts when they cannot unlock or don’t want to do so. (#8090)
Fix regression that distributions in system site-packages are not correctly found when a virtual environment is configured with
system-site-packages
on. (#8695)Disable caching for range requests, which causes corrupted wheels when pip tries to obtain metadata using the feature
fast-deps
. (#8701, #8716)Always use UTF-8 to read
pyvenv.cfg
to match the built-invenv
. (#8717)2020 Resolver: Correctly handle marker evaluation in constraints and exclude them if their markers do not match the current environment. (#8724)

.
) in the name and uninstall them when needed. (#8645)Trace a better error message on installation failure due to invalid
.data
files in wheels. (#8654)Fix SVN version detection for alternative SVN distributions. (#8665)
New resolver: Correctly include the base package when specified with extras in

mode. (#8677)Use UTF-8 to handle ZIP archive entries on Python 2 according to PEP 427, so non-ASCII paths can be resolved as expected. (#8684)
Improved Documentation¶
20.2 (2020-07-29)¶
Deprecations and Removals¶
Deprecate setup.py-based builds that do not generate an
.egg-info
directory. (#6998, #8617)Disallow passing install-location-related arguments in
--install-options
. (#7309)Add deprecation warning for invalid requirements format “base>=1.0[extra]” (#8288)
Deprecate legacy setup.py install when building a wheel failed for source distributions without pyproject.toml (#8368)
Deprecate -b/--build/--build-dir/--build-directory. Its current behaviour is confusing and breaks in case different versions of the same distribution need to be built during the resolution process. Using the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean covers known use cases. (#8372)
Remove undocumented and deprecated option
--always-unzip
(#8408)
Features¶
Log debugging information about pip, in
pip install --verbose
. (#3166)Refine error messages to avoid showing Python tracebacks when an HTTP error occurs. (#5380)
Install wheel files directly instead of extracting them to a temp directory. (#6030)
Add a beta version of pip’s next-generation dependency resolver.
Move pip’s new resolver into beta, remove the
--unstable-feature=resolver
flag, and enable the--use-feature=2020-resolver
flag. The new resolver is significantly stricter and more consistent when it receives incompatible instructions, and reduces support for certain kinds of Constraints Files, so some workarounds and workflows may break. More details about how to test and migrate, and how to report issues, at Changes to the pip dependency resolver in 20.3 (2020) . Maintainers are preparing to release pip 20.3, with the new resolver on by default, in October. (#6536)Introduce a new ResolutionImpossible error, raised when pip encounters un-satisfiable dependency conflicts (#8546, #8377)

Allow specifying
--prefer-binary
option in a requirements file (#7693)Generate PEP 376 REQUESTED metadata for user supplied requirements installed by pip. (#7811)
Warn if package url is a vcs or an archive url with invalid scheme (#8128)
Parallelize network operations in

pip
with--use-feature=fast-deps
. (#8588)Support
--use-feature
in requirements files (#8601)
Bug Fixes¶
Use canonical package names while looking up already installed packages. (#5021)
Fix normalizing path on Windows when installing package on another logical disk. (#7625)
The VCS commands run by pip as subprocesses don’t merge stdout and stderr anymore, improving the output parsing by subsequent commands. (#7968)
Correctly treat non-ASCII entry point declarations in wheels so they can be installed on Windows. (#8342)
Update author email in config and tests to reflect decommissioning of pypa-dev list. (#8454)
Headers provided by wheels in .data directories are now correctly installed into the user-provided locations, such as

Vendored Libraries¶
Upgrade packaging to 20.1
20.0.1 (2020-01-21)¶
Bug Fixes¶
Rename an internal module, to avoid ImportErrors due to improper uninstallation. (#7621)
20.0 (2020-01-21)¶
Process¶
Switch to a dedicated CLI tool for vendoring dependencies.
Deprecations and Removals¶
Remove wheel tag calculation from pip and use
packaging.tags
. This should provide more tags ordered better than in prior releases. (#6908)Deprecate setup.py-based builds that do not generate an
.egg-info
directory. (#6998)The pip>=20 wheel cache is not retro-compatible with previous versions. Until pip 21.0, pip will continue to take advantage of existing legacy cache entries. (#7296)
Deprecate undocumented
--skip-requirements-regex
option. (#7297)Deprecate passing install-location-related options via
--install-option
. (#7309)Use literal “abi3” for wheel tag on CPython 3.x, to align with PEP 384 which only defines it for this platform. (#7327)
Remove interpreter-specific major version tag e.g.
cp3-none-any
from consideration. This behavior was not documented strictly, and this tag in particular is not useful. Anyone with a use case can create an issue with pypa/packaging. (#7355)Wheel processing no longer permits wheels containing more than one top-level .dist-info directory. (#7487)
Support for the
git+git@
form of VCS requirement is being deprecated and will be removed in pip 21.0. Switch togit+https://
orgit+ssh://
.git+git://
also works but its use is discouraged as it is insecure. (#7543)
Features¶
Default to doing a user install (as if
--user
was passed) when the main site-packages directory is not writeable and user site-packages are enabled. (#1668)Warn if a path in PATH starts with tilde during
pip install
. (#6414)Cache wheels built from Git requirements that are considered immutable, because they point to a commit hash. (#6640)
Add option
--no-python-version-warning
to silence warnings related to deprecation of Python versions. (#6673)Cache wheels that
pip wheel
built locally, matching whatpip install
does. This particularly helps performance in workflows wherepip wheel
is used for building before installing. Users desiring the original behavior can usepip wheel --no-cache-dir
. (#6852)Display CA information in
pip debug
. (#7146)Show only the filename (instead of full URL), when downloading from PyPI. (#7225)
Suggest a more robust command to upgrade pip itself to avoid confusion when the current pip command is not available as
pip
. (#7376)Define all old pip console script entrypoints to prevent import issues in stale wrapper scripts. (#7498)
The build step of
pip wheel
now builds all wheels to a cache first, then copies them to the wheel directory all at once. Before, it built them to a temporary directory and moved them to the wheel directory one by one. (#7517)Expand
~
prefix to user directory in path options, configs, and environment variables. Values that may be either URL or path are not currently supported, to avoid ambiguity:--find-links
--constraint
,-c
--requirement
,-r
--editable
,-e
(#980)
Bug Fixes¶

after apep517
build error, since asetup.py
may not exist in that case. (#6642)Fix passwords being visible in the index-url in “Downloading <url>” message. (#6783)
Change method from shutil.remove to shutil.rmtree in noxfile.py. (#7191)
Skip running tests which require subversion, when svn isn’t installed (#7193)
Fix not sending client certificates when using
--trusted-host
. (#7207)Make sure
pip wheel
never outputs pure python wheels with a python implementation tag. Better fix/workaround for #3025 by using a per-implementation wheel cache instead of caching pure python wheels with an implementation tag in their name. (#7296)Include
subdirectory
URL fragments in cache keys. (#7333)Fix typo in warning message when any of
--build-option
,--global-option
and--install-option
is used in requirements.txt (#7340)Fix the logging of cached HTTP response shown as downloading. (#7393)
Effectively disable the wheel cache when it is not writable, as is the case with the http cache. (#7488)

Features¶
Configuration files may now also be stored under
sys.prefix
(#5060)Avoid creating an unnecessary local clone of a Bazaar branch when exporting. (#5443)
Include in pip’s User-Agent string whether it looks like pip is running under CI. (#5499)
A custom (JSON-encoded) string can now be added to pip’s User-Agent using the
PIP_USER_AGENT_USER_DATA
environment variable. (#5549)For consistency, passing
--no-cache-dir
no longer affects whether wheels will be built. In this case, a temporary directory is used. (#5749)Command arguments in
subprocess
log messages are now quoted usingshlex.quote()
. (#6290)Prefix warning and error messages in log output with WARNING and ERROR. (#6298)
Using
--build-options
in a PEP 517 build now fails with an error, rather than silently ignoring the option. (#6305)Error out with an informative message if one tries to install a
pyproject.toml
-style (PEP 517) source tree using--editable
mode. (#6314)When downloading a package, the ETA and average speed now only update once per second for better legibility. (#6319)
Bug Fixes¶
The stdout and stderr from VCS commands run by pip as subprocesses (e.g.
git
,hg
, etc.) no longer pollute pip’s stdout. (#1219)Fix handling of requests exceptions when dependencies are debundled. (#4195)

Bug Fixes¶
19.0.2 (2019-02-09)¶
Bug Fixes¶
Fix a crash where PEP 517-based builds using
--no-cache-dir
would fail in some circumstances with anAssertionError
due to not finalizing a build directory internally. (#6197)Provide a better error message if attempting an editable install of a directory with a
pyproject.toml
but nosetup.py
. (#6170)The implicit default backend used for projects that provide a
pyproject.toml
file without explicitly specifyingbuild-backend
now behaves more like direct execution ofsetup.py
, and hence should restore compatibility with projects that were unable to be installed withpip
19.0. This raised the minimum required version ofsetuptools
for such builds to 40.8.0. (#6163)Allow
RECORD
lines with more than three elements, and display a warning. (#6165)AdjacentTempDirectory
fails on unwritable directory instead of locking up the uninstall command. (#6169)Make failed uninstalls roll back more reliably and better at avoiding naming conflicts. (#6194)
Ensure the correct wheel file is copied when building PEP 517 distribution is built. (#6196)
The Python 2 end of life warning now only shows on CPython, which is the implementation that has announced end of life plans. (#6207)

Features¶
Allow PEP 508 URL requirements to be used as dependencies.
As a security measure, pip will raise an exception when installing packages from PyPI if those packages depend on packages not also hosted on PyPI. In the future, PyPI will block uploading packages with such external URL dependencies directly. (#4187)
Allows dist options (--abi, --python-version, --platform, --implementation) when installing with --target (#5355)

Deprecations and Removals¶
Removed the deprecated
--egg
parameter topip install
. (#1749)Removed support for uninstalling projects which have been installed using distutils. distutils installed projects do not include metadata indicating what files belong to that install and thus it is impossible to actually uninstall them rather than just remove the metadata saying they’ve been installed while leaving all of the actual files behind. (#2386)
Removed the deprecated
--download
option topip install
. (#2643)Removed the deprecated --(no-)use-wheel flags to
pip install
andpip wheel
. (#2699)Removed the deprecated
--allow-external
,--allow-all-external
, and--allow-unverified
options. (#3070)Switch the default for

. (#4449)Move all of pip’s APIs into the pip._internal package, properly reflecting the fact that pip does not currently have any public APIs. (#4696, #4700)
Features¶
Add --progress-bar <progress_bar> to
pip download
,pip install
andpip wheel
commands, to allow selecting a specific progress indicator or, to completely suppress, (for example in a CI environment) use--progress-bar off`
. (#2369, #2756)Add --no-color to pip. All colored output is disabled if this flag is detected. (#2449)
pip uninstall now ignores the absence of a requirement and prints a warning. (#3016, #4642)
Improved the memory and disk efficiency of the HTTP cache. (#3515)
Support for packages specifying build dependencies in pyproject.toml (see PEP 518). Packages which specify one or more build dependencies this way will be built into wheels in an isolated environment with those dependencies installed. (#3691)
pip now supports environment variable expansion in requirement files using only
${VARIABLE}
syntax on all platforms. (#3728)Allowed combinations of -q and -v to act sanely. Then we don’t need warnings mentioned in the issue. (#4008)
Add --exclude-editable to
pip freeze
andpip list
to exclude editable packages from installed package list. (#4015, #4016)Improve the error message for the common

to be used with a specific platform when--no-deps
is set. (#4289)Support build-numbers in wheel versions and support sorting with build-numbers. (#4299)
Change pip outdated to use PackageFinder in order to do the version lookup so that local mirrors in Environments that do not have Internet connections can be used as the Source of Truth for latest version. (#4336)
pip now retries on more HTTP status codes, for intermittent failures. Previously, it only retried on the standard 503. Now, it also retries on 500 (transient failures on AWS S3), 520 and 527 (transient failures on Cloudflare). (#4473)
pip now displays where it is looking for packages, if non-default locations are used. (#4483)
Display a message to run the right command for modifying pip on Windows (#4490)
Add Man Pages for pip (#4491)
Make uninstall command less verbose by default (#4493)
Switch the default upgrade strategy to be ‘only-if-needed’ (#4500)
Installing from a local directory or a VCS URL now builds a wheel to install, rather than running
setup.py install
. Wheels from these sources are not cached. (#4501)Don’t log a warning when installing a dependency from Git if the name looks like a commit hash. (#4507)
pip now displays a warning when it installs scripts from a wheel outside the PATH. These warnings can be suppressed using a new --no-warn-script-location option. (#4553)
Local Packages can now be referenced using forward slashes on Windows. (#4563)
pip show learnt a new Required-by field that lists currently installed packages that depend on the shown package (#4564)
The command-line autocompletion engine
pip show
now autocompletes installed distribution names. (#4749)Change documentation theme to be in line with Python Documentation (#4758)
Add auto completion of short options. (#4954)
Run ‘setup.py develop’ inside pep518 build environment. (#4999)
pip install now prints an error message when it installs an incompatible version of a dependency. (#5000)
Added a way to distinguish between pip installed packages and those from the system package manager in ‘pip list’. Specifically, ‘pip list -v’ also shows the installer of package if it has that meta data. (#949)
Show install locations when list command ran with “-v” option. (#979)
Bug Fixes¶
Allow pip to work if the
GIT_DIR
andGIT_WORK_TREE
environment variables are set. (#1130)Make

-q
specified once correctly sets logging level to WARNING, instead of CRITICAL. Use -qqq to have the previous behavior back. (#3994)Shell completion scripts now use correct executable names (e.g.,
pip3
instead ofpip
) (#3997)Changed vendored encodings from
utf8
toutf-8
. (#4076)Fixes destination directory of data_files when
pip install --target
is used. (#4092)Limit the disabling of requests’ pyopenssl to Windows only. Fixes “SNIMissingWarning / InsecurePlatformWarning not fixable with pip 9.0 / 9.0.1” (for non-Windows) (#4098)

Return the latest version number in search results. (#4219)
Improve error message on permission errors (#4233)
Fail gracefully when
/etc/image_version
(or another distro version file) appears to exists but is not readable. (#4249)Avoid importing setuptools in the parent pip process, to avoid a race condition when upgrading one of setuptools dependencies. (#4264)
Fix for an incorrect
freeze
warning message due to a package being included in multiple requirements files that were passed tofreeze
. Instead of warning incorrectly that the package is not installed, pip now warns that the package was declared multiple times and lists the name of each requirements file that contains the package in question. (#4293)Generalize help text for
compile
/no-compile
flags. (#4316)Handle the case when
/etc
is not readable by the current user by using a hardcoded list of possible names of release files. (#4320)Fixed a
NameError
when attempting to catchFileNotFoundError
on Python 2.7. (#4322)Ensure USER_SITE is correctly initialised. (#4437)
Reinstalling an editable package from Git no longer assumes that the
master
branch exists. (#4448)This fixes an issue where when someone who tries to use git with pip but pip can’t because git is not in the path environment variable. This clarifies the error given to suggest to the user what might be wrong. (#4461)
Improve handling of text output from build tools (avoid Unicode errors) (#4486)

editable option. (#1082)Fixed “TypeError: bad operand type for unary” in some cases when installing wheels using --find-links. (#1192, #1218)
Archive contents are now written based on system defaults and umask (i.e. permissions are not preserved), except that regular files with any execute permissions have the equivalent of “chmod +x” applied after being written. (#1133, #317, #1146)
PreviousBuildDirError now returns a non-zero exit code and prevents the previous build dir from being cleaned in all cases. (#1162)
Renamed --allow-insecure to --allow-unverified, however the old name will continue to work for a period of time. (#1257)
Fixed an error when installing local projects with symlinks in Python 3. (#1006, #1311)
The previously hidden
--log-file
option, is now shown as a general option. (#1316)
1.4.1 (2013-08-07)¶
New Signing Key Release 1.4.1 is using a different key than normal with fingerprint: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA

Fixes related to recognizing and cleaning global build dirs. (#1080)
1.4 (2013-07-23)¶
BACKWARD INCOMPATIBLE pip now only installs stable versions by default, and offers a new
--pre
option to also find pre-release and development versions. (#834)BACKWARD INCOMPATIBLE Dropped support for Python 2.5. The minimum supported Python version for pip 1.4 is Python 2.6.
Added support for installing and building wheel archives. Thanks Daniel Holth, Marcus Smith, Paul Moore, and Michele Lacchia (#845)
Applied security patch to pip’s ssl support related to certificate DNS wildcard matching (https://bugs.python.org/issue17980).
To satisfy pip’s setuptools requirement, pip now recommends setuptools>=0.8, not distribute. setuptools and distribute are now merged into one project called ‘setuptools’. (#1003)
pip will now warn when installing a file that is either hosted externally to the index or cannot be verified with a hash. In the future pip will default to not installing them and will require the flags --allow-external NAME, and --allow-insecure NAME respectively. (#985)
If an already-downloaded or cached file has a bad hash, re-download it rather than erroring out. (#963)
pip bundle
and support for installing from pybundle files is now considered deprecated and will be removed in pip v1.5.Fix a number of issues related to cleaning up and not reusing build directories. (#413, #709, #634, #602, #939, #865, #948)

Improvements to sphinx docs and cli help. (#773)
Fixed an issue dealing with macOS temp dir handling, which was causing global NumPy installs to fail. (#707, #768)
Split help output into general vs command-specific option groups. Thanks Georgi Valkov. (#744, #721)
Fixed dependency resolution when installing from archives with uppercase project names. (#724)
Fixed problem where re-installs always occurred when using file:// find-links. (#683, #702)
“pip install -v” now shows the full download url, not just the archive name. Thanks Marc Abramowitz (#687)
Fix to prevent unnecessary PyPI redirects. Thanks Alex Gronholm (#695)

Added support for --no-index in requirements files.
Added “pip show” command to get information about an installed package. Thanks Kelsey Hightower and Rafael Caricio. (#131)
Added --root option for “pip install” to specify root directory. Behaves like the same option in distutils but also plays nice with pip’s egg-info. Thanks Przemek Wrzos. (#253, #693)
1.2.1 (2012-09-06)¶
Fixed a regression introduced in 1.2 about raising an exception when not finding any files to uninstall in the current environment. Thanks for the fix, Marcus Smith.
1.2 (2012-09-01)¶
Dropped support for Python 2.4 The minimum supported Python version is now Python 2.5.
Fixed PyPI mirror support being broken on some DNS responses. Thanks philwhin. (#605)

gmpy2-2.0.tar.gz
from matching a request topip install gmpy
; sdist filename must begin with full project name followed by a dash. Thanks casevh for the report. (#510)Allow package URLS to have querystrings. Thanks W. Trevor King. (#504)
pip freeze now falls back to non-editable format rather than blowing up if it can’t determine the origin repository of an editable. Thanks Rory McCann. (#58)
Added a __main__.py file to enable python -m pip on Python versions that support it. Thanks Alexey Luchko.
Fixed upgrading from VCS url of project that does exist on index. Thanks Andrew Knapp for the report. (#487)
Fix upgrade from VCS url of project with no distribution on index. Thanks Andrew Knapp for the report. (#486)
Add a clearer error message on a malformed VCS url. Thanks Thomas Fenzl. (#427)
Added support for using any of the built in guaranteed algorithms in
hashlib
as a checksum hash.Raise an exception if current working directory can’t be found or accessed. (#321)
Removed special casing of the user directory and use the Python default instead. (#82)
Only warn about version conflicts if there is actually one. This re-enables using
==dev
in requirements files. (#436)Moved tests to be run on Travis CI: https://travis-ci.org/pypa/pip
Added a better help formatter.
1.1 (2012-02-16)¶
Don’t crash when a package’s setup.py emits UTF-8 and then fails. Thanks Marc Abramowitz. (#326)
Added
--target
option for installing directly to arbitrary directory. Thanks Stavros Korokithakis.Added support for authentication with Subversion repositories. Thanks Qiangning Hong.
--download
now downloads dependencies as well. Thanks Qiangning Hong. (#315)Errors from subprocesses will display the current working directory. Thanks Antti Kaihola.
Fixed compatibility with Subversion 1.7. Thanks Qiangning Hong. Note that setuptools remains incompatible with Subversion 1.7; to get the benefits of pip’s support you must use Distribute rather than setuptools. (#369)
Ignore py2app-generated macOS mpkg zip files in finder. Thanks Rene Dudfield. (#57)
Log to ~/Library/Logs/ by default on macOS framework installs. Thanks Dan Callahan for report and patch. (#182)

Handle symlinks properly. Thanks lebedov for the patch. (#288)
pip install -U no longer reinstalls the same versions of packages. Thanks iguananaut for the pull request. (#49)
Removed
-E
/--environment
option andPIP_RESPECT_VIRTUALENV
; both use a restart-in-venv mechanism that’s broken, and neither one is useful since every virtualenv now has pip inside it. Replacepip -E path/to/venv install Foo
withvirtualenv path/to/venv && path/to/venv/pip install Foo
.Fixed pip throwing an IndexError when it calls scraped_rel_links. (#366)
pip search should set and return a useful shell status code. (#22)
Added global
--exists-action
command line option to easier script file exists conflicts, e.g. from editable requirements from VCS that have a changed repo URL. (#351, #365)
1.0.2 (2011-07-16)¶
Fixed docs issues.

Download progress only shown on a real TTY. Thanks Alex Morega.
Fixed finding of VCS binaries to not be fooled by same-named directories. Thanks Alex Morega.
Fixed uninstall of packages from system Python for users of Debian/Ubuntu python-setuptools package (workaround until fixed in Debian and Ubuntu).
Added get-pip.py installer. Simply download and execute it, using the Python interpreter of your choice:
$ curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py $ python get-pip.py
This may have to be run as root.
Note
Make sure you have distribute installed before using the installer!
0.8.3¶
Moved main repository to GitHub: https://github.com/pypa/pip
Transferred primary maintenance from Ian to Jannis Leidel, Carl Meyer, Brian Rosner
Fixed no uninstall-on-upgrade with URL package. Thanks Oliver Tonnhofer. (#14)
Fixed egg name not properly resolving. Thanks Igor Sobreira. (#163)
Fixed Non-alphabetical installation of requirements. Thanks Igor Sobreira. (#178)
Fixed documentation mentions --index instead of --index-url. Thanks Kelsey Hightower (#199)

Fixed checking out the correct tag/branch/commit when updating an editable Git requirement. (#32, #150, #161)
Added ability to install version control requirements without making them editable, e.g.:
pip install git+https://github.com/pypa/pip/
(#49)
Correctly locate build and source directory on macOS. (#175)
Added
git+https://
scheme to Git VCS backend.
0.8.1¶

Added support for PyPI mirrors as defined in PEP 381, from Jannis Leidel.
Fixed git revisions being ignored. Thanks John-Scott Atlakson. (#138)
Fixed initial editable install of github package from a tag failing. Thanks John-Scott Atlakson. (#95)
Fixed installing if a directory in cwd has the same name as the package you’re installing. (#107)
--install-option=”--prefix=~/.local” ignored with -e. Thanks Ronny Pfannschmidt and Wil Tan. (#39)
0.8¶
Track which
build/
directories pip creates, never remove directories it doesn’t create. From Hugo Lopes Tavares.pip now accepts file:// index URLs. Thanks Dave Abrahams.
Various cleanup to make test-running more consistent and less fragile. Thanks Dave Abrahams.
Real Windows support (with passing tests). Thanks Dave Abrahams.
pip-2.7
etc. scripts are created (Python-version specific scripts)contrib/build-standalone
script creates a runnable.zip
form of pip, from Jannis LeidelEditable git repos are updated when reinstalled
Fix problem with
--editable
when multiple.egg-info/
directories are found.A number of VCS-related fixes for
pip freeze
, from Hugo Lopes Tavares.Significant test framework changes, from Hugo Lopes Tavares.
0.7.2¶
Set zip_safe=False to avoid problems some people are encountering where pip is installed as a zip file.
0.7.1¶
Fixed opening of logfile with no directory name. Thanks Alexandre Conrad.
Temporary files are consistently cleaned up, especially after installing bundles, also from Alex Conrad.
Tests now require at least ScriptTest 1.0.3.
0.7¶
Fixed uninstallation on Windows
Added
pip search
command.Tab-complete names of installed distributions for
pip uninstall
.Support tab-completion when there is a global-option before the subcommand.
Install header files in standard (scheme-default) location when installing outside a virtualenv. Install them to a slightly more consistent non-standard location inside a virtualenv (since the standard location is a non-writable symlink to the global location).
pip now logs to a central location by default (instead of creating
pip-log.txt
all over the place) and constantly overwrites the file in question. On Unix and macOS this is'$HOME/.pip/pip.log'
and on Windows it’s'%HOME%\\pip\\pip.log'
. You are still able to override this location with the$PIP_LOG_FILE
environment variable. For a complete (appended) logfile use the separate'--log'
command line option.Fixed an issue with Git that left an editable package as a checkout of a remote branch, even if the default behaviour would have been fine, too.
Fixed installing from a Git tag with older versions of Git.
Expand “~” in logfile and download cache paths.
Speed up installing from Mercurial repositories by cloning without updating the working copy multiple times.
Fixed installing directly from directories (e.g.
pip install path/to/dir/
).Fixed installing editable packages with
svn+ssh
URLs.Don’t print unwanted debug information when running the freeze command.
Create log file directory automatically. Thanks Alexandre Conrad.
Make test suite easier to run successfully. Thanks Dave Abrahams.
Fixed “pip install .” and “pip install ..”; better error for directory without setup.py. Thanks Alexandre Conrad.
Support Debian/Ubuntu “dist-packages” in zip command. Thanks duckx.
Fix relative --src folder. Thanks Simon Cross.
Handle missing VCS with an error message. Thanks Alexandre Conrad.
Added --no-download option to install; pairs with --no-install to separate download and installation into two steps. Thanks Simon Cross.
Fix uninstalling from requirements file containing -f, -i, or --extra-index-url.
Leftover build directories are now removed. Thanks Alexandre Conrad.
0.6.3¶
Fixed import error on Windows with regard to the backwards compatibility package
0.6.2¶
Fixed uninstall when /tmp is on a different filesystem.
Fixed uninstallation of distributions with namespace packages.
0.6.1¶
Added support for the
https
andhttp-static
schemes to the Mercurial andftp
scheme to the Bazaar backend.Fixed uninstallation of scripts installed with easy_install.
Fixed an issue in the package finder that could result in an infinite loop while looking for links.
Fixed issue with
pip bundle
and local files (which weren’t being copied into the bundle), from Whit Morriss.
0.6¶
Add
pip uninstall
and uninstall-before upgrade (from Carl Meyer).Extended configurability with config files and environment variables.
Allow packages to be upgraded, e.g.,
pip install Package==0.1
thenpip install Package==0.2
.Allow installing/upgrading to Package==dev (fix “Source version does not match target version” errors).
Added command and option completion for bash and zsh.
Extended integration with virtualenv by providing an option to automatically use an active virtualenv and an option to warn if no active virtualenv is found.
Fixed a bug with pip install --download and editable packages, where directories were being set with 0000 permissions, now defaults to 755.
Fixed uninstallation of easy_installed console_scripts.
Fixed uninstallation on macOS Framework layout installs
Fixed bug preventing uninstall of editables with source outside venv.
Creates download cache directory if not existing.
0.5.1¶
Fixed a couple little bugs, with git and with extensions.
0.5¶
Added ability to override the default log file name (
pip-log.txt
) with the environmental variable$PIP_LOG_FILE
.Made the freeze command print installed packages to stdout instead of writing them to a file. Use simple redirection (e.g.
pip freeze > stable-req.txt
) to get a file with requirements.Fixed problem with freezing editable packages from a Git repository.
Added support for base URLs using
<base href='...'>
when parsing HTML pages.Fixed installing of non-editable packages from version control systems.
Fixed issue with Bazaar’s bzr+ssh scheme.
Added --download-dir option to the install command to retrieve package archives. If given an editable package it will create an archive of it.
Added ability to pass local file and directory paths to
--find-links
, e.g.--find-links=file:///path/to/my/private/archive
Reduced the amount of console log messages when fetching a page to find a distribution was problematic. The full messages can be found in pip-log.txt.
Added
--no-deps
option to install ignore package dependenciesAdded
--no-index
option to ignore the package index (PyPI) temporarilyFixed installing editable packages from Git branches.
Fixes freezing of editable packages from Mercurial repositories.
Fixed handling read-only attributes of build files, e.g. of Subversion and Bazaar on Windows.
When downloading a file from a redirect, use the redirected location’s extension to guess the compression (happens specifically when redirecting to a bitbucket.org tip.gz file).
Editable freeze URLs now always use revision hash/id rather than tip or branch names which could move.
Fixed comparison of repo URLs so incidental differences such as presence/absence of final slashes or quoted/unquoted special characters don’t trigger “ignore/switch/wipe/backup” choice.
Fixed handling of attempt to checkout editable install to a non-empty, non-repo directory.
0.4¶
Make
-e
work better with local hg repositoriesConstruct PyPI URLs the exact way easy_install constructs URLs (you might notice this if you use a custom index that is slash-sensitive).
Improvements on Windows (from Ionel Maries Cristian).
Fixed problem with not being able to install private git repositories.
Make
pip zip
zip all its arguments, not just the first.Fix some filename issues on Windows.
Allow the
-i
and--extra-index-url
options in requirements files.Fix the way bundle components are unpacked and moved around, to make bundles work.
Adds
-s
option to allow the access to the global site-packages if a virtualenv is to be created.Fixed support for Subversion 1.6.
0.3.1¶
Improved virtualenv restart and various path/cleanup problems on win32.
Fixed a regression with installing from svn repositories (when not using
-e
).Fixes when installing editable packages that put their source in a subdirectory (like
src/
).Improve
pip -h
0.3¶
Added support for editable packages created from Git, Mercurial and Bazaar repositories and ability to freeze them. Refactored support for version control systems.
Do not use
sys.exit()
from inside the code, instead use a return. This will make it easier to invoke programmatically.Put the install record in
Package.egg-info/installed-files.txt
(previously they went insite-packages/install-record-Package.txt
).Fix a problem with
pip freeze
not including-e svn+
when an svn structure is peculiar.Allow
pip -E
to work with a virtualenv that uses a different version of Python than the parent environment.Fixed Win32 virtualenv (
-E
) option.Search the links passed in with
-f
for packages.Detect zip files, even when the file doesn’t have a
.zip
extension and it is served with the wrong Content-Type.Installing editable from existing source now works, like
pip install -e some/path/
will install the package insome/path/
. Most importantly, anything that package requires will also be installed by pip.Add a
--path
option topip un/zip
, so you can avoid zipping files that are outside of where you expect.Add
--simulate
option topip zip
.
0.2.1¶
Fixed small problem that prevented using
pip.py
without actually installing pip.Fixed
--upgrade
, which would download and appear to install upgraded packages, but actually just reinstall the existing package.Fixed Windows problem with putting the install record in the right place, and generating the
pip
script with Setuptools.Download links that include embedded spaces or other unsafe characters (those characters get %-encoded).
Fixed use of URLs in requirement files, and problems with some blank lines.
Turn some tar file errors into warnings.
0.2¶
Renamed to
pip
, and to install you now dopip install PACKAGE
Added command
pip zip PACKAGE
andpip unzip PACKAGE
. This is particularly intended for Google App Engine to manage libraries to stay under the 1000-file limit.Some fixes to bundles, especially editable packages and when creating a bundle using unnamed packages (like just an svn repository without
#egg=Package
).
0.1.4¶
Added an option
--install-option
to pass options to pass arguments tosetup.py install
.svn/
directories are no longer included in bundles, as these directories are specific to a version of svn -- if you build a bundle on a system with svn 1.5, you can’t use the checkout on a system with svn 1.4. Instead a filesvn-checkout.txt
is included that notes the original location and revision, and the command you can use to turn it back into an svn checkout. (Probably unpacking the bundle should, maybe optionally, recreate this information -- but that is not currently implemented, and it would require network access.)Avoid ambiguities over project name case, where for instance MyPackage and mypackage would be considered different packages. This in particular caused problems on Macs, where
MyPackage/
andmypackage/
are the same directory.Added support for an environmental variable
$PIP_DOWNLOAD_CACHE
which will cache package downloads, so future installations won’t require large downloads. Network access is still required, but just some downloads will be avoided when using this.
0.1.3¶
Always use
svn checkout
(notexport
) so thattag_svn_revision
settings give the revision of the package.Don’t update checkouts that came from
.pybundle
files.
0.1.2¶
Improve error text when there are errors fetching HTML pages when seeking packages.
Improve bundles: include empty directories, make them work with editable packages.
If you use
-E env
and the environmentenv/
doesn’t exist, a new virtual environment will be created.Fix
dependency_links
for finding packages.
0.1.1¶
Fixed a NameError exception when running pip outside of a virtualenv environment.
Added HTTP proxy support (from Prabhu Ramachandran)
Fixed use of
hashlib.md5
on python2.5+ (also from Prabhu Ramachandran)
0.1¶
Initial release
