pip#

Usage#

python -m pip <command> [options]
py -m pip <command> [options]

Description#

Logging#

Console logging#

pip offers -v, --verbose and -q, --quiet to control the console log level. By default, some messages (error and warnings) are colored in the terminal. If you want to suppress the colored output use --no-color.

File logging#

pip offers the --log option for specifying a file where a maximum verbosity log will be kept. This option is empty by default. This log appends to previous logging.

Like all pip options, --log can also be set as an environment variable, or placed into the pip config file. See the Configuration section.

--exists-action option#

This option specifies default behavior when path already exists. Possible cases: downloading files or checking out repositories for installation, creating archives. If --exists-action is not defined, pip will prompt when decision is needed.

(s)witch

Only relevant to VCS checkout. Attempt to switch the checkout to the appropriate URL and/or revision.

(i)gnore

Abort current operation (e.g. don’t copy file, don’t create archive, don’t modify a checkout).

(w)ipe

Delete the file or VCS checkout before trying to create, download, or checkout a new one.

(b)ackup

Rename the file or checkout to {name}{'.bak' * n}, where n is some number of .bak extensions, such that the file didn’t exist at some point. So the most recent backup will be the one with the largest number after .bak.

(a)bort

Abort pip and return non-zero exit status.

Build System Interface#

This is now covered in Build System Interface.
