Upgrading all packages with pip

 

Is it possible to upgrade all Python packages at one time with pip ?

Note that there is a feature request for this on the official issue tracker.

There isn't a built-in flag yet, but you can use 

pip freeze --local | grep -v '^-e' | cut -d = -f 1  | xargs -n1 pip install -U

Note: there are infinite potential variations for this. I'm trying to keep this answer short and simple, but please do suggest variations in the comments!

Relevant edits:

  • Added a grep to skip "-e" package definitions, as suggested by @jawache (Yes, you could replace grep + cut with sed or awk or perl or...).

  • Newer versions of pip allow you to list outdated packages: 

    pip list --outdated --format=freeze

  • Added -n1 to xargs , prevents stopping everything if updating one package fails (thanks @andsens)

    • You can use the following Python code. Unlike pip freeze , this will not print warnings and FIXME errors. 

    import pip
from subprocess import call

packages = [dist.project_name for dist in pip.get_installed_distributions()]
call("pip install --upgrade " + ' '.join(packages), shell=True)

    To upgrade all local packages; you could use pip-review : 

    $ pip install pip-review
$ pip-review --local --interactive

    pip-review is a fork of pip-tools . See pip-tools issue mentioned by @knedlsepp. pip-review package works but pip-tools package no longer works.

    pip-review works on Windows since version 0.5.
