How to upgrade all Python packages with pip

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

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U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!

In older version of pip, you can use this instead:

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

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

The -n1 flag for 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.For pip < 10.0.1

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

For pip >= 10.0.1

import pkg_resourcesfrom subprocess import callpackages = [dist.project_name for dist in pkg_resources.working_set]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.
