Question

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.

Answer 1

There isn’t a built-in flag yet. Starting with pip version 22.3, the --outdated and --format=freeze have become mutually exclusive. Use Python, to parse the JSON output:

pip --disable-pip-version-check list --outdated --format=json | python -c "import json, sys; print('\n'.join([x['name'] for x in json.load(sys.stdin)]))" | xargs -n1 pip install -U

If you are using pip<22.3 you can use:

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

For older versions of pip:

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).

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!
