Upgrading Multiple Python Packages Simultaneously Using Pip
While pip does not have a built-in command to upgrade all packages at once, there are workarounds to accomplish this.
One method is to employ Python to parse the JSON output from pip:
pip --disable-pip-version-check list --outdated --format=json | python -c "import json, sys; print('\n'.join([x['name'] for x in json.load(sys.stdin)]))" | xargs -n1 pip install -U
For pip versions prior to 22.3, an alternative command can be used:
pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U
For even older versions of pip:
pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip install -U
It's crucial to exempt editable package definitions ("-e") in the grep command. The -n1 switch for xargs suppresses errors encountered while upgrading specific packages.
While this answer provides a basic solution, various adaptations are possible based on specific requirements. Users are encouraged to explore and suggest modifications in the comments.
