How to Upgrade All Python Packages at Once with pip?

Upgrading All Python Packages with pip

Is there an effortless method to upgrade all Python packages concurrently using pip?

pip currently lacks an intrinsic flag for this purpose. However, starting with version 22.3, two commands, --outdated and --format=freeze, can be combined to achieve the desired result.

Pip Version 22.3 and Above:

pip --disable-pip-version-check list --outdated --format=json | python -c "import json, sys; print('\n'.join([x['name'] for x in json.load(sys.stdin)]))" | xargs -n1 pip install -U

Pip Version Prior to 22.3:

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

Older Pip Versions:

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

Additional Considerations:

• The grep command filters out editable ("-e") package definitions.
• The -n1 flag for xargs allows individual package updates to fail without halting the entire process.

Variations:

Numerous variations of these commands exist. However, the above options provide a straightforward and functional approach for upgrading all Python packages with pip.
