Pip 22.3, list: List format 'freeze' can not be used with the --outdated option?

$ pip3 list --outdated --format=freeze
ERROR: List format 'freeze' can not be used with the --outdated option.

Doc says otherwise – pip list - pip documentation v22.3

What would be the equivalent of pip3 list --outdated --format=freeze in pip 22.3 and newer?

A PR for a doc update would be welcomed.

From the changelog

Remove the ability to use pip list --outdated in combination with --format=freeze. (#9789)

this change was made in issue 9789. In that issue, I provide an alternative:

Actually, if you want the output @matrixise expects, the following gives it:

> py -m pip list --outdated --format=json | jq -r '.[] | .name+\"=\"+.latest_version'

(excuse Powershell quoting rules, for Unix probably just omit the backslashes).

(But note that as per the discussion in the issue, this does not provide a list of requirements that will necessarily “upgrade everything” the way you would expect. See the issue for details).


So on mac, this works:

python3 -m pip list --outdated --format=json | jq -r '.[] | "\(.name)==\(.latest_version)"' | xargs -n1 pip3 install -U
