Pip Upgradeall

I have been using Function PipUpgradeall { pip list -o --format=freeze | % {pip install -U $_.split("=")[0]} } to do pip-upgradeall for a long time. However pip 22.3 disabled this function saying ERROR: List format 'freeze' can not be used with the --outdated option. See pypa/pip#11482

So I have to parse pip list -o manually. It turns out usable.

Usage:

pip install git+https://github.com/imba-tjd/pipupgradeall
pipupgradeall
