An open and ongoing feature request for PIP is to add an
upgrade-all command to
PIP. Due to the lack of this feature a workaround is required. Enter Stackoverflow.
I have been using a variation of this particular command line trick for awhile, but when starting writing this up I googled other solutions and this is one of the nicest and most straightforward I have seen.
pip freeze --local | grep -v '^\-e' | cut -d = -f 1 | xargs pip install -U
So next time you want to upgrade all the packages in your virtualenv, this is a great
place to start. I have this set up as an alias to
pipup in my .zshrc for convenience.
