"pip" is problematic on Linux as well (due to the pip/pip3 split at the system level). Hence this section in the stdlib docs: https://docs.python.org/3/installing/#work-with-multiple-versions-of-python-installed-in-parallel > If we can't get PATH sorted out, we need to do something about this, > IMO.

I personally believe we should aim to make the "Windows" section in the above link universal (i.e. working across *nix, Windows, and virtual environments). That's the only one that can feasibly be made universal - all the other alternatives are already known to be incompatible with particular scenarios. It's a fair bit of work to make it happen though, so it will likely remain a "wish list" item unless someone gets particularly inspired to do something about it :) Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
