Same here. I installed six and am now getting the error message about name 'cache' is not defined.

[adambair]

Same

[fullstopslash]

This same error has started popping up for me as well.

The same on Mac

[dixonge]

Same error on Mac 12.6, BUT - this is with vim, not nvim

you need to check the version vim is running python on

if you're using homebrew, homebrew does this genius thing where it upgrades your packages without really clearly communicating this to you if you're not paying attention. Homebrew "helpfully" does an upgrade during normal package install, which appears to also affect the version of python vim is compiled against

so if you've installed the tasklib/six/packaging package with a python version, it may not be the python version currently running... so double check the python version you're running with vim above, and if its different than the version you already isntalled the dependencies with reinstall them again:
python3.X -m pip install [DEPENDENCIES], where X is the python version you found above in vim....

I think we can probably close this issue, but may want to leave it open so others can find this thread
