Tasklib not found when installing with Vim-plug

[fullstopslash]

I was catching this error on Mac Big Sur. No matter where I seemed to install tasklib.

Error detected while processing function provider#python3#Call:

It turns out, as I'm using Vim-Plug to manage my plugins I guess it does some kind of sandboxing for each plugin.

The solution to get it working was to copy the libraries for pytz, six, tzlocal, and tasklib, to the plugin's directory for python. In my case ~/.vim/plugged/taskwiki/pythonx/ I hope this helps anyone who runs into this in the future!

Vim-plug does not do any sandboxing on its own, but I think the issue is that the system python and the python available from vim on Mac OSX use different locations for site-packages.

In my case I would get the same error on my system with vim, but not with neovim.

Mac OS X	Homebrew: brew install task 
Homebrew: brew install taskd 
Homebrew: brew install tasksh 

I got those install steps from https://taskwarrior.org/download/.

Doing pip[3] install tasklib makes taskwiki work in both vim and neovim. I totally missed doing that as somehow neovim was able source tasklib...
