neovim python-client when using in a virtualenv

[diefans]

This is not a bug, but a documentation suggestion.

I tried out neovim with YouCompleteMe and all my python plugins (python-mode, virtualenv) enabled. Everything works fine and all vim plugins are loaded.

But when someone works within a virtualenv the thing is breaking. My solution to this is to install the python client into a virtualenv itself and setting PYTHONPATH=~/.virtualenvs/neovim/lib/python2.7/site-packages

I use pyenv and ran into a similar problem, could you send a PR with some notes for pyenv/virtualenv users?

Are you appending that PYTHONPATH to the active PYTHONPATH when you've loaded a virtualenv? I am going to need to solve this too, and I'm not sure how best to go about it.

[diefans]

its just in my .bashrc, so neovim will be available in the system env and also in every activated virtualenv.

when there is a new nvim/neovim release, just workon neovim && pip install -U neovim && deactivate

I always activate the project specific virtual env before running vim, I don't switch between virtual envs within an edit session (by vim plugins) - so I cannot tell you if there are any issues with that...

@tarruda How did you solve this while using pyenv virtualenv? Adding to my PYTHONPATH the location of site-packages that include the neovim package doesn't seem to be solving the problem for me. When I have pyenv enabled for anything but the system package, neovim doesn't find Python.

[xanderdunn]

It looks like pointing neovim to my Homebrew Python installation did it: let g:python_host_prog = '/usr/local/bin/python'

@xanderdunn Thank you for that—that did the trick for me after much difficulty.

@xanderdunn Worked for me too, cheers.

I wrote up a wiki about setting up Neovim with Python: https://github.com/tweekmonster/nvim-python-doctor/wiki

There's a page dedicated to pyenv which could be helpful to new Neovim users.

I think this was resolved by :CheckHealth, @tweekmonster LMK if not.
