@Fetz Hi,
It seems your python-client not latest version. Could you update latest and retry?
If you still occur error, Please repost error log.

Edit: FYI, My environment is almost the same as you

[zchee]

@Fetz Oh, just in case, you install neovim using brew, so I thought also installed Python in brew.
Recommend of update python-client command are
pip3 --no-cache-dir install -U git+https://github.com/neovim/python-client.git

That's use pip3(not python2) and ignore pip cache, also fetch the git HEAD.

[sdemura]

Ran into this issue too, @Fetz.

@zchee -- your tip worked. Thanks!

[zchee]

@sdemura Yeah 🎉

[Fetz]

thank you @zchee is working for me too, after updating python-client!

[raddevon]

I'm still getting this error after updating the python-client. Anything else I should try?

[Shougo]

I don't know the problem.
You should create new issue.

[raddevon]

@Shougo I was able to fix my problem by uninstalling and reinstalling deoplete.

[Shougo]

OK
