Please read the documentation.

Q: deoplete does not work...

A: Please check followings.

  1. Please update neovim to latest version.

  2. Please update neovim python3 module to latest version.
>
    $ sudo pip3 install neovim --upgrade
<
  3. Please execute |:UpdateRemotePlugins| command manually.

  4. Please check if Python3 interface works.  You can check it by ":echo
  has('python3')" command.

I think your neovim python3 library and neovim binary are too old.

[mhartington]

Updated both and still get the errors

[Shougo]

Really?
Please upload the log file and your minimal .nvimrc.

Why don't you read the CONTRIBUTION.md?

[Shougo]

Current master neovim-python is 0.0.38.
Please upload your neovim-python's version.

Hmmm, more digging, seems there's a conflict with another plugin. I can't replicate it with a minimal vimrc, so I'll close this for now and report back when I find out whats the conflict. Sorry for the noise!

[Shougo]

OK.

Just as an update, it seems that installing deoplete on a place that is not ~/.vim/plugged causes this error. This happened when I changed the plugins directory to ~/.config/nvim/plugged.
