Deoplete.nvim: UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte

Problems summary

I just updated this plugin with PlugUpdate (using vim-plug). When I go into insert mode, this plugin basically explodes with errors.

I've narrowed this down to this commit: https://github.com/Shougo/deoplete.nvim/commit/0b84100ae775a6a1d1436c81a71bbeaeba241ab6

If I use this plugin with the commit before the one mentioned above, it works fine.

Expected

Not have it blow up in my face when I go into insert mode, haha.

Same issue here, since the last upgrade

I don't think this is the problem of deoplete. Can you show your neovim version?

[indiesquidge]

NVIM 0.1.4

[HerringtonDarkholme]

Also, can you give a pip3 install -U neovim? I also encounter this by updating. A reinstall of python3's neovim module might help.

Thanks @herringtonDarkholme `pip3 install -U nevoid' seems to work.

Seems that updating python's neovim module solves this issue. Thanks for everyone's help.

[Shougo]

deoplete requires neovim-python ver.0.18+.
