Problem summary

Just did a fresh install of deoplete, python-jedi and then deoplete-jedi and I encounter this errer every time I try to edit a python file and also when doing :PlugInstall

Environment Information

• OS: Arch Linux latest (kernel: 5.5.5-arch1-1)
• Neovim version: NVIM v0.4.3

Provide a minimal init.vim with less than 50 lines (required)

set runtimepath+=~/path/to/deoplete.nvim/
set runtimepath+=~/path/to/deoplete-jedi/
call plug#begin('~/.vim/plugged')
Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
call plug#end()
Plug 'deoplete-plugins/deoplete-jedi'

let g:deoplete#enable_at_startup = 1

Generate logfiles if appropriate

[deoplete] Traceback (most recent call last):

ModuleNotFoundError: No module named 'deoplete.base'
Could not load source: /home/luca/.vim/plugged/deoplete-jedi/rplugin/python3/deoplete/sources/deoplete_jedi.py.

This shows up, after entering insert mode in a python file

Steps to reproduce the issue after starting Neovim (required)

1. install deoplete, python-jedi and deoplete-jedi
2. open neovim on a python file
3. enter insert mode

Screen shot (if possible)

I don't reproduce the problem. I think your deoplete version is not the latest

And this is wrong.

set runtimepath+=~/path/to/deoplete.nvim/
set runtimepath+=~/path/to/deoplete-jedi/
call plug#begin('~/.vim/plugged')
Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
call plug#end()
Plug 'deoplete-plugins/deoplete-jedi'

call plug#end() must be after Plug 'deoplete-plugins/deoplete-jedi'.

yes, the version was the problem. python-msgpack in the official arch linux repositories is version 0.6.2 running sudo pip3 install -U msgpack solved the issue

[Shougo]

OK.
