vim-hug-neovim-rpc: Vim cannot find neovim module

Since a few days, I get the following error message when launching Vim on my (uptodate) Archlinux x86_64 :

[vim-hug-neovim-rpc] Vim(pythonx):ImportError: No module named neovim 
Error detected while processing function deoplete#enable[9]..deoplete#initialize[1]..deoplete#init#_initialize[10]..<SNR>120_ini
t_internal_variables[28]..neovim_rpc#serveraddr:
line   18:
E605: Exception not caught: [vim-hug-neovim-rpc] requires one of `:pythonx import [pynvim|neovim]` command to work

I think the problem occured after an update, either to my System (there has been a lot of python packages updated recently) or to my Vim Plugins after a PlugUpdate.

To solve the this problem, I tried different solutions found on the Web, but no luck. Finally, I uninstalled several packages pip, neovim, greenlet, … and reinstalled neovim.

$ sudo pip3 install neovim

but without success, error remains the same !

Vim says :

:echo has('python')   --> 1
:echo has('python3')   --> 0
:echo has('pythonx')   --> 1

Please, can you help ?

My Vim version is :

@hutou Please read :help has-python.

							*has-python*
You can test what Python version is available with: >
	if has('python')
	  echo 'there is Python 2.x'
	endif
  	if has('python3')
	  echo 'there is Python 3.x'
	endif

Note however, that when Python 2 and 3 are both available and loaded
dynamically, these has() calls will try to load them.  If only one can be
loaded at a time, just checking if Python 2 or 3 are available will prevent
the other one from being available.

To avoid loading the dynamic library, only check if Vim was compiled with
python support: >
	if has('python_compiled')
	  echo 'compiled with Python 2.x support'
	  if has('python_dynamic')
	    echo 'Python 2.x dynamically loaded'
	  endif
	endif
  	if has('python3_compiled')
	  echo 'compiled with Python 3.x support'
	  if has('python3_dynamic')
	    echo 'Python 3.x dynamically loaded'
	  endif
	endif

This also tells you whether Python is dynamically loaded, which will fail if
the runtime library cannot be found.

I think Python2 is loaded before Python3 in your environment. So, Python2 is used and pynvim module is not installed in Python2.

You need to set python3 manually.

set pyxversion=3
