I'm trying to use neovim with deoplete and UtilSnips. Both requires Python support from nvim.
I followed the instructions in :help nvim_python to set the support but the output of :echo has('python') or :echo has('python3') are both 0.
On nvim-startup I get the message UltiSnips requires py >= 2.7 or py3 and for deoplete It requires Neovim with Python 3 support ("+python3").
My python (2.7.10) and python3 (3.4.3) are both installed with homebrew. The neovim module is installed over pip and pip3 with install neovim but nvim can't find it, even when I set the let g:python_host_prog path in nvimrc.
I don't know what I am able to do anymore, has anyone an idea whats wrong with it?
Answer
Please follow the instruction on https://neovim.io/doc/user/provider.html#provider-python to setup the python interpreter for neovim.
First, install pynvim (previously, it was named neovim, but that has been changed) plugin
pip3 install pynvim
Print g:loaded_python3_provider
echo g:loaded_python3_provider
" for python 2.x use the following
" echo g:loaded_python_provider
If it returns 1, the python is not setup for neovim. In your ~/.config/nvim/init.vim file, set the python interpreter
let g:python3_host_prog='/path/to/python3'
" for python2, use the following instead
"let g:python_host_prog = '/path/to/python2.7'
