[deoplete] deoplete requires vim-hug-neovim-rpc plugin in Vim on clean installation #1029

Closed evandrocoan closed 5 years ago

Problems summary

I have put on my .vimrc:

" https://github.com/junegunn/vim-plug/wiki/tips
if empty(glob('~/.vim/autoload/plug.vim'))
  silent !curl -fLo ~/.vim/autoload/plug.vim --create-dirs
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif

call plug#begin('~/.vim/plugged')

if has('nvim')
  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
else
  Plug 'Shougo/deoplete.nvim'
  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'
endif
let g:deoplete#enable_at_startup = 1

" Initialize plugin system
call plug#end()

I have run the commands:

  1. rm -r .vim
  2. vim 
    1 Updated. Elapsed time: 2.731396 sec.

Please upload :messages result.

Your environment seems broken.

Shougo commented 5 years ago

And you should read vim-hug-neovim-rpc requirements.

https://github.com/roxma/vim-hug-neovim-rpc#requirements

evandrocoan commented 5 years ago

The environment cannot be broken because I deleted the ~/.vim directory before vim-plug plugin run the command I showed on the first post.

The output of vim :messages has only the line

[deoplete] deoplete requires vim-hug-neovim-rpc plugin in Vim.

I will look into the vim-hug-neovim-rpc installation instructions.

Shougo commented 5 years ago

OK. I get the problem.

+cryptv          +linebreak       -python          +vreplace
+cscope          +lispindent      -python3         +wildignore

You need to enable Python 3 interface for Vim.

evandrocoan commented 5 years ago

Big thanks! I will follow these steps

  1. https://vi.stackexchange.com/questions/11526/how-to-enable-python-feature-in-vim
  2. https://vi.stackexchange.com/questions/12827/how-to-install-vim-with-python-support-for-debian-strech

And see if I can make it +python

evandrocoan commented 5 years ago

Just to be sure, I deleted the ~/.vim directory again, and I installed vim-nox which has -python but +python3. Now deoplete throws this error after installing everything, exiting vim and opening it back:

evandrocoan commented 5 years ago

The vim-hug-neovim-rpc installation is working because they say I should run the command :echo neovim_rpc#serveraddr() to check if the vim-hug-neovim-rpc installation is working. Then, after running it, it correctly printed /tmp/v4Hoig3/0 as they say it should: https://github.com/roxma/vim-hug-neovim-rpc#requirements

Shougo commented 5 years ago

Hm...

Please test the command manually.

$ vim
:echo neovim_rpc#serveraddr()
$ python3 -u /root/.vim/plugged/nvim-yarp/pythonx/yarp.py {neovim_rpc#serveraddr() result} 'deoplete'  # in another terminal
Shougo commented 5 years ago

I recommend for you to use neovim instead.

evandrocoan commented 5 years ago
  1. :echo neovim_rpc#serveraddr() /tmp/vTlxiCt/0
  2. python3 -u /root/.vim/plugged/nvim-yarp/pythonx/yarp.py /tmp/vTlxiCt/0 'deoplete'

I think you missed the number 2. In that case, the output is:

Shougo commented 5 years ago

OK. I get it.

Note: deoplete requires Neovim (0.3.0+) or Vim8 (latest is recommended) with
Python3.6.1+ and |+timers| enabled.

Please use Python 3.6.1+.
