For vim-plug

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

For dein.vim

call dein#add('Shougo/deoplete.nvim')
if !has('nvim')
  call dein#add('roxma/nvim-yarp')
  call dein#add('roxma/vim-hug-neovim-rpc')
endif
let g:deoplete#enable_at_startup = 1

Vim >= 8 built-in package manager (not recommended)

1. Clone the repo in a package (e.g. $XDG_CONFIG_HOME/nvim/pack/dist/start, where dist is the name of the package)

2. Write call deoplete#enable() or let g:deoplete#enable_at_startup = 1 in your init.vim

3. Inside NeoVim, call :UpdateRemotePlugins

Requirements

deoplete requires Neovim or Vim8 with if_python3.

If :echo has("python3") returns 1, then you have python 3 support; otherwise, see below.

You can enable Python3 interface with pip:

pip3 install --user pynvim

Please install nvim-yarp and vim-hug-neovim-rpc for Vim8.

• https://github.com/roxma/nvim-yarp
• https://github.com/roxma/vim-hug-neovim-rpc

Note: Python3 must be enabled before updating remote plugins

If Deoplete was installed prior to Python support being added to Neovim, :UpdateRemotePlugins should be executed manually in order to enable auto-completion.

Note: deoplete needs pynvim ver.0.3.0+.

You need update pynvim module.

pip3 install --user --upgrade pynvim
