Deoplete is the abbreviation of "dark powered neo-completion". It provides an asynchronous keyword completion system in the current buffer. To view the current options, please consult the documentation.


Note: deoplete requires Neovim(latest is recommended) with Python3 enabled. See requirements if you aren't sure whether you have this.

  1. Extract the files and put them in your Neovim directory (usually $XDG_CONFIG_HOME/nvim/).
  2. Execute the :UpdateRemotePlugins and restart Neovim.
  3. Write call deoplete#enable() or let g:deoplete#enable_at_startup = 1 in your init.vim

For vim-plug

Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }

For dein.vim

call dein#add('Shougo/deoplete.nvim')


deoplete requires Neovim with if_python3. If :echo has("python3") returns 1, then you're done; otherwise, see below.

You can enable Python3 interface with pip:

pip3 install neovim

Note: deoplete needs neovim-python ver.0.1.8+.

You need update neovim-python module.

pip3 install --upgrade neovim

If you want to read the Neovim-python/python3 interface install documentation, you should read :help provider-python and the Wiki.

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.
