Deoplete não está funcionando para Neovim

Question

Portanto, instalei o neovim e o deoplete plugin. Eu chamei :UpdateRemotePlugins depois. Agora, quando escrevo C/C++ code, simplesmente não conclui. Ele realmente funciona para coisas como patht = ~/Desktop/ , que realmente recebe o menu pop-up. Ou Python code também recebe conclusões. Mas, por enquanto, estou escrevendo principalmente em C++ , então gostaria de fazê-lo funcionar. Eu tenho o Python 3.6 e 2.7.x. Eu fiz pip3 install neovim . Eu fiz call deoplete#enable() e eu até tentei let g:deoplete#enable_at_startup = 1 (deoplete está funcionando, mas não para C/C++ ). Eu tentei deoplete_clang , não conclui também. Onde está o problema? Esta é a saída de :CheckHealth :

E esta é minha init.vim :

call plug#begin('~/.config/nvim/plugged')
Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
" call PlugInstall to install new plugins
call plug#end()

call deoplete#enable()

filetype plugin indent on
set number
set nowrap
set tabstop=4
set shiftwidth=4
set autoindent
syntax on
set noswapfile
set nobackup

Existe uma maneira de fazer isso funcionar? Tenho certeza de que também tenho as últimas neovim e deoplete . Eu estou usando o Fedora 26.
