安装Vundle
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
Vundle也是vim的插件，所以放到~/.vim/bundle/下。
安装环境
# install CMake
sudo apt-get install build-essential cmake
# install Python
sudo apt-get install python-dev python3-dev
配置.vimrc
"set mouse=a
"set paste "取消自动注释
set selection=exclusive
set selectmode=mouse,key
set number
set tabstop=4
set softtabstop=4
set shiftwidth=4
set noexpandtab
set relativenumber number
set autoindent
set cindent
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
set nocompatible " be iMproved, required
filetype off " required
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
"
Plugin 'VundleVim/Vundle.vim'
Plugin 'https://gitee.com/mirrors/youcompleteme.git'
"这个就是YCM插件
call vundle#end() " required
filetype plugin indent on " required
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
let g:ycm_server_python_interpreter='/usr/bin/python3'
let g:ycm_global_ycm_extra_conf='~/.vim/.ycm_extra_conf.py'
let g:ycm_key_invoke_completion = '<c-z>'
let g:ycm_semantic_triggers = {
\ 'c,cpp,python,java,go,erlang,perl': ['re!\w{2}'],
\ 'cs,lua,javascript': ['re!\w{2}'],
\ }
let g:ycm_confirm_extra_conf = 1 "设置为0关闭加载提示
let g:ycm_autoclose_preview_window_after_completion = 1 " 关闭原型提示
let g:ycm_autoclose_preview_window_after_insertion = 1
"let g:ycm_key_list_select_completion = ['<C-o>', '<C-l>']
let g:ycm_show_diagnostics_ui = 0 "关闭语法诊断
然后运行:PluginInstall，等待安装完成。
然后编译YCM
cd ~/.vim/bundle/YouCompleteMe
python3 install.py --clang-completer
最后在项目目录下新建.ycm_extra_conf.py

PS
学到一点新东西
inoremap <expr> <Down> pumvisible() ? "\<C-n>" : "\<Down>"
i：插入状态下有效
nore：不递归
map：按键映射
pumvisible()：Returns non-zero when the popup menu is visible, zero otherwise. See ins-completion-menu.This can be used to avoid some things that would remove the popup menu.
大概意思就是vim弹出选择菜单时返回非0值，这时候按
