CentOS 7下Vim安装YouCompleteMe插件

最权威的原始步骤可以参考github中关于此插件的README.md，如果时间允许的话，尽量多看几遍可以避免很多不必要的麻烦。一.版本检测
使用vim --version指令，检 vim版本是否大于7.3.584，一般新系统都满足。打开vim，输入下述指令查看是否支持python。如果显示为1，则表示支持python；如果显示为0，则表示不支持python，需要重新下载编译vim，使其支持python。:echo has（"python"）
二.下载Vundle和YouCompleteMe插件
输入以下指令，下载Vundlegit clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim
下载成功后，在用户根目录下面，修改.vimrc文件，追加下面语句以便后续安装YouCompleteMe插件set nocompatible
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin（）
Plugin "gmarik/Vundle.vim"
Plugin "Valloric/YouCompleteMe"
call vundle#end（）
filetype plugin indent on
然后在vim中先按Esc建，并且输入以下指令安装插件：:PluginInstall
三.编译YouCompleteMe
在编译之前下载编译工具，准备编译YouCompleteMesudo yum install automake gcc gcc-c++ kernel-devel cmake
sudo yum install python-devel python3-devel
编译YouCompleteMe使其支持C/C++ 自动补全cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer四.配置vim
修改.vimrc文件let g:ycm_global_ycm_extra_conf = "/home/li/.vim/bundle/YouCompleteMe/.ycm_extra_conf.py
let g:ycm_seed_identifiers_with_syntax=1 " 语法关键字补全
let g:ycm_confirm_extra_conf=0 " 打开vim时不再询问是否加载ycm_extra_conf.py配置
inoremap <expr> <CR> pumvisible（）？ "<C-y>" : "<CR>" "回车即选中当前项
set completeopt=longest,menu "让Vim的补全菜单行为与一般IDE一致（参考VimTip1228）
