贴一份本人的.vimrc参考，放在home目录下（~），并重命名为.vimrc，然后打开vim，执行如下指令即可安装：

:PlugInstall

说明：

leader键为;（小拇指按很方便~）
YouCompleteMe自然是必须的啦
airline
molokai主题
带注释
nerdtree
nerdcommenter
auto-pair
窗口跳转快捷键

具体如下：

set nocompatible              " be iMproved, required
set backspace=indent,eol,start
filetype off                  " required
