1 背景
2 将VIM打造成IDE
2.1 CTags插件
2.2 CScope插件
2.3 nerdtree插件
2.4 YouCompleteMe插件
a. vim一定要是最新版，mac系统自带的vim可能有问题，可以通过brew来安装一个最新的macvim。
b. vim必须要支持python脚本，打开vim，在命令模式下输入 echo has('python') || has('python3')，如果输出1，则可以继续往下了。
c. 系统要安装cmake，如果没有cmake，用brew安装。
d. 系统要安装python-dev，mac默认已经带了这个。
http://releases.llvm.org/download.html。选择最新版的CLang For macOS。
