1：安装mvim，直接装个7.4版本以上，不要再纠结7.3X支持python了
brew install mvim brew install cmake
2：链接下
ln -s /usr/local/bin/mvim /usr/local/bin/vim
3：安装Vundle
git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim
4：配置.vimrc，这里的配置是为了安装plugin用，最后可以自行配置
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()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')
" let Vundle manage Vundle, required
Plugin 'gmarik/Vundle.vim'
Plugin 'altercation/vim-colors-solarized'
Plugin 'Lokaltog/powerline', {'rtp': 'powerline/bindings/vim/'}
Plugin 'kien/ctrlp.vim'
Plugin 'scrooloose/syntastic'
Plugin 'Valloric/YouCompleteMe'
" All of your Plugins must be added before the following line
call vundle#end() " required
filetype plugin indent on " required
5：装起
vim :BundleInstall
6：手动
在process到YouCompleteMe的时候，报错，这是正常的，手动来下
cd .vim/bundle/YouCompleteMe/ git submodule update --init --recursive ./install.sh --clang-completer --system-libclang
中途会报一些错误Xcode相关的，不要去理，太矫情

安装完之后，应该就Ok了
7：关于.ycm_extra_conf.py的传闻，直接看说明和一个范例吧，世界那么大，搜搜啥都会有
https://github.com/Valloric/YouCompleteMe https://github.com/Valloric/ycmd/blob/master/cpp/ycm/.ycm_extra_conf.py
8：自己的.vimrc里只需要添加下面几行
set rtp+=~/.vim/bundle/Vundle.vim call vundle#begin() Plugin 'Valloric/YouCompleteMe' call vundle#end() filetype plugin indent on
最后提供一个网盘关于YouCompleteMe文件夹的内容下载，主要是git那步速度靠人品的，十分缓慢

附图两张，第二张图里malloc.h头文件写错了都指出来了
