1.安装YouCompleteMe
在.vimrc中插入
Plugin 'Valloric/YouCompleteMe'利用git下载安装包
git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe然后进入YouCompeteMe所在的文件夹：~/.vim/bundle/YouCompleteMe，运行：
python3 install.py --clang-completer --system-libclang其中编译安装的过程中，不断提示编译所缺少的依赖，会有错误提示，按照提示安装缺少的依赖就好，其中比较重要的是clang，所以先需要运行
sudo apt-get install clang运行install.py时会显示
最后在.vimrc文件中，添加配置信息：
set ts=4
set expandtab
set shiftwidth=4
set softtabstop=4
set number
"vundle"
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
