Step1：配置.vimrc文件

vi ~/.vimrc

Step2：将本文最后附加的内容拷贝进去，:wq保存退出

Step3：安装插件管理器Vundle

mkdir -p ~/.vim/bundle/
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
vim
# 以下操作在vim界面中执行
:PluginList  # 遍历vimrc中的插件
:PluginInstall  #安装插件，将逐个自动安装，请确保git clone可用
:bdelete # 清除缓冲区缓存
:PluginClean  #删除插件
:PluginInstall!  #重新安装所有插件
:h vundle 查看更多说明
#我们也可以在不打开vim的情况下安装插件
vim +PluginInstall +qall

遇到过的问题

（1）YouCompleteMe unavailable: requires Vim compiled with Python (3.6.0+) support.

• 因为vim无法使用Python，mac可以通过brew重装vim，ubuntu可以通过Conda重装vim

vim --version | grep python # 如果得到的结果 python 2/3前面是个-号，说明vim没法用Python
brew install vim
echo "alias vim=/opt/homebrew/bin/vim" >> ~/.bash_profile

（2）The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). YCM core library not detected; you need to compile YCM before using it. Follow the instructions in the documentation.

• 因为YouCompleteMe这个插件需要到源仓库底下去编译，详见安装说明

cd ~/.vim/bundle/YouCompleteMe
/usr/bin/python3 install.py
