答:进入YouCompleteMe的安装目录安装一些必要的依赖
比如:笔者将YouCompleteMe安装到了~/.vim/bundle目录下,那么执行以下操作:
cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer --system-libclang
(如果出现安装失败，请尝试添加选项--no-regex,也就是./install.py --clang-completer --system-libclang --no-regex)

A:
4.1 将配置文件复制到对应的目录中
mkdir ~/.vim/bundle/YouCompleteMe/cpp/ycm -p
cp ~/.vim/bundle/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/.vim/bundle/YouCompleteMe/cpp/ycm
4.2 配置.vimrc
echo "let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'" >> ~/.vimrc
