BundleInstall，默认会出现错误
ycm_client_support.[so|pyd|dll] and ycm_core.[so|pyd|dll] not detected; you need to compile YCM before using it. Read the docs!
最简单解决方式：
cd ~/.vim/bundle/YouCompleteMe ./install.sh --clang-completer
另外，vimConfig/plugin/youCompleteMe-setting.vim
1 """"""""""""YCM"""""""""""""""""""" 2 let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py' 3 let g:ycm_collect_identifiers_from_tags_files = 1 4 let g:ycm_seed_identifiers_with_syntax = 1 5 let g:ycm_confirm_extra_conf = 0
添加自定义头文件路径
修改~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py
在 “flags = [ ” 后面加上两行：
'-isystem', '你的路径',
注意，路径不能用~/aaaa，要全路径，否则找不到。
