@tracyone 嗯，确实，多谢

@chemzqm 港真，我暂时找找不到比 Neovim+Deoplete 更好的组合了

brew install 出来的 vim 和 macvim 编译选项有问题，自己到 YouCompleteMe 官网看，有这段说明，
推荐直接下载 MacVim ，然后手工安装，然后命令行版本:

Question: I'm trying to use a Homebrew Vim with YCM and I'm getting segfaults

Answer: Something (I don't know what) is wrong with the way that Homebrew configures and builds Vim. I recommend using MacVim. Even if you don't like the MacVim GUI, you can use the Vim binary that is inside the MacVim.app package (it's MacVim.app/Contents/MacOS/Vim) and get the Vim console experience.
