mac vim youcomplete prompt - mac vim

Question

1.brew install vim
2.Install vundle plug-in manager
3.Install youcomplete plug-in

My vim has a prompt, but the prompts are only some characters in the current script. It does not prompt system library functions or other automatic input.
And you can’t complete it even by pressing the tab key.

Answer 1

YCM 对于clang的补全需要依赖clang++ 3.70及以上的版本。另外补全不一定是tab, 你得看看.vimrc怎么设置的，我的是ctrl + j或者kMake your choice

If everything is installed, then open vim之后，使用Vundle看看是不是安装成功，如果成功的话，那可能是配置问题了，
下面是我本机的YCMthe configuration in vimrc.bundle: See if it helps?
