Mcvim youcomplete hint

  question, vim


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

My vim has a prompt, but the prompt is all some characters in the current script. It does not prompt system library functions or other automatic input.
And pressing tab cannot complete it.

YCMForclangThe completion of depends onclang++ 3.70And above. In addition, completion is not necessarilytabYou have to see how vimrc is set up. mine isCtrl+j or kMake a choice

If everything is installed, open itvimAfter that, useVundleSee if the installation is successful, if it is successful, it may be a configuration problem.
The following is my ownYCMConfiguration in vimrc.bundle: see if it helps?
