you did run instal.py right? It's not in your steps, but it is clearly necessary (if you read the install docs).

I'm not sure that would account for the Vim version error, but that could be a separate issue (like we're just reporting the wrong error)

What is the output of the command :echo v:version in Vim?

So, it's an issue with your version of Vim, not YCM (the command should return 800 with Vim 8.0). My guess is that you are starting system Vim instead of the Homebrew one. Did you install MacVim with the following command:

brew install macvim --with-override-system-vim

? The --with-override-system-vim option will create symlinks such that typing vim in a terminal will start MacVim instead of system Vim.

Sorry about this really late reply.

You were right about the diagnosis.
Many many thanks for you time and effort - for a noob like me, you have
been a god send - stuff is working for me now.

@micbou Good Job

[yantaq]

In my case my vi editor (:echo v:version --> 703) was invoked instead of vim (:echo v:version --> 800).
following got rid of the error.

• [ ] alias vi="vim"
• [ ] export EDITOR=/path/to/vim
