YouCompleteMe unavailable: requires Vim compiled with Python 2.x support or crash

I’ve installed and have YCM working with vim, I wanted to move over to neovim for better window support.

vim and vundle are already working but I get a crash when I try to setup neovim to work with YCM

I installed neovim with brew as directed in the readme for mac. brew tap neovim/neovim brew install --HEAD neovim

this part goes smoothly and I can launch neovim, the problem, there’s no color or syntax highlighting like in my vim. So I follow the instructions to create symbolic links for that brew recommends.

ln -s ~/.vimrc ~/.nvimrc
ln -s ~/.vim ~/.nvim

my machine has pip pip2 and pip3 installed Brother:~ blubee$ which pip /usr/local/bin/pip Brother:~ blubee$ which pip2 /usr/local/bin/pip2 Brother:~ blubee$ which pip3 /usr/local/bin/pip3

but neovim isn’t installed under any of them, currently

python: Brother:~ blubee$ python Python 2.7.10 (default, Sep 23 2015, 04:34:14) [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.72)] on darwin Type “help”, “copyright”, “credits” or “license” for more information.

quit()

Brother:~ blubee$ which python /usr/local/bin/python

when I do pip2 install --user neovim, that runs just fine but I get a crash as soon as I try to run vim or neovim.

This is my .nvimrc which is a symlink of my .vimrc

I should say a similar issue. Mine doesn’t crash, just complains YouCompleteMe unavailable: requires Vim compiled with Python 2.x support when python --version shows 2.7.10 and sudo pip install neovim was successful.
