Want to use plugins like Deoplete, Hyperstyle and other Python plugins on OSX, you need a working installation of both Python2 and Python3 managed by Homebrew (ie, system default Python isn't enough).
brew install python brew install python3 pip2 install neovim --upgrade pip3 install neovim --upgrade
To complete this, add this to your
let g:python2_host_prog = '/usr/local/bin/python' let g:python3_host_prog = '/usr/local/bin/python3'
And of course, you have to have Neovim installed for this. The repo homebrew-neovim has all the info on how to do this.
brew install neovim/neovim/neovim
You can use the
:HealthCheck command to see issues with your Python providers.
