为什么我安装不上去 neovim for Python ? ruby 也配置不好，我已经升级到最新了呢。

我已经安装了 python2 & 3. pip install neovim & pip3 install neovim, nvim +checkhealth，还是报这个错误呢。

谷歌了好半天，各种方法也试过了，没有解决。上来问一下大家，有没有碰到过。

哎，这 python 的版本管理，是真的闹心......

谢谢！

p.s.

let g:python_host_prog = '/usr/bin/python' let g:python3_host_prog = '/usr/bin/python3' let g:ruby_host_prog = '/Users/yazoox/.rvm/rubies/ruby-2.4.1/bin/ruby' 

编辑一下，刚才把 python3 的路径改成和了 /usr/local/bin/python
