Neovim do not work on mac

Question

I installed neovim v0.2.2 via homebrew:

$ brew install neovim
$ alias n="nvim -u $XDG_CONFIG_HOME/nvim/init.vim"

Then, neovim causes many errors, so I cannot use it.

1. First, when I open a file, say n foo.rb, the filetype is not detected: :set ft? gives filetype=.
2. Second, I tried :CheckHealth, but it is said Not an editor command: CheckHealth. I also tried :checkhealth, giving Invalid 'runtimepath'. So I checked :set rtp?, but it seems to be right.
3. Third, when I entered insert mode, deoplete raised an error Unknown function js_encode.
4. Finally, I could not copy texts to clipboard "+y.

I think there must be more errors I have not found.

I checked :set rtp?, but it is OK. And all key mappings [nvics][nore]map work correctly, so init.vim is certainly loaded.

These errors occur only after updating neovim from v0.2.0 to v0.2.2. They do not occur when I used v0.2.0.

Environments:

• mac OS 10.12.6
• neovim v0.2.2

Answer 1

Something went wrong with Oni. I rm all files concerning oni, :call dein#update(), and :UpdateRemotePlugins, then Neovim recovered.
