Answer 1

➜  ~ vim
dyld: Library not loaded: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib
  Referenced from: /usr/local/bin/vim
  Reason: image not found

I tried brew uninstall install update... All failed. And install_name_tool works for me.

install_name_tool -change /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/libruby.2.3.0.dylib /usr/local/bin/vim
