vim ruby mismatch on Mac High Sierra

Question

I recently upgraded my Mac to High Sierra

After the upgrade, Macvim (mvim) stopped working because (I assume) HighSierra upgraded ruby to 2.3, and mvim

Answer 1

This worked for me:

$ brew update

$ brew upgrade macvim

actual command output:

[bin]$ brew upgrade macvim

Answer 2

This worked for me. YMMV brew uninstall --purge macvim brew install macvim

[amended] Regarding the upgrade alone option, that may work if you don't have the current version already. The --purge forces a removal and complete reinstall. Also, the build from source option, while it may work, you now own your own mac-vim static snapshot and need to maintain it manually as the app evolves. I'd avoid building from source unless you have very specific needs.

➜  ~ 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

Answer 4

What helped in my case was:

brew link --overwrite vim

In your case, it might be useful to use the same command for MacVim

brew link --overwrite macvim

Answer 5

First find where is the right libruby path, mine is: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/libruby.2.3.0.dylib

It is common that the version has changed.

Find out where the absolute path of vim is:

$ which vim
vim: aliased to your-path-of-vim

change dyld:

sudo 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 your-path-of-vim

Answer 6

Tried to use brew upgrade macvim an error was raised and the failed. What worked for me is to open the MacVim in a normal window (not a iTerm or terminal) the graphic version noticed that a newer version is available and asked if I want to update. Clicked yes, please and done. macvim in terminal or iTerm works just fine (as well as the "window" version).
