vim ruby mismatch on Mac High Sierra

This worked for me. YMMVbrew uninstall --purge macvimbrew 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.

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 vimvim: 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

➜  ~ vimdyld: 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
