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. 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.
