⚠️ The issue is fixed thanks to @danielfleischer . Make sure to update the Emacs+ formula. Usually brew update does the trick.

This looks like a ruby syntax error, but I'm not a ruby programmer to be sure. This is not happening with other formulas, so reporting here.

Feels like an upstream issue.

@jberdine please try again :) @danielfleischer has fixed the issue on Emacs+ side 💯 Don't forget to update.

$ brew update
$ brew install emacs-plus@30 [options]

[jberdine]

Excellent, it works now, that was fast, thanks!

[bklebe]

I ran brew update and it's still broken. I untapped and retapped and I still can't get it to work. Is there some other cache I need to clear?

Make sure to actually update brew. What version are you on?

[bklebe]

@d12frosted I dug through the FAQ and ran this:

cd "$(brew --repository)"
git reset --hard FETCH_HEAD

Seems to have fixed it. Wasn't updating when I ran brew update for some reason.

[UnderGreen]

@bklebe That also worked for me. Thanks!

[bklebe]

@UnderGreen happy to help, this is often my first step when something in Brew won't update, but I can never remember the exact command they want you to do...should probably alias it.

[d12frosted]

Small update in this issue. Seems like I found a way to make it working with both version of Homebrew. See #569. Now all you have to do is to update to latest version of Emacs+:

$ brew update
$ brew install emacs-plus [options]

Sorry for troubles 🙏 the root cause was using private APIs. They changed and Emacs+ broke.
