Though this seems more like a workaround than a fix.

We’re working on a real/better fix.

I’ve made a mitigation here that may have fixed things. Please don’t set export HOMEBREW_NO_INSTALL_FROM_API=1 but try again and, if you still see errors after I posted this message, let me know if this is a problem.

Please see https://github.com/Homebrew/homebrew-cask/issues/141436#issuecomment-1432900362

There is a workaround, found at https://github.com/Homebrew/brew/issues/14542

export HOMEBREW_NO_INSTALL_FROM_API=1

That seems to be a direct result of 4.0.0 release: https://brew.sh/2023/02/16/homebrew-4.0.0/ Weirdly, is says:

[…] the HOMEBREW_INSTALL_FROM_API variable has been removed and is a no-op

If you wish to opt-out of this behaviour change, you can export HOMEBREW_NO_INSTALL_FROM_API=1

I guess the first sentence is wrong because that workaround worked for me 🤷

Seems to be fixed for me after running brew update

@carlocab

GitHub has pushed a mitigation on their side. Please let us know if you’re still having this problem. You’ll need to do unset HOMEBREW_NO_INSTALL_FROM_API to try to trigger it.

This is the work around

export HOMEBREW_NO_INSTALL_FROM_API=1
