Description of issue

I noticed that I can't build ocaml. I keep getting this error message:

==> Upgrading dune

I have also been experiencing this issue recently.

After I set:

export HOMEBREW_NO_INSTALL_FROM_API=1

In the ~/.zshrc file, the issue was resolved.

This looks like a Homebrew bug. Can you open an issue at https://github.com/Homebrew/brew/issues/new?template=bug.yml? Thanks!

CC @Rylan12 as this may be related to your recent work.
