brew audit --online --new-formula fails for uses_from_macos [...], since: :monterey

[pavelzw]

I am currently trying to build a formula for micromamba. There, I have the issue that micromamba uses needs curl >= 7.66.0 while macOS 11 ships an older version. To fix this, I added uses_from_macos "curl", since: monterey (same thing with libarchive). Now, brew audit --online --new-formula micromamba returns the following error:

==> brew audit micromamba --online --new-formula
==> FAILED
Full audit micromamba --online --new-formula output
  micromamba:
    * Dependency 'curl' is provided by macOS; please replace 'depends_on' with 'uses_from_macos'.
    * Dependency 'libarchive' is provided by macOS; please replace 'depends_on' with 'uses_from_macos'.
  Error: 2 problems in 1 formula detected

This error only occurs in the macOS 11 CI runs.

How can I make brew stop complaining?

You could try adding it to exception list, like here #4623
