I'm trying to install Watchman using Homebrew on macOS 10.15, but I'm encountering an error. Here's the command I ran and the output:
brew install watchman
And here's the error message I received:
==> Downloading https://formulae.brew.sh/api/formula.jws.json

Do not report this issue to Homebrew/brew or Homebrew/homebrew-core!
Error: You are using macOS 10.15.
We (and Apple) do not provide support for this old version.

Try to figure out the problem yourself and submit a fix as a pull request.
We will review it but may or may not accept it.
I also tried installing the Folly dependency separately using 'brew install folly', but I still encountered the same error.
Platform Specification:
- macOS 10.15.7
- Xcode 12.4
- Homebrew 4.2.8
It seems like the error is related to compatibility with macOS 10.15. Is there a workaround for this issue?
