Following the Python steps for making a Homebrew formula, I'm running into a problem where a cryptography release doesn't compile inside my formula.

How to repro

• brew create --python --set-name "repro" https://github.com/splitgraph/sgr/archive/refs/tags/v0.3.10.tar.gz
• paste the contents of repro.rb over the file that opens
• run brew install --verbose --debug --build-from-source repro

repro.rb

    # ENV.deparallelize  # if your formula fails when building in parallel

  end

  test do
    # `test do` will create, run in and delete a temporary directory.
    #
    # This test will fail and we won't accept that! For Homebrew/homebrew-core
    # this will need to be a test that verifies the functionality of the
    # software. Run the test with `brew test repro`. Options passed
    # to `brew install` such as `--HEAD` also need to be provided to `brew test`.
    #
    # The installed folder is not in the path, so use the entire path to any
    # executables being tested: `system "#{bin}/program", "do", "something"`.
    system "false"
  end
