This addresses an issue in #1495.
I set up a new machine and ran
brew bundle cleanup --verbose
which then exited with the following error:This is because I hadn't installed anything and therefore
Formulary.factory
couldn't find the formula.With this change, I'm making an assumption that if we can't find the formula, we don't need to keep its associated tap and therefore it's fine to ignore the exception and consequently not include the tap in
kept_taps
.I would like to add a test case butI found spec/stub/exceptions.rb.TapFormulaUnavailableError
isn't available and wasn't sure it was desired to define it for testing. Let me know if I should.
