#{formula.name} was installed from the #{Formatter.identifier(installed_tap_name)} tap
but you are trying to install it from the #{Formatter.identifier(current_tap_name)} tap.
Formulae with the same name from different taps cannot be installed at the same time.
To install this version, you must first uninstall the existing formula:
brew uninstall #{formula.name}
Then you can install the desired version:
brew install #{formula.full_name}
