I get these error messages:

Error: pyqt@4 from cartr/qt4 is given, but old name pyqt was installed from homebrew/core.
Please try to use pyqt to refer to the formula.
To force migration use `brew migrate --force pyqt`.

Error: pyqt 5.13.2 is already installed
To upgrade to 5.14.0, run `brew upgrade pyqt`.

Trying to upgrade gives me the same error as my original message.
