Actually this is exactly what is recommended here: https://stackoverflow.com/questions/59558343/cant-install-pyqt5-on-raspberry-pi However a different post suggests there is a bug in the pyqt5 pyproject.toml. https://stackoverflow.com/questions/59462014/cant-install-pyqt5-using-pip-on-raspberry-pi I just wonder why upgrading pip "fixes" this bug. thanks again,
