App build succeeds with Pyinstaller version 4.3 but not 4.4 due to AttributeError: Module 'PyQt5' has no attribute '__version__'

I'm using Python 3.9.5 and wanted to upgrade my Pyinstaller to the most recent version since I was encountering problems getting my app notarized. Everything worked fine with version 4.3, but building with 4.4 failed and resulted in a lengthy message ending with

AttributeError: Module 'PyQt5' has no attribute '__version__'

How can I resolve this?

Solution

  • I fixed it on my system by following:

    pip install PyQt5 --user --use-feature=2020-resolver

    pip install pyqtwebengine jedi parso pyqt5

    (If asked / not present on your system)
