Python : Fix error with pip and pylupdate6.exe .

I try to upgrade the PyQt6 package and I got this error:

pip3 install --upgrade --force-reinstall PyQt6
...
ERROR: Could not install packages due to an OSError: [WinError 2] The system cannot find the file specified:
...pylupdate6.exe
...pylupdate6.exe.deleteme'

I think this solution will work for any python package

Open a command shell run as administrator and run it again:

pip3 install --upgrade --force-reinstall PyQt6
Collecting PyQt6
...
Successfully installed PyQt6-6.4.1 PyQt6-Qt6-6.4.2 PyQt6-sip-13.4.1

If you want to re-download the packages instead of using the files from your pip cache, then use:

pip install --force-reinstall --no-cache-dir
