Metadata Generation Failed

[Lizzit]

I'm trying to install the dependencies for the GUI and i found out that there is a problem installing the pyqt5-tools library. Each and every time i try to install it, it send me the following error:

 error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.

SPECS:

• Windows - 11
• Python - 3.12.2
• PyQt5 - 5.15.10

Using Python 3.11 should fix this issue. Adam used 3.8 during development.

[Lizzit]

ok, but with the two version of python installed how can i call the pip of the 3.11 instead of the pip of the 3.12 using windows? Using each time this is really time consuming:

C:/Users/user/AppData/Local/Programs/Python/Python311/python.exe -m pip install ...

[adamtheone]

I'd suggest using a virtual environment (venv), or have only that python version installed, or search solutions for pyqt5 in the relevant forums/threads.
