ModuleNotFoundError: No module named 'PyQt6' using Thonny for Windows

[teejayuu]

Hello,

I am following the PyQt6 tutorial using the Thonny IDE in Windows 11,and when I run the script I get the following error:

Traceback (most recent call last):
  File "C:\Users\tonyj\Scripts\Python\app.py", line 1, in <module>
    from PyQt6.QtWidgets import QApplication, QWidget
ModuleNotFoundError: No module named 'PyQt6'

If I call the script from Python it works perfectly. I've also tried it in PvCharm and VSCode: both display the same error. All systems (Windows, Python, Pip etc) are all at the latest version.

Thanks

Hi and welcome to devnet,

I didn't know it's existence so there are a couple of things. You seem to have an existing Python setup on your system, correct ?
Thonny comes with its own Python environment if installed through its package.
So:

• How did you install Thonny ?
• If through its official package, did you install PyQt6 from within the IDE ?
• If wanting to use your existing Python environment, did you follow the separate install wiki page ?
