[External] Re: Running PyQt6 with Debug Modules

Fri Aug 26 15:04:58 BST 2022

Hi Florian,

Unfortunately that wasn't it, I was running python_d.exe and python.exe from the same location and running with the -v flag as you suggested indicated that they were both looking in the same place for the modules please see the images and output below, however, it should be easy for you to test, I'm on windows with a default vanilla Python 3.10 installation, I installed PyQt6 using pip into that installation, then simply run the code I posted originally in the python.exe and then in the python_d.exe for the same installation.

python.exe ( release console ) output as text:

As you can see it's not a difference in python installations...

Many thanks

As far as I know, you don't need to have a debug Qt/PyQt to use it with a debug Python. It looks like you simply have two separate installs of Python, and only have PyQt installed in one of them.

If you run your python_d.exe with the -v flag, it will show you where it's trying to find modules you are importing. If you compare those paths to the python.exe ones, that should give you an idea of what's missing.

How to build PyQt6 from source is documented pretty well:
