See #270 for the history (yes, I know it's a duplicate, but that didn't help)

Here's what I'm faced with now

Following the instructions in #260 didn't help at all, despite promising signs that it installed successfully.

So as you can see, Successfully installed luma.core-2.3.1 luma.led-matrix is in the output, but when I try to load a device from the module I get a 'ModuleNotFoundError'

Help! I'm slowly losing the will to carry on with this, everything I have tried is just broken

ianglennon commented

Oh, and I had to use 'sudo -H' to run pip3 because doing it as a user threw an error that directories could not be created

ianglennon commented

I have cleaned everything out, removed the luma.core (which did install) and luma.led_matrix (which failed because it wasn't installed, despite the line above which says it was) and purged the pip3 cache. This is what I did next, including the results...

Let's keep this in one ticket, having all feedback in a single ticket is only way to manage this. Duplicate of #269. If we fix the error in #269 and there are still issues, I will re-open this ticket.

This is working for me on Bullseye. But only in a virtual environment.
