Dependency issues seen using pyqtdeploy 3.x, where 2.x seemed to work fine

Wed Jan 26 14:59:25 GMT 2022

Good day, Phil and everyone else on the pyqt listserv J,

I have been working with Gerard to try and get around the issue he posted, in email, below, and have a few questions:

1. Is there any suggestion for how to workaround the ModuleNotFoundError: No module named 'asyncio' issue Gerard is seeing?

2. Is there any technical explanation of how a package such as “argparse” is loaded differently from a stdlib one such as “asyncio”, which would be causing the ModuleNotFoundError?

Thank you for your assistance so far; We are hoping to be able to figure out a workaround for these pyqtdeploy issues in 3.x, that we previously did not see in 2.x.

Warmest regards,

Justin Vieira

So I'm still failing to solve issues on some stdlib packages such as asyncio.

1. I've modified pyqt-demo.py so that it import asyncio

2. Added "Python:asyncio" to "parts" list in pyqt-demo.pdt

3. Rebuilt (linux-64 target). Then observe

Traceback (most recent call last):
  File "pyqt-demo.py", line 11, in <module>
    import asyncio
  File "bootstrap-3.7.0.py", line 983, in _find_and_load
  File "bootstrap-3.7.0.py", line 965, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'asyncio'

So, what is the way to include packages such as asyncio? This doesn't seem to happen for packages such as argparse.
