dart run serious_python:main package dont install modules into the zip file?

[kiwimarc]

I'm trying to run this command:
dart run serious_python:main package ..\python-engine\ --asset assets/python/app.zip -p Windows --requirements '-r ..\..\assets\python\requirements.txt' --verbose

It seems like its running great:

But when I then run the app, I dont have access to any of the install modules? I can also confirm this in the zip file, that it only makes a copy of my Python files.

What am I doing wrong?

[kiwimarc]

The same issue is seen in the run_example.

I also can't replicate the results from the GitHub action, where I just tried to run the Windows part of the action.

[Can1425]

Yes, I just encountered exactly the same situation. My solution is to execute the command: project_root\build\build_python_3.12.9\python\python.exe -m pip install --target C:\tmp\python_bundle\__pypackages__ -r xxxxxxxxxx

Then you can add C:\tmp\python_bundle\__pypackages__ to the compressed package.

@Can1425 Yeah, I also figured that one out, but then the documentation should still be updated. And a second issue is that numpy doesn't like how it's installed, because numpy thinks it's in its root directory

It probably won't be like this, maybe you can try sys.path.append?🧐
