How to debug dependency not installed?

[tekumara]

My app fails on run with ModuleNotFoundError: No module named 'numpy'.
I suspect numpy is failing to install for python 3.13.
How can I debug or get verbose info for the dependency installation phase?

Can you provide some more information on how you are creating the app (env. variables, project structure)? How do you declare the requirements?

I’m just using

PYAPP_PROJECT_NAME=fakesnow
PYAPP_PROJECT_VERSION=0.9.27

Looking at fakesnow and the pyproject.toml, it seems like numpy is not listed as a dependency. If I actually just create a fresh virtual environment, install fakesnow from pip and then open python and import it, I get the same error. This would be the same way that PyApp runs the import.
Hope this helps!

Thank you for looking into this! I realise now I had numpy installed already in my virtualenv, so wasn't seeing this when testing the install from pip 🤦

Awesome, glad it works. No worries, easy to overlook such things, especially when your in the depth of it.
