foreman start no module named myapp

Question

I'm following the heroku quick start guide here: https://devcenter.heroku.com/articles/getting-started-with-python

and I'm stuck on the foreman start part. This is what my directory looks. I'm just running a basic web app. No frameworks or anything.

soapbar/
    Procfile.txt
    soapbar/
        soapbar.py
    venv/
        Include/
        Lib/
        Scripts/ 

This is the stack trace:

Any ideas?

Answer 1

Add a file named __init__.py to the soapbar/ folder. Leave it empty.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable.
