new installation causes errors. FAB won't start.

[richlysakowski]

Environment

Flask-Appbuilder version: 4.5.0
Python 3.12.5
sqlalchemy 1.4.49

Describe the expected results

I created a new environment on Windows 10 Professional.

conda create -n flask_appbuilder_tools python conda pip flask-appbuilder sqlalchemy

I have a lot of experience with conda and it is my preferred way to build production systems.
This is my first time trying FAB.

Tell us what should happen.

FAB should open up without errors. 

Describe the actual results

Tell us what happens instead.

Debugged import:

• 'config' not found.

Original exception:

ModuleNotFoundError: No module named 'config'

Steps to reproduce

I tried starting it several times and got the same error. Anything I type I get the "config not found" fatal error.

Are you sure you have the config module inside this fab_first in some way?
It's very hard to find the error if you don't show:

• the layout of the dir
• where is located the entrypoint to your app object
• does config module exist?
  I suggest to have a look here for how application discovery happens:
• https://flask-appbuilder.readthedocs.io/en/latest/cli.html
• https://flask.palletsprojects.com/en/2.3.x/cli/
