Python：“ImportError：在没有已知父包的情况下尝试相对导入”

Question

I'm working on the capstone project for Udacity's Full Stack Web Developer. I consider myself a beginner developer so please be kind:D

I'm working on the backend for my project but I'm getting stuck with this error:

 (env) C:\Repos\FSND_Capstone_Project\backend>flask db init Usage: flask db init [OPTIONS] Error: While importing "api", an ImportError was raised: Traceback (most recent call last): File "c:\repos\fsnd_capstone_project\backend\env\lib\site-packages\flask\cli.py", line 236, in locate_app __import__(module_name) File "C:\Repos\FSND_Capstone_Project\backend\api.py", line 9, in <module> from.database.models import setup_db, Manager, Project, Category ImportError: attempted relative import with no known parent package

I also have the following folder structure that I'm trying to create:

[Folder structure]

I don't see what the error might be. Any tip of advice will be very well received.

I also attached my Github's repo link:

Thanks in advance!

You have to from database.models import setup_db because .database.models only works if backend is a package itself (has a __init__.py file)
