I'm learning Flask by watching a YouTube tutorial

I'm getting an error:

Error:
ImportError: attempted relative import with no known parent package

from . import db
from flask_login import UserMixin
from sqlalchemy.sql import func

It says error is in line 1, this is my first time importing using a period at front.

But my folder structure and code is what's in Github link

from . import db

Anyone? Apparently this is a common error and easy to fix, but I can't figure it out.

When I run main.py, this is what I'm getting for errors.

Error:
Traceback (most recent call last):
  File "C:\Users\user\Desktop\database\main.py", line 3, in <module>
    app = create_app()
  File "C:\Users\user\Desktop\database\website\__init__.py", line 24, in create_app
    create_database(app)
  File "C:\Users\user\Desktop\database\website\__init__.py", line 38, in create_database
    db.create_all(app=app)
TypeError: SQLAlchemy.create_all() got an unexpected keyword argument 'app'

Change create_database to this.

def create_database(app):
    if not path.exists('website/' + DB_NAME):
        with app.app_context():
            db.create_all()
        print('Created Database!')

If problem running remove debug=True in main.py.

Thank you that worked.

If you're getting an error when trying to import a module, make sure you have the right version installed!
