ModuleNotFoundError: No module named 'flask._compat' in Flask 3.0.0

[SWS-5007]

Hi,
When I run python project by using py manage.py command, I am getting error below.

Administrator@DESKTOP-BM42CU5 MINGW64 /e/tellmewhentogo_backend (main)
$ py manage.py
Traceback (most recent call last):
File "E:\tellmewhentogo_backend\manage.py", line 6, in
from flask_script import Manager, Shell
File "C:\Users\HOME\AppData\Local\Programs\Python\Python310\lib\site-packages\flask_script_init_.py", line 15, in
from flask._compat import text_type
ModuleNotFoundError: No module named 'flask._compat'

Here is my environment info.

Python 3.10.8
Flask 3.0.0  
Werkzeug 3.0.1

And here is my manage.py codebase.

import os
from app import create_app, db, bcrypt, marketManager
from app.models.role import Role
from app.models.user import User
from app.models.market import Market
from flask_script import Manager, Shell
from flask_migrate import Migrate

import warnings
warnings.filterwarnings("ignore")

app = create_app(os.getenv('FLASK_CONFIG') or 'default')
manager = Manager(app)
migrate = Migrate(app, db)


def make_shell_context():
    return dict(app=app, db=db, User=User)

manager.add_command("shell", Shell(make_context=make_shell_context))

@manager.command
def runserver():
    marketManager.initialize()
    app.run()

@manager.command
def dev():
    marketManager.initialize()
    app.run(port=5001)
    
@manager.command
def test():
    import unittest
    tests = unittest.TestLoader().discover('tests')
    unittest.TextTestRunner(verbosity=2).run(tests)

@manager.command
def createDb():
    db.create_all()

   
@manager.command
def dbInit():
    market = Market('BTCUSDT')
    db.session.add(market)
    db.session.commit()

if __name__ == '__main__':
    manager.run()

And here is the entire source code.

How to fix the current error?
Please help me.

Flask-Script is dead. It has been last updated in 2017 and the repo is archived since 2020. Use the built-in flask cli (based on click) instead.

Can you teach me the correct codebase by using built-in flask cli?
Actually, I have no experience in this part.

I recommend reading the Flask documentation and quickstart guide. And if that project you linked to is something you did right now, stop using whatever obsolete book/tutorial/video is telling you to use flask-script.

Okay, got it.
Thanks so much for your helps.
