Flask-Migrate does not support Flask-Script any more.

See: miguelgrinberg/Flask-Migrate#407
should migrate to flask CLI: https://blog.miguelgrinberg.com/post/migrating-from-flask-script-to-the-new-flask-cli

Hi there, I've tried reading the documentation and from what I understand the issue is MigrateCommand doesn't exist in the first place with newer versions of Flask-Migrate migrate in which you can't use the manager.add_command method from Flask-Script. I've read the guide and do I even need to use the manager.add_command or it's successor Flask-Cli's equivalent?

from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate, MigrateCommand
from flask_script import Manager
#
app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:///database.db"

db = SQLAlchemy(app)
migrate = Migrate(app, db)

manager = Manager(app)
manager.add_command("db", MigrateCommand)

Simple downgrade to:

Flask-Migrate==2.5.2
Flask-Script==2.0.6

to make it work.

You could use pip install --force-reinstall flask_migrate==2.5.2 and afterwards same trick with flask-script. I would recommend doing this in a virtual env, since you only need it for this one instance.
