[SOLVED] flask db init using flask migrate

flask db init using flask migrate

I was try to migrate my database using flask_migrate when i was hitting the flask db init that time getting below error.

 Error: While importing 'app', an ImportError was raised:

Traceback (most recent call last):
  File "C:\Users\Admin\Desktop\Flask REST APIs\.venv\lib\site-packages\flask\cli.py", line 245, in locate_app    __import__(module_name)
  File "C:\Users\Admin\Desktop\Flask REST APIs\app.py", line 6, in <module>
    from db import db
  File "C:\Users\Admin\Desktop\Flask REST APIs\db.py", line 1, in <module>
    from flask_sqlalchemy import SQLAlchemy
  File "C:\Users\Admin\Desktop\Flask REST APIs\.venv\lib\site-packages\flask_sqlalchemy\__init__.py", line 14, in <module>
    from flask import _app_ctx_stack, abort, current_app, request
ImportError: cannot import name '_app_ctx_stack' from 'flask' (C:\Users\Admin\Desktop\Flask REST APIs\.venv\lib\site-packages\flask\__init__.py)

Usage: flask [OPTIONS] COMMAND [ARGS]...
Try 'flask --help' for help.

Error: No such command 'db'.

I have try diffence version on flask to install and uninstall but it will geting same error or diffence some things on it.

Solution

You are using versions of Flask and Flask-SQLAlchemy that are incompatible with each other. You may want to make sure that Flask, Flask-SQLAlchemy, SQLAlchemy, Flask-Migrate and Alembic are upgraded to their latest versions to eliminate incompatibilities between them.
