AttributeError: '_FakeStack' object has no attribute '__ident_func__'Update Flask-SQLAlchemy and you are good (2.4.0 -> 2.5.1)
following commands should do the trick
pip install --upgrade flask-sqlalchemy
pip install --upgrade flask-appbuilder
i used another fresh new virtual environment and installed flask-appbuilder and mysqlclient then works fine. not sure why sometimes in other environments pip install -U not report error but cannot run.
