Using commit (latest?) : 312a55c

When trying to use RoadRecon w/ Python 3.9 on Debian 11
Might be similar issue to #49

Traceback (most recent call last):

AttributeError: module 'sqlalchemy.orm' has no attribute 'DeclarativeBase'

Installing flask-sqlalchemy manually solved it for some reason:
pip3 install flask-sqlalchemy

I've pushed some updates to the minimum requirements which should prevent this. As you said, cause was likely some incompatible modules being installed.
