Solution :

When I dropped sudo from sudo flask run, Flask finds $FLASK_APP. But, I got the error message socket.error as: [Errno 13] Permission denied. I can't see a way around this, as Flask cannot find $FLASK_APP when I run as superuser. 

Still I managed to run Flask by changing the port from 80 to 5000 and dropping sudo with flask run. This is running fine now. 

I was able to run flask db init after dropping and recreating my database, and removing calls to db.create_all.
