Flask Hello World Error

I'm new to Python and Flask so I'm sorry if I miss any details. When I launch PyCharm choose "New Project" and select Flask and using nothing but the defaults and try to run the pre-generated "app.py" I get this error:

FLASK_APP = app.py
FLASK_ENV = development
FLASK_DEBUG = 0

I have no idea what I did wrong. I'm on OSX 10.13.4 running PyCharm Professional 2018.1

Any help would be great!
