mac_start.command Issue/Error

I have successfully installed instapy but when trying to run **mac_start.command** from instapy quickstart, I get the following:

Ivans-MacBook:~ ivan$ /Users/ivan/Downloads/instapy-quickstart-master/run/mac_start.command ; exit;
Starting InstaPy with quickstart

Any help would be appreciated!

Start by running run/mac_start.command and trace quickstart.py line 24 through the reported instapy/instapy.py and database_engine.py calls. Reproduce the NOT NULL and NoneType errors, then verify that the quickstart completes without the traceback and starts InstaPy successfully.
