this is what I get when executing:

➜ python_scripts python alexa_sync.py
Traceback (most recent call last):

ModuleNotFoundError: No module named 'requests'

Any ideas on what to do, @craiggenner and @imduffy15 ?

you need to install the requests module.

That said this no longer works for me after a change at Amazons end.

@craiggenner what a shame :(. We need to find a way for this work. I will research and circle back to you guys.
