Python 3.7 error

[rafale77]

Attempting to rebuild home assistant on Python 3.7.5 coming from 3.6.5.
The miio component fails at startup and crashes home assistant. It was working fine on 3.6.5 with the exact same config. Home-assistant on 3.7.5 was completely rebuilt and reinstalled from scratch.

This is what I am seeing:

I did manually install the python-miio component using pip. Not sure whether this is a component issue or a config issue. All other components appear to have installed fine.

I can confirm that it is unique to python3.7. I ran the exact same config and fresh install with the same method on python 3.6.9 and had no such problem.

Confirmed error while trying to build with python3.7.5 which is apparently missing python.h

And fixed by installing python3.7-dev. which I was missing...
