Weird error. Is there more after the error? On first glance it looks like an error inside the lib. Maybe some lib isn't matching the pigpio lib? I will give it a try later.

You need to start the pigpio deamon which then opens the port: http://abyz.me.uk/rpi/pigpio/pigpiod.html

Seems to be a Python 3.7 issues. async became a reserved keyword which breaks upstream. Create a PR there. Hope they accept it. Otherwise we will fork it as apigpio-mpf.

I created an mpf apigpio repo here: https://github.com/missionpinball/apigpio. Will push that to pypi in a few days.
