The error you're getting is in a dependency package, sysv-ipc which has started using Python 3.6+ syntax, so you should install the previous version of that before you start:

sudo pip3 install sysv-ipc==1.0.1
sudo pip3 install adafruit-circuitpython-rfm9x

[bennuttall]

Actually that won't work because Blinka requires sysv-ipc==1.1.0: https://github.com/adafruit/Adafruit_Blinka/blob/master/requirements.txt#L6

In fact Blinka requires Python 3.6+: https://github.com/adafruit/Adafruit_Blinka/blob/master/setup.py#L44

I think if you upgraded your pip it would honour the "Requires-Python" specification and tell you it's not possible to install. You need to start using Buster and Python 3.7 to get this to work.

Upgrading to Raspbian Buster with the accompanying python 3.7.3 works. THX!
