node-red-node-pi-gpio pins stopped

Which node are you reporting an issue on?

node-red-node-pi-gpio

What are the steps to reproduce?

Import this flow and in my case the pins are in the "stopped" state. Also when trying to switch, the debug says: nrgpio python command not running

What happens?

All pins, after deploying the flow are in the stopped state. I cannot switch a pin from 0 to 1.
debug says nrgpio python command not running

What do you expect to happen?

The pins should not be in a stopped state.
I've tried the manual installation and the instructions in the forums https://discourse.nodered.org/t/node-red-node-pi-gpio-output-stopped/38363/4 and https://discourse.nodered.org/t/rpi-gpio-input-node-stopped/5184/8 to no avail.

Please tell us about your environment:

• Node-RED version: 1.2.7
• node.js version: 10.23.2
• npm version: (sorry, connection just got broken while working headless, will report asap)
• Platform/OS: Raspbian Buster
• Browser: Chromium

Start with the node-red-node-pi-gpio entry point and reproduce the supplied flow on the listed Node-RED, Node.js, and Raspbian versions. Trace why the nrgpio Python command is not running and verify that the GPIO nodes leave the stopped state and switch pins as expected.
