I installed node-red-contrib-gpio and want to uninstall it. The pallette manager said it was in use but there were no nodes using it. I tried deleting the two config nodes firmata and ioplugin. Still can't remove it. Now when I start node-red I get:
5 Mar 17:46:00 - [info] Flows file : /home/pi/.node-red/flows_raspberrypi.json
5 Mar 17:46:00 - [info] Server now running at http://127.0.0.1:1880/
5 Mar 17:46:00 - [info] Starting flows
5 Mar 17:46:00 - [info] [ioplugin:850be4f5.f2df88] error loading io class
1614984360299 Available Firmata
5 Mar 17:46:00 - [info] Started flows
5 Mar 17:46:00 - [error] [ioplugin:45e03009.9ea36] Error: Error: No such file or directory, cannot open /dev/ttyACM0
Any suggestions would be welcome. I have tried using admin. Same result. I tried stop and start in safe mode. Same result.
Thanks,
Tom
