No Coding Required: Node-RED On A Raspberry Pi Opensource.com
I don't know what might cause this, but since no-one else has replied so far then possibly I can get things moving.Firstly to get your system up to date you have run sudo apt update before sudo apt full-upgrade so try that first. Then in a terminal go to your .node-red folder and runnpm install node-red-contrib-modbusif that still fails then how did you install node-red? The recommended way is using the script from -started/raspberrypi
