Hey gang,  
After a mass update of nodes, my GPIO pins are now showing **N/A: 0** and are non-operational.  
I tried to roll back to 1.2.3 with **npm install node-red-node-pi-gpio@1.2.3** but I see rollback option failed:

Any suggestions on the next step to take, please?

You are running the command from the wrong folder, you should be running it from the .node-red folder.

Before downgrading, unless you can point to a known issue with the latest version, stop node-red in a terminal and start it again and post the full terminal output here. That may allow us to identify the problem. You can stop and start using  
`node-red-stop`  
`node-red-start`

Hey Colin, thanks so much for your reply.

I've done that and this is what I get. The GPIO nodes are still showing N/A: 0

Oh boy! I just discovered that my NR version is WAAAY behind.  
I'm going to update that now and report back. Perhaps some of the updated nodes have dependencies that don't exist in v1.2.8.

Is there a way to enable auto-updates or at least get a notification when a new stable version is released?

Also updated Node.JS to 14.18.3 and installed NVM (why the heck didn't I have that before?! 🙂 )

And I'm very happy to say that my GPIO nodes are working once again. GREAT!

Once again, thanks so much, Colin. If you'd not replied, I never would have thought to check my NR version.

The problem with using nvm is that then you cannot use the usual install script for installing/updating node red and nodejs.

Ahh, interesting! So considering this RPi is used 99% for Node-RED, you'd suggest removing NVM and using the update scripts?

Also, where can I find those update scripts, please?

All the best,  
Dax.

There's a [great page on nodered.org](https://nodered.org/docs/getting-started/raspberrypi) dedicated to this topic ...
