Ok, Nic' has just announced the new version releases of NR. I am sticking with 4.x and have 4.0.9 Buster and NodeJS 18.20.8 How do I update? My efforts so far have yielded: node-red-stop sudo npm install -g --unsafe-perm node-red node-red --version node-red-start The version should show me 4.1…

I think you need to use... sudo npm install -g --unsafe-perm node-red@4.1.13 to get a specific version installed. If you use... sudo npm install -g --unsafe-perm node-red you will get the latest version of Node-RED which currently is 5.0.4

Not sure this is good. sudo npm install -g --unsafe-perm node-red@4.1.13 npm warn EBADENGINE Unsupported engine { npm warn EBADENGINE package: 'validate-npm-package-name@7.0.2', npm warn EBADENGINE required: { node: '^20.17.0 || >=22.9.0' }, npm warn EBADENGINE current: { node: 'v18.20.8', n…

Think I got same npm warnings when I updated, although Node-RED seems to work just fine.

Not to bait you, but if I installed NR via the normal script..... on a Pi..... Do I need the sudo? I thought NR was run as the user, not root.

Correct. You don’t need sudo with the script. It will do that for you as necessary. (but that is not what you have shown above)

Just out-of-interest - what version of OS are you running? I assume you are running on a RPi ? Older versions like Buster won't work as 32-bit support has been dropped. You really need to be running Bookworm OS.

[image] Trying_to_learn: I thought NR was run as the user, not root. It is run as user, but you need sudo to install it globally. Just like installing most other s/w on the pi. [Edit] but you don't need to use sudo with the bash script as the script adds the sudo for the required commands f…

Ignore the npm warning, you can’t use the latest npm with that outdated version of node.js. I would say that the other issue is a node-red bug because I think v4.* is supposed to be baselined against node.js v18. But, node.js v18 it’s beyond end of life. If your os supports it, you should upgrade …

ISTR from another thread his Buster OS doesn't support later nodejs due to libc/gcc changes etc...
