How to start/stop node-red? (and a bit more)

Colin · 14 March 2025 09:16

What do these commands show?
which node
which npm
apt policy nodejs
apt policy npm

It is not a problem, ignore it.

jbudd · 14 March 2025 09:16

Don't worry, we all get that.

It is kind of the ...... main machine.

I guess I could update it, but.......

I'd have to remember all the stuff I've got installed on it and install them on the new build.
(Not the end of the world.)

I updated form ...... jessie to buster a few years ago.

Trying_to_learn · 14 March 2025 09:22

(just mentioning)

Everything was working and I was editing code in a subflow.

DEPLOY..... (wait wait wait)..... no response from server.

Colin · 14 March 2025 09:26

The details are important when entering commands

jbudd · 14 March 2025 09:27

Yup, been there, done that. I still have one Pi running Bullseye.
Probably best to concentrate on NR just now.

There was a time when you had to install npm seperately but I think that was back at Wheezy.

"Everything was working" Hmm something broke, let's hope it's not the SD card failing.

Stepping back while Colin diagnoses...

Trying_to_learn · 14 March 2025 09:30

I hope the SD card isn't on it's way out.

Haven't had any other problems. I was just .... stupidly ..... trying to get a bit of code working.

Colin · 14 March 2025 09:33

Did you see my last post?

Trying_to_learn · 14 March 2025 09:34

Yes, but I do not know what it means.

So wasn't sure if it was a question or statement.

Colin · 14 March 2025 09:36

I posted

You mistyped the third one.

Trying_to_learn · 14 March 2025 09:39

Sorry.

Finger nails are long.

I slightly changed the order only that they are

which node
which npm
apt policy npm
apt policy nodejs

Only that their outputs are small to large.

It was only the one you mistyped originally that we needed.

That all looks ok, what about
node -v
npm -v

Make sure all your os packages are up to date
sudo apt update && sudo apt full-upgrade

Then try the -v commands again.

I realise it isn't that, nodejs 18 is the latest supported for buster, so re-run the script but with --node18 instead of 20

Trying_to_learn · 14 March 2025 09:51

It's down to the Install Node.js 18 LTS line....

Wow! Done. Moving to next line.

Installing core now.

DONE....

Try running it now?

Or copy the files back first?

Colin · 14 March 2025 09:54

Don't you keep image backups of all your SD cards? If not then you should. Then when one fails you just need to re-burn it on a new card.

Colin · 14 March 2025 09:56

Try it, run
node-red-start
