General
1

Hi all
after some hours of installing and settings an older RPi 3B - with Buster 10.13 (I need update NR due to new Dashboard2) have som troubles and questions after doing info from system :
pi@raspberrypi:~ $ npm -v
10.8.2
pi@raspberrypi:~ $ node -v
v18.20.8
pi@raspberrypi:~ $ node-red -h
Node-RED v4.1.1

But in the NR flows window is still version 2.1.3 ...... why ??
Have you anybody answer ?

Thanks a lot for your time. Bohumil.

debian.org: "Buster also has benefited from Long Term Support (LTS) until 30th June, 2024."

nodejs.org: " Node.js 18 and all earlier versions are End-Of-Life."

Have you considered building your system from scratch instead of trying to get outdated versions to work?

I understand it, but, how is possible to upgrade all it to completely new, in the case of, anything must going without longer drop-out. This is impossible, I think.
Well ... is not very easy, to solve it.
Only take a new RPi4 or 5 and completely do this and after completion in short time change the RPi's.
Based on this, there is no question, if is possible to change it to anything new, there is a question, what is happened, if the versions are different and how is possible to solve my first post.

Have you restarted Node-RED since installing Node-RED 4.1.1?

Assuming it's running as a service you will need to run something like:

sudo service nodered restart

(or you could just reboot the pi)

The current version of Raspberry Pi OS (Not Buster, not Bookworm but Trixie) runs on the Pi 3 and others. I have 64 bit Trixie on a Zero 2.

So you don't actually need to buy a Pi 4 or 5. If you happen to have a spare Pi 3 you can build your system on it and eventually just swap the SD card over. Downtime ~30 sec?

@hardillb yes, of course. I have restarted whole Pi. But still the same.

@jbudd mmm, OK, I think, I will do it. But, will be little bit slowly, to setup completely and some things will be out of order during whole phase of process. OK, I will try it.
At this moment I don't have any other spare Pi3B.
