Hi, After encountering problems with an installation of NodeJS 20, I thought I'd do it properly this time: install NodeJS first, then Node-RED. Unfortunately, the installation script removes the existing version and reinstalls an older version of NodeJS 20. Is there a way to make the script ignore …

What does this show? which node Run sudo apt remove nodejs then check it is gone node -v The script should have removed it, but it may be that there is a problem doing that. In which case the above commands may show it.

indeed - the latest version of the script should explicitly test for dfsg versions and remove them in favour of nodesource ones. but yes - adding --node20 or --node22 to the end of the install command should force it to install a suitable version. If I use --node20 locally I get v20.19.6 which is…

I've now installed the script with NodeJS 22 without any problems. NPM: 10.9.2. With NodeJS 20, the aforementioned problem occurs on Trixies own NodeJS 20. I don't feel confident enough to manually install Node-RED with: sudo npm install -g --unsafe-perm node-red. That would leave me with an outd…

I would never recommend using a Linux distro's own repositories for node.js, they will often be outdated. Either use Dave's script or use the dedicated node.js repository for your OS. Noting that I believe Dave's script uses the dedicated repository for Debian/Rabian/Ubuntu.

you really don't want to use the default repository for nodejs - it always (IMHO) ends up causing issues - either well behind - or doesn't include npm - or occasionally (as in this instance) appears to be ahead, but includes other weird side packages... Much better to let our install script try to c…

[image] Becker: I thought I'd do it properly this time: install NodeJS first, then Node-RED. I think you are following bad advice. On a raspberry Pi install the OS, update it then use Dave's script to install npm and Node-red. I am not sure what version of node.js it installs by default, bu…

I think you (all) did not understand the problem. [image] jbudd: On a raspberry Pi install the OS, update it then use Dave's script to install npm and Node-red. That's exactly what I've always done, but with Trixie there are problems as described above. after Node-Red script has finished an…

What I see (on a Pi Zero2, 64 bit OS with Node-red 5 beta) Before: $ node-red --version Node-RED v5.0.0-beta.1 Node.js v24.11.1 Linux 6.12.47+rpt-rpi-v8 arm64 LE $ sudo apt update && sudo apt -y full-upgrade ... 3 packages can be upgraded. Run 'apt list --upgradable' to see them. Warning: https:/…
