New install - (npm run install-mm) - returns errors

Hi, brand new user and no experience with Pi programming.

Running Pi4 with 64bit new install. Pi all updated.

Following instructions (have tried 6 times) all goes well until I enter the “npm run install-mm” and each time I get the following.

leehill@raspberrypi:~/MagicMirror $ sudo npm run install-mm

magicmirror@2.29.0 install-mm
npm install --no-audit --no-fund --no-update-notifier --only=prod --omit=dev

npm error code EBADENGINE
npm error engine Unsupported engine
npm error engine Not compatible with your version of node/npm: magicmirror@2.29.0
npm error notsup Not compatible with your version of node/npm: magicmirror@2.29.0
npm error notsup Required: {“node”:“>=20.9.0 <21 || 22”}
npm error notsup Actual: {“npm”:“11.0.0”,“node”:“v23.4.0”}
npm error A complete log of this run can be found in: /root/.npm/_logs/2024-12-18T19_34_41_408Z-debug-0.log
leehill@raspberrypi:~/MagicMirror $

what am I doing wrong?? Thanks!!

yes, we don’t support node 23 until next release, Jan 1.

the 'easiest way back is

sudo npm install n -g
sudo n 22
hash -r

then start install again

Sam, you’re a genius!!! Thank you so much, been tearing my hair out with that!!

@lostagain if you had used my installer script, it would have installed the correct version of node (listed as 1st alternative install choice)

@sdetweil Good to know (I’ll remember that next time!!) thank you

@lostagain my upgrade script will do it too between releases
