Cannot find module 'undici' - 'npm install' doesn't work

Klinge

Hi,

since today my MMM don´t start.

When I start it, I got the following error message

pi@raspberrypi:~/MagicMirror $ display=:0 npm start

> magicmirror@2.30.0 start
> npm run start:x11


> magicmirror@2.30.0 start:x11
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

A JavaScript error occurred in the main process

When I try “npm install” I got the following

pi@raspberrypi:~/MagicMirror $ npm install
npm error code EBADENGINE
npm error engine Unsupported engine
npm error engine Not compatible with your version of node/npm: magicmirror@2.30.0
npm error notsup Not compatible with your version of node/npm: magicmirror@2.30.0

npm error A complete log of this run can be found in: /home/pi/.npm/_logs/2025-01-02T08_02_32_005Z-debug-0.log

So I tried to update my npm with

sudo apt update
sudo apt full-upgrade
sudo apt remove node
sudo apt remove nodejs
sudo apt install nodejs

but npm has still the version 10.8.2

So, what have I done wrong?

It would be really nice, if you have some advice for me.

Thank you in advance.

Kind regards
Klinge

@Klinge yes it says we need node 20.18.1 or above
https://forum.magicmirror.builders/topic/19271/version-2-30-0-requires-updated-nodejs-warning-for-pi0w-installations

anyhow quickest way
install tool to allow changing node versions

sudo npm install n -g
sudo n 20.18.1

now do the MagicMirror install

cd ~/MagicMirror
npm run install-mm

@Klinge also, next time use my upgrade script

Klinge

@sdetweil Thank you for your help.

After updating to 20.18.1 unfortunately I get the following error

pi@raspberrypi:~/MagicMirror $ pwd
/home/pi/MagicMirror
pi@raspberrypi:~/MagicMirror $ npm run install-mm
node: /usr/lib/arm-linux-gnueabihf/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by node)

And yes, the next time I will use your upgrade script ;-)

sdetweil

@Klinge you are on buster os… you need to upgrade to a later version, as that library is not available on buster… my script would have told you that…

use my backup/restore scripts
https://github.com/sdetweil/MagicMirror-backup-restore

to be able to quickly move to new OS

use install script to install MM on new os
https://github.com/sdetweil/MagicMirror_scripts
and then restore to put back MM config and modules

(and upgrade script next time)

Klinge

@sdetweil Shit, that’s the same problem I had with my second mirror a few weeks ago. Well, it’s been running fine since 2016.
Many thanks for your tips. With your scripts I’ll quickly install the new one.

sdetweil

@Klinge if you had started w my script it would have told you so you didn’t have to upgrade NOW . sorry

the whole objective of my scripts is to prevent this exact scenario. broke system.
