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

sdetweil

@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.

Klinge

@sdetweil Yes, you’re absolutely right, of course. Sometimes you have to learn from your own mistakes ;-) so we just call it a Layer8 problem ;-) Thanks anyway for your effort

Hi,
@sdetweil some minutes ago I updated my MMM with your script

kling@raspi-mm-gaeste:~/MagicMirror $ bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)" apply
update log will be in /home/kling/MagicMirror/installers/upgrade.log

After that I tried to start my MMM and now I got the same error message "Cannot find module ‘undici’.

So my question again, what did I wrong? It is necessary to install the MMM completely new?

Thank you.

Kind regards.

@Klinge you tried to do it manually , my script will NOT upgrade OVER the same version accidentally

local version 2.30.0 already same as master 2.30.0

so you have to FORCE it

change the update command string end from
apply
to
force

Klinge

@sdetweil Great, now it works.

Thank you for your help again
