MM not loading after software update

[Redicaljk]

@sdetweil I clicked on Install Updates from the notification in the Task Bar.

[sdetweil]

@Redicaljk MagicMirror does not update that way, only system stuff.

but maybe node/npm changed
.can u show results of

node -v
npm -v

[Redicaljk]

@sdetweil sorry, I am a complete newbie. I tried entering node-v and npm-v in the terminal and I get “command not found”.

[sdetweil]

@Redicaljk there is a space between node and -v

[Redicaljk]

@sdetweil thank you!
pi@rpi4:~ $ node -v
v16.17.0
pi@rpi4:~ $ npm -v
8.15.0
pi@rpi4:~ $

@Redicaljk ok, lets redo the npm install for MagicMirror

cd ~/MagicMirror
rm -rf node_modules
rm package-lock.json
npm install --omit=dev

[Redicaljk]

@sdetweil done. Still having an issue:

@Redicaljk see this topic, for missing libraries

https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later, 1st post gives instructions

[Redicaljk]

@sdetweil thank you! I’ll give it a try.

[Redicaljk]

@Redicaljk Looks like the original issue has been resolved, however, MM still crashes. I can’t copy the error without this post being marked as spam!!!

[sdetweil]

@Redicaljk send to me in email…
same userid at gmail

[sdetweil]

@Redicaljk did some other module need a library?

[Redicaljk]

@sdetweil just emailed you.

[sdetweil]

@Redicaljk looking at it

[sdetweil]

@Redicaljk workaround, do

cd ~/MagicMirror
nano package.json

scroll down to the line that looks like this

		"start": "DISPLAY=\"${DISPLAY:=:0}\" ./node_modules/.bin/electron js/electron.js",

change to look like this

		"start": "DISPLAY=\"${DISPLAY:=:0}\" ./node_modules/.bin/electron --no-sandbox js/electron.js",

ctrl-o
to save the changed file
ctrl-x to exit nano

then npm start to test

[sdetweil]

@Redicaljk see my post above

[Redicaljk]

@sdetweil Success! Thank you. MM now loads and does not crash but Weather module is not loading and there’s an error in the calendar module.

[sdetweil]

@Redicaljk show the errors, email if required

[Redicaljk]

@sdetweil just emailed you.

[sdetweil]

cd ~/MagicMirror/modules/MMM-OnThisDay
rm -rf node_modules
rm package-lock.json
npm install --omit=dev
