MM not loading after software update

[sdetweil]

@Redicaljk how did you update?

[Redicaljk]

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

@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:
