Update, unable to connect.

[sdetweil]

@Richard238 unable to connect is because MM is not running

next time for upgrade use my script… it checks and upgrades node/npm/pm2 if needed as well as other stuff…

https://github.com/sdetweil/MagicMirror_scripts

short fix,
a. run my upgrade script with force instead of apply
or
b. upgrade node js to 16.x (will probably be 16.20)
then do npm install again

[Richard238]

@sdetweil

Option ‘a’ fixed it, thank you.

With it working, do I need to update node?

[sdetweil]

@Richard238 no, the script did that for you already

on a command line do

node -v

[Richard238]

@sdetweil

pi@magicmirror:~/MagicMirror $ node -v
v16.1.0

[Richard238]

Same issue today. Tried with force but still no MM.

node -v = v22.14.0

[sdetweil]

@Richard238 can you show the startup messages

This seems to indicate that there is an error in config/config.js. Run the following on the command line in the ~/MagicMirror/ directory: npm run config:check

@Richard238 did the

npm install 

complete?

do this

pm2 stop all
cd ~/MagicMirror 
rm -rf node_modules
npm install

the start MagicMirror manually

npm start

@Richard238 of course you dont need to do npm start if the other stuff fsiled

cd ~/MagicMirror 
rm package-lock.json 
rm -rf node_modules 
npm cache clean --force
npm install

let me know the results

[Richard238]

@sdetweil

Pi (Pi4 in metal heat-sink case) was running really warm. Powered it off and left it for a while.

Powered on, it has no networking and file manager does nothing.
If I can get networking enabled, I’ll make a config and CSS backup.

Looks like it’s going to need an OS reinstall which will have to wait until I have time to do so.
I’ll report back when that’s done.

[sdetweil]

@Richard238 my backup also gets the module source url for every add on module, so that they can be reinstalled again
and gets files created (like access tokens etc) which may be needed to make each module work

[Richard238]

@sdetweil

I couldn’t use that as I the Pi had no network, no file manager. It was bricked :(

New OS, new default vanilla MM all good.

And then I remembered the orig MM was still on a SD Card before I swapped over to a USB drive.
Copied all I needed, seems to be all good so far!

Thanks for your help. :)

[sdetweil]

@Richard238 awesome… thanks for the feedback…

@sdetweil

Hahhahaaaa! Yes, well I do make regular backups of config and CSS, it was the modules folder I was missing. Lesson learned there.
