@sdetweil

I’ve always used “npm start”. Tried starting it with both commands.

pi@raspberrypi:~/MagicMirror $ Start MagicMirror
-bash: Start: command not found
pi@raspberrypi:~/MagicMirror $ npm start

magicmirror@2.36.0 start
node --run start:wayland

/bin/sh: 1: ./node_modules/.bin/electron: not found
pi@raspberrypi:~/MagicMirror $

[sdetweil]

@Lmagenis fun times

Try

cd ~/MagicMirror 
npm install electron@41.3.0

please advise results

[Lmagenis]

@sdetweil I really appreciate your help with this!

The log has over 600 lines in it. Is there something specific to look for?

[Lmagenis]

@sdetweil
The install returned “npm error A complete log of this…”

[sdetweil]

@Lmagenis did it succeed or fail,

Without the log

[sdetweil]

@Lmagenis can you send me the log , same userid at gmail please

[sdetweil]

The log says your disk/sd card is full (or failing)

no space left on device

[Lmagenis]

@sdetweil Thank you! Looks like I have some cloning to do (once I get the new card)

[sdetweil]

@Lmagenis yes, maybe there is a bunch of log files you can delete

Then you could use my backup/restore scripts
https://github.com/sdetweil/MagicMirror-backup-restore.git

Which has a perfect use for this
Very small data. Can use GitHub too as the storage place

[Lmagenis]

@sdetweil got the new card up and running! Went through the scripts as you instructed but came up with a new error. Started the magic mirror in x11 and it works! Thanks again for your help! You’re indispensable!

[sdetweil]

@Lmagenis great news!!!

Where did you see the error ?

How did you install MagicMirror on the new system?

[Lmagenis]

@sdetweil I backed up the files with your script first in case the sd copy program in the pi failed. I didn’t need the backup, but it’s nice to have in case something goes wrong.

when I ran “npm start” it was loading the modules and returned this:

(I skipped copying the earliest info about all of the modules)

[sdetweil]

@Lmagenis ok, understood

We changed npm start to use the Wayland compositor, instead of x11 because the pi os has that as default now

If you used my install script and selected pm2, then my startup script (mm.sh) detects which compositor is running, and issues the appropriate start command
