Raspberry Pi Zero W for Magic Mirror

[davidgagne]

@sdetweil It looks like I spoke too soon. After a reboot, I cannot seem to get any output from MagicMirror.
I rebooted and then called pm2 start MagicMirror from within the MagicMirror directory, and it seems to execute just fine. But … nothing happens. It doesn’t actually start the app, as far as I can tell. Even though the output seems the same:

Any ideas?

@davidgagne pm2 logs --lines=75

[sdetweil]

@davidgagne that circle with the arrow heading column says times restarted. 148 is a problem

[davidgagne]

@sdetweil I emailed you the output from that. I’m guessing Error: Cannot find module 'electron' is bad?

[davidgagne]

@sdetweil It’s frustrating because I swear it was working before I rebooted.

[davidgagne]

@sdetweil If you thought 148 restarts was bad … This is what I see now:

@davidgagne got it. Just back from my walk… will examine…

[davidgagne]

@sdetweil I followed your tutorial on adding the Jeopardy module (just to see what would happen) and it worked fine. The last step is npm start and when I did that I got this:

> magicmirror@2.27.0 start
> ./run-start.sh $1

@davidgagne yep,

not my tutorial just one I reference

see this

[davidgagne]

@sdetweil Hmmm. Okay. I tried that for the ‘alert’ module but it didn’t seem to have any impact:

dvg@hyperspace:~/MagicMirror $ cd modules/
dvg@hyperspace:~/MagicMirror/modules $ ls
default  MMM-JEOPARDY
dvg@hyperspace:~/MagicMirror/modules $ cd default/
dvg@hyperspace:~/MagicMirror/modules/default $ ls
alert  calendar  clock  compliments  defaultmodules.js  helloworld  newsfeed  updatenotification  utils.js  weather
dvg@hyperspace:~/MagicMirror/modules/default $ cd alert
dvg@hyperspace:~/MagicMirror/modules/default/alert $ ls package.json
ls: cannot access 'package.json': No such file or directory
dvg@hyperspace:~/MagicMirror/modules/default/alert $ npm init -y
Wrote to /home/dvg/MagicMirror/modules/default/alert/package.json:

{
  "name": "alert",
  "version": "1.0.0",
  "description": "The alert module is one of the default modules of the MagicMirror². This module displays notifications from other modules.",

  "scripts": {

  },

}

Same result; just a bunch more restarts and nothing appearing. (The Pi desktop is there, though.)
