MagicMirror Failing on Raspberry Pi Zero W Rev 1.1
-
Something has gone wrong recently and I’m not sure what happened.
I had my MM unplugged for a few weeks. When I attempted to use it again, the Pi wouldn’t run MM.
I investigated and the error log shows that electron is missing. Understand that the device was working perfectly fine, then I simply unplugged the device, it sat in my backpack for a while, and then I plugged it back in.
I tried reinstalling node and a hundred other things, then just gave up and started from scratch using the same method @sdetweil and I cobbled together a few months ago.
But now that doesn’t work.Help.
Error: Cannot find module 'electron' Require stack: - /home/dvg/MagicMirror/js/electron.js at Module._resolveFilename (node:internal/modules/cjs/loader:1048:15) at Hook._require.Module.require (/usr/local/lib/node_modules/pm2/node_modules/require-in-the-middle/index.js:81:25) at require (node:internal/modules/helpers:130:18) at Object.<anonymous> (/home/dvg/MagicMirror/js/electron.js:3:18) at Module._compile (node:internal/modules/cjs/loader:1241:14) at Module._extensions..js (node:internal/modules/cjs/loader:1295:10) at Module.load (node:internal/modules/cjs/loader:1091:32) at Module._load (node:internal/modules/cjs/loader:938:12) at Object.<anonymous> (/usr/local/lib/node_modules/pm2/lib/ProcessContainerFork.js:33:23) at Module._compile (node:internal/modules/cjs/loader:1241:14) { code: 'MODULE_NOT_FOUND', requireStack: [ '/home/dvg/MagicMirror/js/electron.js' ] } -
@davidgagne Electron is not available for the pi0w, armv6l
hasn’t been for yearsmy install script configures server mode and launches a local browser over that , connected to the port from the MM config
to do this. my install script changes package.json start clause to launch a runtime script I provide (run-start.sh)
I cannot think of a way that package.json was reverted without some manual intervention
check package,json for
"start":"./run-start.sh", -
@sdetweil I’m not trying to be argumentative, but something has changed in the last two months that has caused the existing install scripts to stop working and/or caused MM to want electron.
I’m using this:
https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.shAnd then this:
https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.shExactly the way everything worked at the end of May. One of those scripts had to have changed, or the July 1 MM update has a bug. I cannot think of any other reason this isn’t working.

@sdetweil Here are the contents of the package.json and run-start.sh files. Note that I have not edited anything. This is exactly how they came from the installation process.

@sdetweil And just to be thorough, here is my install.log. I don’t know what’s going on with those weird unicode characters in the log. And there are lots of “memory leak detected” that I don’t recall seeing back in May.

@sdetweil I scoured the forums and found someone else complaining about electron being missing.
I ran this
sudo npm i -g npm@6and now it seems to be working fine. -
@davidgagne that makes no sense… the latest version of npm is 10.x
and you just installed v6… (maybe)do
npm -v
-
@davidgagne said in MagicMirror Failing on Raspberry Pi Zero W Rev 1.1:
MaxListenersExceededWarning: Possible EventEmitter memory
that is an npm bug… nothing we can do anything about. no impact on install
unicode… those are shell escape codes for color (the colors don’t show in the file, only on the actual console)
-
@sdetweil
npm -vreturns6.14.18(and it takes a solid 45 seconds to do that, which seems like a very long time for such a simple command, even on a Zero). -
@davidgagne do free -m
pi is small on memory, so running off sd card a lot…
