Errors trying to run MM on Pi3



  • Help! I’m a complete noob trying to go through the installation tutorial. https://forum.magicmirror.builders/topic/236/complete-setup-tutorial/6 but it’s complaining about node install.js I tried updating npm but still get this:

    magicmirror@2.1.3 start /home/pi/MagicMirror
    sh run-start.sh

    run-start.sh: 4: run-start.sh: electron: not found
    npm ERR! file sh
    npm ERR! code ELIFECYCLE
    npm ERR! errno ENOENT
    npm ERR! syscall spawn
    npm ERR! magicmirror@2.1.3 start: sh run-start.sh
    npm ERR! spawn ENOENT
    npm ERR!
    npm ERR! Failed at the magicmirror@2.1.3 start script.
    npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

    npm ERR! A complete log of this run can be found in:
    npm ERR! /home/pi/.npm/_logs/2018-01-01T01_22_06_331Z-debug.log

    Any suggestions in extremely plain English very welcome. Thanks and happy New Year.



  • @Esinem It seems that you do not have Electron installed on your Pi. If you install electron, it should overcome that error.

    First, go to your home directory: cd ~
    Then install electron: npm install electron@1.4.15
    Once that is complete, try starting the mirror again.

    Good luck!

    NOTE: This won’t work (see below). Instead cd ~/MagicMirror.



  • Thanks but it didn’t seem to work 😞 I tried what you said and then continued with the steps in the tutorial but as you can see it failed. I tried running it again but more errors.

    I’m off to bang my head on a wall! 🙂 I’m quite prepared to believe I’m doing something idiotic as I’m a total Pi/Raspbrian/Python virgin.

  • @Esinem you installed it in /home/pi instead of /home/pi/MagicMirror



  • @strawberry-3.141 Thanks. Isn’t that what I was told to do or am I completely misunderstanding things?

    First, go to your home directory: cd ~
    Then install electron: npm install electron@1.4.15

    I think I need to study some very basic tutorials before I even try to install stuff!



  • @Esinem its a dependency of magicmirror so it should be installed in the magicmirror directory or globally. Try cd ~/MagicMirror and then the install command again



  • Aha! Many thanks. We seem to be getting somewhere now but not out of the woods yet. MM loads, which is a result, and I get a black screen with a little drop-down with options like full screen, properties, session info but no data displayed. Something flashed up fast as it loaded which I think indicated it couldn’t find something. Helper module? I’m not sure it’s relevant as I see some modules don’t have helper files

    I had errors relating to electron@1.17.10 so tried installing that but no change.

    Here’s my screen: https://photos.app.goo.gl/4Qbew2OasrjvqhWH2 Doh! Just figured out the drop down is to do with VNC not MM.

    I ran dev and I can see the line with config.js is highlighted. It tested without syntax errors. I appreciate sample stuff needs localising but should the clone of the sample show something or do I need to make any changes to display anything?



  • Hurrah!! I found a post dated 3 days ago by Lange which solved it:

    npm install --unsafe-perm

    Thanks for your input.
