Starting MagicMirror with `DISPLAY=:0 npm start` throws ERR!



  • Hi all:

    I have been at unsuccessfully for several days now and I can’t seem to get it to work. I googled and searched this forum to no avail so I am asking finally for help.

    I installed MM2 using the one liner curl installation script on a brand new Raspbian ‘Stretch lite’ installed Raspberry Pi 3.

    The install script runs fine but when I get to the point where I should start the MM2 by running the command DISPLAY=:0 npm start I get the following error:

    > magicmirror@2.2.2 start /home/pi/MagicMirror
    > sh run-start.sh

    I am not sure what’s not working and how to further troubleshoot. Anyone any ideas?

    Thanks

  • @loonix You might check to see that run-start.sh is executable:

    chmod +x ~/MagicMirror/run-start.sh
    

    You can also try :

    npm cache clean
    npm install
    npm start
    

    Finally, the MM project doesn’t run well on Raspbian Lite. Jessie Full is the recommended build. Check out this thread for a few other tips.



  • Follow my post HERE to update nodejs and requirements.

    In addition you should really consider updating your distro to Raspbian Stretch (full), and

    1. Don’t install MM as root
    2. Don’t install outside /home/pi

    But by all means, please try the lite first, and let us know any dependency issues.



  • Thank you so much ninjabreadman and e3v3a for pointing me in the right direction. With the info the both of you provided I was able to get MM2 working on my Raspberry 3 running Stretch Lite.

    Installing updated node.js as per https://www.raspberrypi.org/forums/viewtopic.php?f=34&t=140747&p=1256048#p1256048 and following this guide https://github.com/MichMich/MagicMirror/wiki/Jessie-Lite-Installation-Guide were the keys to success.

    Only thing left is that I wasn’t able to disable the sceensaver yet.

    Next steps are to try to get it to run on a Pi 0 W and get touch functionality added to my mirror.

    Thanks again
