      Hey everyone,

      I did a fresh, clean install using the automated script and on first time startup, MM worked with the default modules. Then I tried adding MMM-DailyXKCD and on restarting, I found that something went wrong. I’m only presented with a fullscreen black window titled “electron”, but apart from that, nothing ever happens. This is the terminal output when launching from there:

      pi@raspberrypi:~/MagicMirror $ DISPLAY=:0 npm start
      
      > magicmirror@2.9.0 start /home/pi/MagicMirror
      > sh run-start.sh
      
      Starting MagicMirror: v2.9.0
      Loading config ...
      Loading module helpers ...
      WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module 'node_helper'

      MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
      If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
      Launching application.
      
      

      Any ideas as to what’s happening here?

        @dankerthrone said in Black Screen: "cannot find module 'node_helper'":

        Cannot find module ‘node_helper’

        u did an npm install in a folder that had no package.json file I think

        workaround do

        cd ~/MagicMiror
        git checkout modules/node_modules/node_helper/index.js

          So I feel slightly stupid, but for anyone in a similar situation, @sdetweil helped @JorickJuh in this thread with the same problem. I don’t know how to hotlink replies, so for anyone wondering, @sdetweil suggested that, as is evident from the log, node_helper is missing. So, for me, this did the trick:

          cd ~/MagicMirror
          git checkout modules/node_modules/node_helper/index.js
          

          EDIT: you beat me to it :D - thanks again!
