      Blank black screen

      Hi,
      I have the same black screen problem. I have not added any other modules. Just have renamed the config.js.sample to config.js
      The application launches with a black screen.

      In the terminal it says
      No helper found for module: clock
      no helper found for module: complements

      When i start the console
      With npm start dev following errors are found
      Uncaught reference error: moment is not defined
      At Class.getDom (clock.js:77)
      At updateDom (main.js:99)
      at Object.updateDom (main.js:470)
      at Class.updateDom (module.js:291)
      at clock.js:45

      Need help I am stuck
      Thanks

      For the black screen problem, I even did the git pull to update
      git pull https://github.com/MichMich/MagicMirror
      From https://github.com/MichMich/MagicMirror

      branch HEAD -> FETCH_HEAD
      Already up-to-date.
      

      Now where is the issue??? Stuck please help.
      If this is the problem with the config.js file please send me a working config file. I shall try and see if it works for me.

        @dhirajv12 Seems more like you are missing some dependency. Try reinstalling from scratch…

          i tried a fresh installation with
          curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh | bash
          it shows
          shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
          but later it shows the Magic Mirror2 logo and proceeds…

          is there a problem?

              @dhirajv12 Never seen this. Googled it. Found this.
              If it works now, I wouldn’t worry too much.

                  After I found that it failed at electron. I installed it with
                  sudo npm install electron:1.6.9 -g
                  after that I did cd /MagicMirror npm start.
                  MagicMirror did pop up but with a message that if did not find the config file. So there was a sample file in?magicMirror/config folder. I remaned it to config.js from config.js.sample.
                  I ran it, then the screen went black…
                  The contents of config file looks like this…

                    @dhirajv12 I’m not really familiar with these errors. To me, it seems like you have some mismatch of versions, e.g. node being too old or too new. Did you try to update as mentioned in the output?

                        Regarding “electron@1.6.10 postinstall”: There is an issue during installation with the extract-zip package which in turn results in a postinstall problem with electron (visible sign: There is no path.txt file in the node_modules/electron folder. Starting MM gives you the error message ‘Electron failed to install correctly, please delete node_modules/electron and try installing again’).

                        As far as I understand, extract-zip is now version 1.6.4 and with this version, postinstall on electron fails.

                        This post helped: https://forum.magicmirror.builders/topic/2460/magicmirror-fails-to-install-during-electron-installation/2

                        I am still struggeling with the black blank screen (and I have to further look into this), but the electron installation can be fixed by issuing (as taken from the referenced post - actually a downgrade of the extract-zip package):

                        npm uninstall extract-zip
                        npm install extract-zip@1.6.0
                        npm install electron
                        

                        Note: I am a noob, yet… ;-)

                        Regards,
                        HerrB92
