MMM-Button white screen



  • Hello,

    I have installed the MMM Button. When I restart my PI3 I only get a white screen.
    When I uncomment the butten module in the config with //, the screen is after a new start normal.
    I have also tried it with a connected and unconneted butten. Always the same.

    Has anybody an idea, why I have a white screen?

  • code: ‘MODULE_NOT_FOUND’ sounds like you misspelled the module name in the config

    I checked the double checked the spelling. Everthing is correct.
    The screen stays white…

    I tried node serveronly

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



  • Solved the problem…

    I hat forgotten to install onoff (pi@raspberrypi:~/MagicMirror $ npm install onoff
    )

    That tells me you didn’t read the instructions, because step 2, under Installation, it specifically says to run 'npm install' which would’ve taken care of installing onoff for you. I find it helps when I follow the author’s instructions.

  • @KirAsh4

    I read the instruction and I executed the nmp install in the MagicMirror folder and thought that onoff would be installed automaticly.
    But I had to execute npm install onoff extra in the MagicMirror folder to get the module run.

    Maybe there should a step 3, that tells you to execute npm install onoff.

    No, the instructions, as written, are accurate. You missed the last bit of Step 1:

    1. Navigate into your MagicMirror’s modules folder and execute git clone https://github.com/ptrbld/MMM-Button.git.A new folder will appear navigate into it.
    2. Execute npm install to install the node dependencies.

    Had you done that last bit, you would be executing the next step from within the button module folder, not within the MagicMirror folder.



  • @KirAsh4
    Ahhh, okay, that´s an explanation why I have sometimes problems with some modules.

    Thank you.

    It can be a confusing, sometimes damn near frustrating landscape to maneuver. Glad you got it to work though.
