Was working fine, now just a blank screen

  • I was making minor edits, adding modules and check all along the way, no idea what happened but now just getting a blank screen, config passes check passes;

    pi@magicmirror:~/MagicMirror $ npm run config:check
    > magicmirror@2.9.0 config:check /home/pi/MagicMirror
    > node tests/configs/check_config.js
    Checking file...  /home/pi/MagicMirror/config/config.js
    Your configuration file doesn't contain syntax errors :)

    MagicMirror-out.log file is curious;

    > magicmirror@2.9.0 start /home/pi/MagicMirror
    > sh
    Starting MagicMirror: v2.9.0
    Loading config ...
    Loading module helpers ...
    No helper found for module: alert.
    Loading module helpers ...
    No helper found for module: alert.
    Whoops! There was an uncaught exception...
    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:
    Launching application.

    Machine can definitely access the internet. The error file is obviously large, but this looks relevant, however now I am lost.

    (process:1118): Gtk-WARNING **: 20:41:00.584: Locale not supported by C library.
    	Using the fallback 'C' locale.
    WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module 'node_helper'

    You could try pressing CTRL-Shift -i after the Magic Mirror launches and provides a black screen. The Developers Window should be displayed. Then click on the Console Tab. Errors are typically listed in Red and that may help to diagnose where the issue is.
    Learned this from Sam @sdetweil .
    I personally cannot launch the Developers console on my Magic Mirror setup , but that does not mean you cant. 😉

  • @davidkmcw said in Was working fine, now just a blank screen:

    Error: Cannot find module 'node_helper

    that thing again


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

    this was caused by doing an npm install in a folder that did NOT have a package.json file

  • Had the same issue after updating a module in the remote control panel
    This did solve it, tx sdetweil
