Magic Mirror only shows black screen

[maddinmirror]

Hey,
i’m fairly new to the scene. After working on the config file for the whole day it suddenly wouldn’t start anymore. No config file error. Just a black screen.

I ran my config file through: https://esprima.org/demo/validate.html
and it said valid.

pi@raspberrypi:~ $ cd ~/MagicMirror
pi@raspberrypi:~/MagicMirror $ npm start

> magicmirror@2.8.0 start /home/pi/MagicMirror
> sh run-start.sh

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.
Shutting down server...

Can anyone tell me why the file can’t be read
Thanks

@maddinmirror
Can you post your config? Make sure all private key or calendar links are removed or changed (xxx) before posting.

@maddinmirror So, a few things. Is this a fresh install? Did you run npm install in the MagicMirror after the install? Can you do a shit+ctrl+i to open the developer console? Select the Console Tab and scroll up and look for any errors usually marked in red.

@maddinmirror said in Magic Mirror only shows black screen:

Undo you’re changes to the config.js file to the point where it was last working.

Here are a few things to do.

• Check if the Server is still running
  • On the Raspberry Pi open a browser and visit localhost:8080 If you see a black screen the server is still running which is good…
• Check your changes with git status. Any changes that you didn’t make on purpose? (Especially check the updatenotification module Validate them and revert them if needed
• Rename your config _config.js (Or someting…) to force the MagicMirror to load the default config.js, check if the expected config file error appears
• Meditate over your changes you might miss an obvious error in your code
• Post the censored config.js file here

Your MM has been missing modules/node_modules/node_helper/index.js. (I don’t know why)
You can copy https://github.com/MichMich/MagicMirror/blob/master/modules/node_modules/node_helper/index.js then paste it as new file and save it to MagicMirror/modules/node_modules/node_helper/index.js.

Or reinstall MM.

@Sean u meant node_helper/index.js
Right?

[A Former User]

@sdetweil yes. Sorry. my mistypo.

[sdetweil]

So the correct path is

MagicMirror/node_modules/node_helper/index.js

[A Former User]

@sdetweil corrected. Thanks. :D
