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:

After working on the config file for the whole day it suddenly wouldn’t start anymore.

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

[maddinmirror]

@Sean Thank you so much. That worked and it’s running again!

@maddinmirror Glad you managed to get it working again. Can you mark the post as Solved if you are happy with the solution?
