Error found: Error: Module version mismatch. Expected 50, got 46.

Open a terminal, change into the MMM-Button folder and run this:
npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=50

Thanks.
Now, I’m getting the below different version error.

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

please run npm list, which electron version are you running?

If it is 1.4 then please run

npm rebuild --runtime=electron --target=1.4.0 --disturl=https://atom.io/download/atom-shell --build-from-source

[titusece]

Awesome, nice hint.

pi@raspberrypi:~/MagicMirror $ 
pi@raspberrypi:~/MagicMirror $ npm list | grep electron
├─┬ electron-prebuilt@1.4.5
│ ├─┬ electron-download@3.0.1
npm ERR! peer dep missing: grunt@~0.4.0, required by grunt-yamllint@0.2.0
pi@raspberrypi:~/MagicMirror $

I did this and no more problem now.

npm rebuild --runtime=electron --target=1.4.5 --disturl=https://atom.io/download/atom-shell --abi=50

Thanks much. :)

My Problem is:
Error: Module version mismatch. Expected 50, got 51.
NOT: Expected 50, got 46

Hello, i have another version of electron:

pi@raspberrypi:~/MagicMirror $ npm list | grep electron
├─┬ electron-prebuilt@1.4.6
│ ├─┬ electron-download@3.0.1
npm ERR! extraneous: stylelint@7.5.0 /home/pi/MagicMirror/node_modules/stylelint

What must be done here?

npm rebuild --runtime=electron --target=1.4.6 --disturl=https://atom.io/download/atom-shell --abi=50

Is that ok???

[titusece]

Yes, you can do like that to fix the problem.

Thank you
