Have I made a mistake here?
Or what is the reason?

cd ~/MagicMirror/modules/MMM-Button
sudo npm rebuild --runtime=electron --target=1.4.6 --disturl=https://atom.io/download/atom-shell --abi=50

Any Ideas? Thanks!
I’ve done everything which was postet in this topic…

Thank you.

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.

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 .

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

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
