How I got my Magic Mirror working on a Raspberry Pi 0 (zero)

What does npm start do in /MagicMirror

@noorm91 npm start is the command to start the Magic Mirror application and display the interface on the screen.

I can’t seem to start MM with npm start, tried through SSH and directly on rpi with keyboard.

Thats what I expected for the Pi Zero. Did you try the method described in the first post of this thread in the section “Setting up boot scripts”?

I took everything back with the first post everything works !!!

@Doubleve
Can you tell me which Linux distribution (lsb_release -a), node version ( node -v ) and version of MM you are using?

Hi guys, I saw someone asked before, isn’t there anyone who has a working image for MM2 on a Pi Zero. I tried a lot of things before, cant get it to work. Now, I don’t have a lot of time to experiment with it, school and work are killing me. My mirror is lying around, unused. Please help me out here,
Thanks!!

Here is an image, it has a couple of errors that needs fixing but the magicmirror starts at least.
If you have any solutions please keep us informed…this image is made by Sebtota.

Any clue on what is trying to start and not functioning alright here?

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

This usually means that you already have a process trying to serve up web pages on port 8080. In my experience, this happens when you do not terminate your previous attempt to run the MM process and start up another one. The new one also tries to serve up pages on port 8080 and you get that error.

You can use ps ax | grep node to see if node is running when you attempt to start your mirror. If it is, node is already serving up pages, so you will want to stop whatever process is running first. Alternately, if you are running a web server on port 8080 already, you can switch the port of the MM process in the config.js file.
