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

@12wsx
Sometimes, this error seems to happen when MM is terminated abnormally. (I don’t know what is normal termination. :D)
In my case, execution npm for debug or test after first normal pm2 bootup makes this error.(Of course, before npm start dev I stopped pm2 process.)
For the solution, I change port from 8080 to 8081 or from 8081 to 8080(when I meet this problem again). It seems that after some minutes the port is freed automatically(or by execution with port changed.). And fortunately for me, first execution of MM(by pm2 on bootup) is always a success. So… I stop caring about this.

my I please someone to make an image of sd card with installed and working MM? i’m trying about week to run MM on piZero and nothing… all the time diffrent errors which i don’t understand.

@12wsx Change the Port from 8080 to 8099 and then try again…solved a lot of problems for me…

After some weeks with the MagicMirror running, my SD card got corrupted and I decided to reinstall the system from scratch. I switched from “Jessie Light” to “Stretch light”, used node 6.11.4 and of course the latest MagicMirror 2.1.3.

I can access the MM from the browser of my laptop, but Midori only shows a white page. Even for a very simple config file:

var config = {
        address: "",
        port: 8080,
        ipWhitelist: ["192.168.2.185", "127.0.0.1", "::ffff:127.0.0.1", "::1"],
        language: "en",
        units: "metric",
        modules: [
        {
                module: "helloworld",
                position: "bottom_bar",
                config: {
                        text: "Hello world!"
                }
        }
        ]

};

/*************** DO NOT EDIT THE LINE BELOW ***************/
if (typeof module !== "undefined") {module.exports = config;}

The start of MM gives no error

Starting MagicMirror: v2.1.3
Loading config ...
Loading module helpers ...
No helper found for module: helloworld.
All module helpers loaded.
Starting server on port 8080 ...
Server started ...
Sockets connected & modules started ...

Ready to go! Please point your browser to: http://localhost:8080

and if I change from

midori -e Fullscreen -a http://localhost:8080

to

midori -e Fullscreen -a http://www.google.de

I see the google page. So Midori itself and the output on screen seems working as well.

Is anybody having an idea where to search for the error?
Is anybody using MagicMirror 2.1.3 on its Pi Zero?

@Hawking same problem rpi 1

first set:
set ipWhitelist: [] to allow all IP addresses.

Warning, this enables from everywhere (on your net) have access.
then in webbrowser go to pizero ip with port set in config ex. 192.168.1.12:8080 and check if its working

don’t work for me, cannot connect to destination :-(

why he’s looking for /home/pi/package.json then it is /home/pi/MagicMirror/package.json ?

This is my log

@Doubleve
In which directory did you execute npm start
? I would assume you would first go to your MagicMirror directory (cd /home/pi/MagicMirror ). This would also explain the problem with the missing package.json file.

However, I’m not sure if npm start works at all in combination with the serveronly mode (needed for the Pi Zero). For starting, I use the method described in the first post of this thread in the section “Setting up boot scripts”.

I can acccess my MM from remote, however still didn’t get it to show in the Midori browser :-/
