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

@Hawking
module.js:339
throw err;

Error: Cannot find module ‘express’

and then the browser loads and says it cannot find http://localhost:8080

@SebTota I went to my old image from before the update and thats still working fine, but when I updated it, it again had the error come up. The only difference is last time I did the update it said Error: Cannot find module ‘colors’

Hawking

@SebTota
I still don’t understand what update you are referring to.
Both error messages sound like there are modules missing (either “express” or “colors”).

What happens if you do

cd ~/MagicMirror && sudo npm install
cd ~/MagicMirror/vendor && npm install

SebTota

@Hawking My MagicMirror has been sitting for a long time. When I recently finished the frame to get the computer display and rpi zero out of my closet I booted the rpi zero and on the top of the display it said A New Version of Magic Mirror is available or something along those lines. So I went into the MagicMirror folder and used the command “git pull && npm install” as specified in the README file of MagicMirror.

Hawking

@SebTota said in How I got my Magic Mirror working on a Raspberry Pi 0 (zero):

git pull && npm install

Have there been errors when you did so?

I got

npm WARN lifecycle magicmirror@2.1.1~install: cannot run in wd %s %s (wd=%s) magicmirror@2.1.1 cd vendor && npm install /home/me/MagicMirror

Thats why I then did

cd ~/MagicMirror/vendor && npm install

in addition (see my post above). Maybe this also solves your problem.

SebTota

@Hawking Sorry to keep bothering you but I ended up making it work with the two commands you told me to do. Now my problem is when the Pi Zero W is booting it connects to the WiFi but when magic mirror boots the pi disconnects.

Hawking

@SebTota
Just to make sure that I understand the problem correctly:
You see the MagicMirror on the screen (Clock running etc). but you can no longer connect to the Pi Zero (using eg. ssh)?

Just as a test:
What happens if you disable the MagicMirror from autostart (for example by moving the MagicMirror start script from /etc/init.d/ to your home directory) and start it manually while you are already logged in? I don’t know your exact setup or your Linux knowledge, if you need further help how to do this, just let me know.

SebTota

@Hawking I actually eventually got it working. Thanks so much for all your help!

Hello everyone.

I’ve followed the instructions and did everything in the comments (all 12 pages) to make sure I am doing them right. I was able to see MM2 thru the browser but on my screen, it is showing white screen.

If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

mind helping me out with this?

@hoggboss22 your mm seems being excuted multiple. Common pitfal is that more than one browser are opened.(maybe your previous test running?)
Or your machine is already using port 8080.

Kill all browsers(and node or npm) and restart. Or change port in your config like 8088.

hoggboss22

I thought the same thing, i changed from 8080 to 9090 and it gave me the same error. I ran the net stat command to find the port being in used and guess what… there was nothing that is using 8080 or 9090

Hello:) I have similar problem. Magic Mirror installed from image downloaded from this thread. Installed on piZero. Working ok. On screen there was a message to update. I did this and now MM not working. Try config with only clock. Not help.

@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.

12wsx

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.

psteimann

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

Hawking

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

This post is deleted!

12wsx

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 :-(
