npm start dev

Hi there

I try to start my mirror whit npm start dev to do some debugging but there are always a lot of errors. What’s wrong here?

pi@raspberrypi:~/MagicMirror $ npm start dev

> magicmirror@2.0.0 start /home/pi/MagicMirror
> electron js/electron.js "dev"

Hi Bangee

I’ve had exactly the same problem. I’ve tried it on a rasp 2, a rasp 3 and still the same result. Tried reinstalling node.js, reinstalling npm. I’m beginning to think there’s something up with Mich;s installation script but I cant find any clues in the output. Apparently it’s known that sometimes electron will fail on some rasp 2’s- so i went ou t and bought a rasp 3. I’m currently trying it again on a new card - if it doesn’t work this time i’ll try the manual install method. No luck yet.

pi@magicpi:~ $ cd MagicMirror/config
pi@magicpi:~/MagicMirror/config $ cp config.js.sample config.js
pi@magicpi:~/MagicMirror/config $ cd $HOME/MagicMirror
pi@magicpi:~/MagicMirror $ npm start

> magicmirror@2.0.0 start /home/pi/MagicMirror

Hey!

in the readme i found this:

Important: npm start does not work via SSH, use DISPLAY=:0 nohup npm start & instead. This starts the mirror on the remote display.

Thanks ost - but I have tried it both from direct physical keyboard and SSH using this command. I’ve been reading a few other problems related to this issue but all seems to come down to “not installing as root user”. Which i’m not - I’m installing as pi. So still scratching my head here.

[ostfilinchen]

do you have create an mm.sh and starts this with pm2?

[shavesophere]

@ostfilinchen I was just using the standard install script that comes on the tutorial.

curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh | bash

[ostfilinchen]

and do u do these steps: https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror

[Bangee]

hey there
@ostfilinchen that’s it. to start npm from my shell it need to use this command:
DISPLAY=:0 npm start dev

But with this I can not debug my script. Electron crashes alwasy on startup when I’ve activated my new module using const sensorLib = require('node-dht-sensor') in my node_helper.js

How can I debug this error?

[shavesophere]

OK i think i’ve solved it. magic mirror HAS to be started (npm start) from a terminal window in the x-window server. you cannot start it over ssh.

@shavesophere Thank you. This at least got me to the point where I can show the display on a monitor. Now I just have to walk to the other room to see my changes. :/
