npm start dev

ostfilinchen

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?

@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

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

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?

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. :/

@shavesophere said in npm start dev:

Not true. It can be started over SSH just fine: DISPLAY=:0 npm start

@KirAsh4 sorry - i stand corrected! but that being said when i first started getting npm ERRS i tried this and it still did not work… anyway, moving forward now!
