can't run "npm run start"

jefftse

I tried both. I even deleted the whole folder and reinstalled. Maybe electron is the problem.

@jefftse no, change the line in package.json
from

 "start": "DISPLAY=\"${DISPLAY:=:0}\" ./node_modules/.bin/electron js/electron.js",

to

 "start": "./node_modules/.bin/electron js/electron.js",

the error is " cannot open display: :0.0" typically, DISPLAY:0 is the physical display

@sdetweil

just did that and the error is below

magicmirror@2.11.0 start /home/jeff/MagicMirror

@jefftse do u have a real display

jefftse

@sdetweil yes, in fact, i had it all working yesterday till I accident broken my sd card. I had to rebuild everything today.

sdetweil

@jefftse did u use my install script? can’t understand why u are having trouble

jefftse

@sdetweil sure did. I had to create an user to run your script since it wouldn’t allow me to do in root

sdetweil

@jefftse not supposed to be root
are u trying to run as root?

can’t do that
