Mirror is blank even after preparing a config.js file

taztrk

Hi. I’m kind of new to ubuntu based operating systems and completely new to magic mirror and javascript. I prepared a config file based on the sample and the module information. When checked to see what the webpage looked like, there was the screen saying that i hadnt prepared a config file or that it had errors. So i did as advised and used jslint.com to debug the code until there were no more warnings. Now when I open the server page all i get is a blank screen. I think it might have something to do with the “there are no functions” phrase in the function report section of the jslint site but I have no clue. Could someone point me in the right direction please? Thanks

@taztrk make sure to check your web inspector (use the node serveronly function and a browser of your choice - there should be a thread about that somewhere) for errors.

I tried to follow the HOw to Troubleshoot forum. I downloaded firebug and did node serveronly and this is the result:

pi@raspberrypi:/var/www/html/MagicMirror $ node serveronly
module.js:440
    throw err;
    ^

I opened MM on firefox and used firebug but i didn´t see anything that looked like an error.

@taztrk so you did not do npm install?

@taztrk please use Markdown on code snippets so it is easier to read :)
Looks like your OS or node version is not supported by Electron. Try using Raspbian especially if you do not have much experience.
