cant get magicmirror to show up on screen

yo-less

What information comes up when you enter “pm2 logs mm” in the terminal window?

I get a whole bunch of errors, but the output tells me that I either have wrong versions of nodejs or npm or the magicmirror package itself is the one to blame. After that comes the message that electron js/electron.js fails
Here is the log file that need to be submitted according to the log output:

Ok, there might be a problem with your electron installation.
Can you go into your MagicMirror folder and type “node serveronly”?

Then, go back to your browser window and type in “localhost:8080”

lysnikolaou

Ok it is now working.
I will now try to enable kioskmode.

This would mean that there seems to be a problem with your electron installation. Since you’ve got a Pi 3, I would try to get that fixed, it’s much easier to have the mirror act the way you want it to if the kiosk mode comes up automatically. I’m running the mirror on a Pi 1 and it took me forever to get everything set up so that the system boots into the mirror, I had to make sure the browser didn’t start too early, and so on. It requires many manual modifications and I’m almost certain that’s not the path you want to take :).

Your mirror installation is not properly set up, I would try to fix that.

I’m not sure if the problem on your system is electron or the mirror installation, as I’m not able to use electron on my Pi I have no experience with using it. But you can try going to your MagicMirror folder and typing in: “npm install electron”, this may set things right.

If it doesn’t, maybe try a reinstall.

lysnikolaou

I get an error every time. Both with npm install electron and by reinstalling the whole package. I dont get what the error is but it seems to be with nodejs.

Hm, like I said, anything I’m suggesting at this stage is purely experimental as I have no experience with setting up the MagicMirror electron environment, but you could try upgrading your node installation.

Please only do that if you are willing to set up your Pi all over again (Reinstalling Raspbian, etc.) should this fail, because it’s hardly ever a good idea to turn your system into a patchwork project.

Someone at stackexchange.com said this helped them in installing Node.js on their Pi 3:

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs 
sudo apt-get install -y build-essential

Source: http://raspberrypi.stackexchange.com/questions/45319/install-newer-node-version-on-pi-3

If you’re not willing to reinstall everything, should this compromise your Raspbian setup, I would suggest waiting for other forum members’ suggestions on how to proceed.

lysnikolaou

I had done just that, even before your post. And when i run nodejs -v it outputs v6… which is just fine. I don’t know, maybe I will reinstall raspbian and start it all over again

That might be the best way of going about it if you are only planning on using the Pi for the Magic Mirror.
Did you start out with a brand new Pi or did you install some other software on it as well?

lysnikolaou

No, only this, but I first followed wrong instructions and installed unnecessary software that might have somehow affected the other installations.
