[solved] npm start error

I’ve been experiencing trouble trying to start up the MM software on my Pi 3 + monitor. When I ssh into the pi and run npm start, I get the following error:

pi@raspberrypi:~/MagicMirror $ npm start

> magicmirror@2.1.2 start /home/pi/MagicMirror
> sh run-start.sh

Some things I have tried:

I tried using DISPLAY:=0 npm start when using ssh, but the same error occurred
Rather than ssh into the pi, I opened up a terminal on the jessie gui and tried the same thing. I didn’t get any errors, but I got a black screen that said All. This happened with both variations of the npm start command.
running npm update before npm start still yielded the same error
running npm install in ~/MagicMirror/vendor didn’t work

Something else worth noting is that whenever the pi starts up, I see the MagicMirror start screen that says booting up, but then I’m prompted to log into the jessie OS. Also, running npm install, and npm install --unsafe-perm both yields the following output:

pi@raspberrypi:~/MagicMirror $ npm install

> magicmirror@2.1.2 install /home/pi/MagicMirror
> cd vendor && npm install


> magicmirror@2.1.2 postinstall /home/pi/MagicMirror
> sh installers/postinstall/postinstall.sh

MagicMirror installation successful!
npm WARN stylelint-config-recommended@1.0.0 requires a peer of stylelint@^8.0.0 but none was installed.
npm WARN stylelint-config-standard@17.0.0 requires a peer of stylelint@^8.0.0 but none was installed.

I was looking at this post from 3 months ago since it seemed like the same problem I am having. Someone had mentioned that updating the node had gotten rid of some of the errors, but I’m not sure how to do that or whether that’s different than running npm update. But regardless, the failed at start script message still popped up in that post. I’m at a loss at this point

Update 1: I reinstalled the MM package from scratch, and the previous error from using ssh has gone away, but I still see a blank screen with “All” in the corner. This is the output from the terminal:

pi@raspberrypi:~/MagicMirror $ npm start

> magicmirror@2.1.2 start /home/pi/MagicMirror
> sh run-start.sh

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
Launching application.

Update 2: Using npm start via ssh doesn’t throw the “Failed at the magicmirror@2.1.2 start script ‘sh run-start.sh’.” error unless I already booted up the pi manually.

@t3xastoast So apparently changing the port from 8080 to 8000 in the config.js fixed this. It works now.
