Essentially what it says on the tin, I have been setting up on a raspi4 and was looking to update the Magic Mirror got a bit mixed up and ended wiping the SD card and starting again.
Now when I try and start-up following the installation instructions per the documentation (which has changed since the last time I did it, it was a single line installation before I believe) I am throwing an error based around npm when I cd into /MagicMirror “npm install” doesn’t last for as long as it says it should and then when I try “npm start” it throws the error that is seen here:

> magicmirror@2.13.0 start /home/pi/MagicMirror
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

sh: 1: ./node_modules/.bin/electron: not found
npm ERR! code ELIFECYCLE

.

I have wiped and redone this twice to double I wasn’t just failing to copy paste a couple of lines into the terminal but the problem is persisting.

As you can see it’s something to do with the Magic Mirror files themselves missing electron but I’ve just been cloning straight from the repo so I’m a bit stuck. Any ideas? Is there a step I’m missing from the documentation?

Thanks for your time,
