UNSOLVED Error starting MagicMirror after an update

Major

I ran an update on my Magic Mirror last night and now it will not launch.

I get the following error:
pi@raspi-calendar:~/MagicMirror $ npm start

magicmirror@2.4.1 start /home/pi/MagicMirror
sh run-start.sh

Please help!

Thank you,

@major - It looks like electron didn’t install properly.

If you run npm install from inside the /home/pi/MagicMirror folder, it should automatically install electron. If that doesn’t work, you can install electron specifically by typing sudo npm install electron@2.0.0

I’m sorry, I didn’t report back.

Running npm install did the trick!

Thank you!
