I was able to get MM setup but then when I upgraded Node I’m now receiving the following error when doing

sudo npm start

Here is the error that is returned after I run this via Remote Desktop terminal

pi@raspberrypi:~ $ cd MagicMirror
pi@raspberrypi:~/MagicMirror $ sudo npm start

magicmirror@2.7.1 start /home/pi/MagicMirror
sh run-start.sh
