 I believe @paviro is the Electron God around here. But he’s busy with school at the moment so it may be a bit before he responds.

 Hi, Same error for me (Raspberry Pi 3 / Jessie) Thanks 
- 
 as I c, you’ve installed your MagicMirror in the /root directory. 
 I’m not sure if this is working so far.Try to install everything as pi and not as root in the /home/pi directory and let us know what happend. try whoami-> piupdate your distribution with sudo apt-get update && sudo apt-get upgradethen cd /home/pior onlycdand install again: curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh | bash
