sudo wget http://node-arm.herokuapp.com/node_latest_armhf.deb sudo dpkg -i node_latest_armhf.deb sudo apt-get install npm

My problem:
I made fresh installation of whole magic mirror about 2 weeks ago because I had a problem with screen size - have huge black part of screen which is “covering” right modules.
I tried electronOptions, modifiyng the /boot/config.txt and without luck.
I am running 2.4.1 on fresh installation of Stretch Lite

Off the top of my head: Did you copy the config.js.sample into config.js?

IIRC, the “EADDRINUSE” error is usually when you have an instance running and try to run the mirror without shutting down the existing NPM process.

This: bash: /home/pi/start.sh: Permission denied makes me think you need to make your start.sh script executable. Try this command: chmod a+x /home/pi/start.sh and then reboot.
