Also, I tried starting it using npm start; the mirror worked fine, but this is the error.
pi@raspberrypi:~/MagicMirror $ npm start

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

Inspite of this, the mirror showed me the latest news, but not the calendar. :/
