MagicMirror does not start anymore

[Chris]

Hello everyone,

I am coming to you because of a problem that I can not solve.
I rebooted my magic mirror and relaunched it. While everything was working correctly until now, it shows me a black screen.
I started this one with the command npm start dev and it shows me the following error:

pi@raspberrypi:~/MagicMirror $ npm start dev

> magicmirror@2.5.0 start /home/pi/MagicMirror
> sh run-start.sh "dev"

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
Launching application.

I made an update of my raspberry and made a npm install in the MagicMirror folder but that does not change anything.

Could someone give me a track to solve this problem?

Thanking you in advance,

Try npm install valid-url from the Magic mirror folder

Hello,

Thank you for your answer.
I tried install valid-urlbut it did not change anything.
I solved the problem using a backup of the pi that I had (thankfully) done.
I updated the pi and everything is working properly.
this bug will definitely remain a mystery …

Thank you for your help,
Regards,

@sdetweil This worked for me after my MagicMirror refused to start. Thanks!
