Hi @Mykle1 i get this error when i make

npm start

Error:

Whoops! There was an uncaught exception...

edit:
with

sudo netstat -lnptu

i saw that electron.js is already using the port. But i have a blank screen and nothing is shown. Also rebooted a couple of times.

Hmm, make sure you only have 1 terminal open when you run npm start from the pi@user/MagicMirror directory. Also, make sure the address: "0.0.0.0", entry in your config is OUTSIDE the whitelist. If you’re running pm2 make sure that is not launching an instance of MM. Otherwise, is there anything else that you changed after the install?

How do you apply after each module you try out? Is there a way or do you have to reboot every time?

You don’t have to reboot the Pi to launch MM after adding a module. Assuming you quit MM before you added the module, you simply launch MM as you normally would

The MM autostarts when booting up the Pi, what’s the command you use to apply/run the config.js right after you save it?

When the mirror is running, press your Alt key to drop down a menu bar. Choose Minimize from the Window menu. Assuming pm2 is autostarting for you, open a terminal and type pm2 stop mm to quit MM.

You can start MM after saving your config in the terminal by typing pm2 start mm, or if MM is still running, from the drop down menu, View, Reload

The problem was the module watchdog !
Also with fresh install it throws errors with the newest update.

Fixed for me. Thank you @Mykle1 !!!

I don’t know if this is the right place for me to reply but I’m desperate.
I’m supposed to do a project for school with the MM but I can’t even seem to get it up and running.
I made an issue on the forum but so far I’ve gotten no replies :(

I followed these steps to reinstall the MM but instead of making my own config file I used the one provided. When I run it, the screen is black and I can see in dev tools that the “moment” npm package is having some issues but I can’t find any info anywhere on how to solve it or anyone that has a similar issue.

I see that you have fixed your issue in another topic. Very good! Can I ask, are you saying you had this issue after a manual installation? The symptoms and fix you used are commonly associated with the automatic installer or version update. I’m just curious because I have not heard of this happening after a manual installation.
