Hi! I am getting this error when I run npm run serve... What I can do with that?

56,413 PointsYou have another server running on the same port/address (The "EADDRINUSE 127.0.0.1:8080", is Error, Address In Use), and if you ran the same command before that server could very well still be running. If you go to localhost:8080 in your web browser does it show you that project you're working on or something else? Do you have other terminal windows/tabs open? (if you find something running use Ctrl+D to stop it) Try hunting down the process in Task Manager and end it. And, as a last resort, reboot.

1,300 PointsI restarted my PC and it worked. I had open terminal in Visual Studio. I didn't have another terminal open.
Thanks for your answer :)
