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

photoblog@ serve C:\Kasia\Angular2 first project\photo_blog webpack-dev-server --config config/develop.config.js --inline --progress --port 8080 70% 3/3 build modules events.js:160 throw er; // Unhandled 'error' event ^

You have another server running on the same port/address (The "EADDRINUSE", 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.

I restarted my PC and it worked. I had open terminal in Visual Studio. I didn't have another terminal open.

Thanks for your answer :)
