Vue.js npm run dev error with vue-cli

Problem:- On running the npm run dev, command after installing vue-cli, following error is thrown?
Starting dev server…
      throw er; // Unhandled ‘error’ event

Error: listen EADDRINUSE :::8080
    at Object.exports._errnoException (util.js:1026:11)
    at exports._exceptionWithHostPort (util.js:1049:20)
    at Server._listen2 (net.js:1262:14)
    at listen (net.js:1298:10)
    at Server.listen (net.js:1376:9)….

From above error we can get an hint “listen EADDRINUSE :::8080”,
issue is our port 8080 is already used, thus vue server is NOT getting started.

Easy solution, just change the port in /config/index.js file

  dev: {
    env: require(‘./dev.env’),
    port: 8082,
    autoOpenBrowser: true, 

Re-run the app again and it’ll launch without any error on new port
