Solution:-
nFrom above error we can get an hint “listen EADDRINUSE :::8080”,
nissue 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
n
ndev: { env: require(‘./dev.env’),n
port: 8082,
n
n autoOpenBrowser: true,
nRe-run the app again and it’ll launch without any error on new port
