[INFO] Waiting for connectivity with ionic-app-scripts...

Description: I installed new ionic cli release, and since i’m unable to run application. The message stop at “[app-scripts] [09:08:10] lint finished in 1.48 s” and then continue to output “Waiting for connectivity with ionic-app-scripts”. If I stop the build with ctrl + c and try to rerun again, i get error : [app-scripts] Error: listen EADDRINUSE :::53703 [app-scripts] at Object.exports._errnoException (util.js:1020:11) [app-scripts] at exports._exceptionWithHostPort (util.js:1043:20) [app-scripts] at Server._listen2 (net.js:1258:14) [app-scripts] at listen (net.js:1294:10) [app-scripts] at net.js:1404:9 [app-scripts] at _combinedTickCallback (internal/process/next_tick.js:83:11) [app-scripts] at process._tickCallback (internal/process/next_tick.js:104:9) [app-scripts] at Module.runMain (module.js:606:11) [app-scripts] at run (bootstrap_node.js:389:7) [app-scripts] at startup (bootstrap_node.js:149:9) I get this error until I close the terminal, try to run again, get “Waiting for connectivity”, same loop.
