the above information is about ionic, Cordova and my system information. I’m facing the exit 0 error while CLI serving the app script. I attached my error statement below

F:\Familybook\trunk\FabAppLatest> ionic serve

[app-scripts] [13:13:35]  ionic-app-scripts 3.2.0

[ERROR] ionic-app-scripts has unexpectedly closed (exit code 0).

        The Ionic CLI will exit. Please check any output above for error details.

I’m having the same issue, I’ve tried reinstalling everything from different versions and nothing has worked so far. I even tried installing everything on a fresh computer but still had no luck.

I don’t know if this will help you but I was able to get rid of the error by accessing an old restore point (11th October 2018) and then uninstalling nodejs, removing npm and npm-cache from AppData. Then reinstalling a slightly old version of nodejs (v8.11.4) and reinstalling ionic and cordova with
npm i ionic cordova -g

Hope this helps!
