I am getting the same error!
No response found yet?!

[ERROR] An error occurred while running subprocess ionic-app-scripts.

    ionic-app-scripts build --prod --target cordova --platform android exited with exit code 3.

    Re-running this command with the --verbose flag may provide more information.

Please take a look at this thread: Ionic info is not showing cordova platform. One user gave as solution “cordova globally not installed”. In my case, a re-install of 3 plugins fixed the problem. Might be worth trying for your environment!

I’ve got this issue since I updated to ionic version 4 yesterday. I can’t even use $ ionic. Is there any solution.

5

are you using fcm plugin?? Because it generally occurs when using FCM plugin.

I need to work on new project so I start ionic and I cant even start.

try to remove platform and re-add it.

I’m getting this error whenever I type ionic or ionic -v or ionic info. Any ideas on what’s going on? I have ionic@4.1.2 but it was happening with ionic@4.2.1 as well.
