there is no Platforms in your project try to add a platform(android ,ios) after that execute this command:
ionic cordova run android --prod

Hi,

Faced similar issues even updating the packages and all other attempts. I was in a hurry that time and finally took the release build using

ionic cordova build android --release instead of --prod.

You can get the output in this way

Thank you , i can use cordova build android --prod successful too,but i want use ionic cordova build android --prod ,beacause the diffrent effects

Tried that too. But the production build showed just a blank screen after splash and app didn’t worked well. That’s why I recommend you to go with release build

Build --prod will create a smaller app and faster to boot up
Build --release will create a production app for store (Android -> not debuggable, more security, …)

So you cannot replace prod by release you need both on your final application.

Now the real question is: how to make build prod working again …
