Ionic cordova build error after install @ionic-native/firebase

I installed firebase in ionic application (Ionic Native - Firebase)

After installation, I started to give an error

@ionic-native/firebase/ngx/index.d.ts, found version 4, expected 3

I downgrade version to 3.14.0 and after the app stops building (android version)

then i run

ionic cordova build android --prod --release

or

ionic cordova run android

these errors appear in the console

It wasn`t possible to find a solution, maybe someone has encountered this problem and will help to solve it.
Thank!

I’ve same problem, have you found a solution ?

what is the android platform version u using? if u are at ionic 3 then when installing the platform android use @7 and don’t install the latest one. try reinstalling the platform and as u said u downgraded to 3 then re add ur plugins for that version of ionic as ionic 3 dont require u to add /ngx after import. also check the goodle play service version. changing version of the framework will require you to change a lot of stuff when building. hope this helps
