Here am using rxjs 7.4.0 only. but still it says error

Answer 1

I think this error was already reported here . The problem is that you are trying to use RxJS 7 but Ionic Native needs RxJS 5.5 or 6.5.

From the error message, looks like you're using @ionic-native/core@5.36.0 and according to the CHANGELOG this issue was fixed in 5.36.1 , so the easiest way to fix this would be to update your package.json file to use the 5.36.1 version of ionic/native / awesome-cordova-plugins .
