[ng] ERROR in node_modules/@ionic-native/firebase/index.d.ts(2,10): error TS2305: Module '"/node_modules/rxjs/Observable"' has no exported member 'Observable'.
[ng] node_modules/rxjs/Observable.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/Observable'.

npm version 6.2.0
ionic version 4.0.1

This error is caused, because when you add plugins from ionic native, it fetches that latest stable version which does not work with the latest ionic 4 beta version.
So you need to add the corresponding beta version for ionic native as well. So you need to run this:

1. npm install @ionic-native/[email protected]
2. npm install @ionic-native/[email protected]

Then other important thing is to note that for angular the import of ionic native plugins in app module also has changed, so you will have to make the following change in you app.module:

import { Firebase } from '@ionic-native/firebase/ngx';

(Note the ngx at the end, this has to be done for all native plugins from now on)

Then it should run fine. Hope this helps! 👍

@onkar0777 thanks for the update, I'm still getting a compile error. Any idea's?

[ng] ERROR in src/app/app.module.ts(8,26): error TS2307: Cannot find module '@ionic-native/firebase**/ngx**'.

[onkar0777]

I would guess that you did not run npm install @ionic-native/[email protected]

Also I am not sure what is ** in @ionic-native/firebase/ngx

As Rxjs is required for Angular 6 using in Ionic 4.
