You need to install this: Run below command line in CLI

npm i rxjs@6 rxjs-compat@6 promise-polyfill --save

Then import these libs to your home.ts:

import { Observable } from 'rxjs';
import 'rxjs/add/operator/map';

I'm using the rxjs-etc library and I was getting conflicts for some reason that not only caused the error TypeError: Object(…) is not a function but also absolutely killed my CPU in Chrome.

I'm not exactly sure why - it's related to a recent rxjs version being incompatible as far as I can tell - but if you're using this library it can be a cause of this.

if you are getting after installing any new plugin in ionic 3

then just check the version of statusbar or splashscreen plugin in package.json file

  "@ionic-native/splash-screen": "~4.17.0",
  "@ionic-native/status-bar": "~4.17.0",

and change the version of your installed plugin to same and do

npm update

it will look like this 

    "@ionic-native/camera": "^4.17.0",
    "@ionic-native/core": "~4.17.0",
    "@ionic-native/splash-screen": "~4.17.0",
    "@ionic-native/status-bar": "~4.17.0",

Hope it helps someone ...... worked for me for android permission and camera plugin

also, you will need to remove ngx from import statement

import { Camera, CameraOptions } from '@ionic-native/camera';

Though my issue isn't related to angularfire but searching for TypeError: Object(…) is not a function brings users to this question. My issue was that I was using Youtube Video Player plugin in ionic v3. But as ionic v3 docs are now auto redirected to ionic v4 docs I was using the latest version of the plugin.

just install version 4 of Youtube Video Player plugin and you are good to go.

npm install --save @ionic-native/youtube-video-player@4

Ionic v3 docs

P.S: when you are auto redirected to v4 docs of ionic just insert v3 in the URL.

This works for me, using "angularfire2": "^5.0.0-rc.11"

npm i rxjs@6 rxjs-compat@6 promise-polyfill --save

To retrieve the data:

this.db.list('/customers').valueChanges().subscribe((datas) => { 
  console.log("datas", datas)
},(err)=>{
   console.log("probleme : ", err)
});

Or you can check the GitHub repository for angularfire2 here for more details

Even though you can run rxjs-compat, its only a matter of time before you need to change your code to reflect the new RXJS. If you are using Angular 6 and the Angular 6 CLI, then you will have RXJS 6, since Angular depends on RXJS for most things. Also if you plan on using Angular Material 2, then you will need Angular 6. So lets just update your RXJS. This will be really important as of Ionic 4. Ionic 4 will depend highly on angular as it will now include the Angular Routes.

Some of the most common changes of RXJS 6 is:

import 'rxjs/add/observable/of';
// or 
import { of } from 'rxjs/observable/of';

Becomes

import { of } from 'rxjs';

and 

import 'rxjs/add/operator/map';
import 'rxjs/add/operator/take';

becomes

import { map, take } from 'rxjs/operators';

and

import { Observable } from 'rxjs/Observable';
import { Subject } from 'rxjs/Subject';

becomes

import { Observable, Subject } from 'rxjs';

Recent releases of AngularFire require rxjs 6. Please upgrade rxjs, you'll need to include rxjs-compat if you have dependencies that haven't yet upgraded.
