Missing dependency on ionic 4

[alphasldiallo]

Same as the previous issue (#7). I tried on ionic 4, for more details: `Ionic:

ionic (Ionic CLI) : 4.9.0 (/usr/local/lib/node_modules/ionic)
Ionic Framework : @ionic/angular 4.0.0
@angular-devkit/build-angular : 0.12.3
@angular-devkit/schematics : 7.2.3
@angular/cli : 7.2.3
@ionic/angular-toolkit : 1.2.3

System:
NodeJS : v10.15.0 (/usr/local/bin/node)
npm : 6.4.1
OS : macOS Mojave`

How to reproduce

Start a blank project with Ionic CLI:
ionic start myProject

Go in myProject directory and follow the Matchmore npm installation instructions as described in README:
npm install @matchmore/matchmore --save

Edit src/app/app.component.ts to add matchmore as described in README:

import { Platform } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { Manager } from "@matchmore/matchmore";

import { HomePage } from '../pages/home/home';
@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  rootPage:any = HomePage;
  manager: any;

  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      statusBar.styleDefault();
      splashScreen.hide();
        this.manager = new Manager(
          "<Your api key>"
        )
    });
  }
}

Start ionic with: ionic serve

Then use the minimum config, like specified in the documentation:

  "<Your api key>"
)````
After saving or building, it fails to compile and it shows this error:
