I can't JWT implementation for my app


I am trying implementation JWT with https://github.com/vmanchev/ionic3-seed-jwt but I didn’t able it. Last, I got that error

Uncaught TypeError: __WEBPACK_IMPORTED_MODULE_0__angular_core__.OpaqueToken is not a constructor
    at Object.<anonymous> (storage.js:230)
    at __webpack_require__ (bootstrap 1eb62cb7ba312b8c5f2e:54)

I imported these packages in app.module.ts

import {AuthHttp, AuthConfig} from 'angular2-jwt';
import {IonicStorageModule} from '@ionic/storage';
import {HttpModule, Http} from '@angular/http';
import { AuthService } from '../providers/auth-service/auth-service';

Then use this constructor in app.module.ts

export function getAuthHttp(http, storage) {
  return new AuthHttp(new AuthConfig({
    noJwtError: true,
    globalHeaders: [{'Accept': 'application/json'}],
    tokenGetter: (() => storage.get('id_token')),
  }), http);

And providers section in app.module.ts

providers: [
    { provide: 
    { provide: ErrorHandler, useClass: IonicErrorHandler },
      provide: AuthHttp,
      useFactory: getAuthHttp,
      deps: [Http, Storage]


If I try to run it on my phone I get an error like;

[20:10:38]  typescript: .../node_modules/@ionic/storage/es2015/storage.d.ts, line: 2
            '"/node_modules/@angular/core/core"' has
            no exported member 'OpaqueToken'.

       L1:  import { OpaqueToken } from '@angular/core';
       L3:   * Storage is an easy way to store key/value pairs and JSON objects.
