TypeScript 错误找不到模块 'angularfire2/interfaces' ionic 3 angularfire2-offline

Question

当我想设置 angularfire2-offline 时，我得到这个错误:

[16:02:08]  typescript: node_modules/angularfire2-offline/database/database.d.ts, line: 2 
            Cannot find module 'angularfire2/interfaces'. 

       L1:  import { AngularFireDatabase } from 'angularfire2/database';
       L2:  import { FirebaseListFactoryOpts, FirebaseObjectFactoryOpts } from 'angularfire2/interfaces';
       L3:  import { AfoListObservable } from './list/afo-list-observable';

[16:02:08]  typescript: node_modules/angularfire2-offline/database/interfaces.d.ts, line: 1 
            Cannot find module 'angularfire2/interfaces'. 

       L1:  import { FirebaseListFactoryOpts } from 'angularfire2/interfaces';

       L1:  import { FirebaseListFactoryOpts } from 'angularfire2/interfaces';
       L2:  export declare class EmulateQuery {

app.module.ts 中的

@ngModule:

@NgModule({
  declarations: [
    MyApp,
    HomePage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
    AngularFireModule.initializeApp(firebaseConfig),
    AngularFireDatabaseModule,
    AngularFireOfflineModule
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

版本:

• ionic 3.9.2
• 命令行界面 3.8
• angularfire2 4.0.0
• angularfire2-离线4.2.4
• Firebase 4.3.0
• typescript 2.6.0

我正在学习这两个教程:

突然出现错误。

Answer 1

好像是angularfire2新版本的问题

angularfire2 : 4.0.0-rc.2

我降级到以前的版本，现在一切正常。

npm install angularfire2@4.0.0-rc0
