当我想要离线安装angularfire2 2时，我会得到以下错误：

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

@ngModule in app.module.ts

@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：

• 离子3.9.2
• CLI 3.8
• angularfire2 4.0.0
• AngularFire2-离线4.2.4
• 火力4.3.0

我正在学习这两篇教程：

错误突然发生了。

Answer 1

这似乎是新angularfire2版本的一个问题。

angularfire2 : 4.0.0-rc.2

我对以前的版本进行了降级，现在一切都很好。

npm install angularfire2@4.0.0-rc0
