Question

我想知道是否有人可以帮助我，我正在努力解决一个我在互联网上找不到任何痕迹的错误。它是“_co.auth未定义”，当我setRoot或推送到我的应用程序的主页时它被抛出。这是堆栈跟踪：

TypeError: _co.auth is undefined

以下是我称之为的函数：

constructor(private toast: ToastController, private fb: FireBaseProvider, public navCtrl: NavController, public navParams: NavParams) {
  }


  createProfile(profile: Profile){
    this.fb.createProfile(profile)
    this.toast.create({
      message: 'Profile information updated',
      duration: 3000
    }).present();
    this.navCtrl.push(HomePage);
  }

并且fb.createProfile另一端的函数是：

profile = {} as Profile;
  user = {} as User;
  constructor(private afAuth: AngularFireAuth, private afDatabase: AngularFireDatabase) {
  }

  createProfile(profile: Profile){

    this.afAuth.authState.take(1).subscribe(auth => {
      this.afDatabase.list(`profile/${auth.uid}`).push(this.profile);
      });
  }

我真的希望有人可以帮我解决这个问题因为我完全难过了！

提前致谢！
