IONIC 2 RefrenceError：firebase沒有定義

Question

我已經拉過這段頭髮很長一段時間了。

我正在嘗試使用Facebook身份驗證的Firebase。我也初始化我的應用程序在app.module.ts 但是，當我在我的Android設備上運行下述代碼，我得到

"RefrenceError: firebase is not defined"

signInWithFacebook(){ 
    var _authInfo 

Facebook.login(['email']) 
    .then((_response) => { 
    console.log(_response) 

    _authInfo = _response 

    return this._FBUserProfile(); 

    }).then((success) => { 
    this.TEST = "IM IN"; 
    let creds = (firebase.auth.FacebookAuthProvider as any).credential(_authInfo.authResponse.accessToken) 
    let providerConfig = { 
     provider: AuthProviders.Facebook, 
     method: AuthMethods.OAuthToken, 
     remember: 'default', 
     scope: ['email'], 
    }; 
    this.af.auth.login(creds, providerConfig) 
     .then((success) => { 
     console.log("Firebase success: " + JSON.stringify(success)); 
     this. Error += (JSON.stringify(success)); 
     this.UID = success.auth.uid; 
     }) 
     .catch((error) => { 
     console.log("Firebase failure: " + JSON.stringify(error)); 
     this. Error += (JSON.stringify(error)) 
     }); 

    }) 
    .catch((_error) => { this. Error +=(_error) }) //Error caught here. 


} 



_FBUserProfile() { 

    return new Promise((resolve, reject) => { 
    Facebook.api('me?fields=id,name,email,first_name,last_name,picture.width(100).height(100).as(picture_small),picture.width(720).height(720).as(picture_large)', []) 
     .then((profileData) => { 
     console.log(JSON.stringify(profileData)); 
     return resolve(profileData); 
     }, (err) => { 
     console.log(JSON.stringify(err)); 
     return reject(err); 
     }); 
    }); 
} 

這些是我的進口。我已經在項目文件夾中運行npm install firebase angularfire2 --save

import { Injectable } from '@angular/core'; 
import { AuthProviders, AngularFireAuth, FirebaseAuthState, AuthMethods, AngularFire } from 'angularfire2'; 
import { Platform } from 'ionic-angular'; 
import { Facebook } from 'ionic-native'; 

另外，還要注意

Answer 1

您使用此：

firebase.auth.FacebookAuthProvider

，但您未導入火力點，即使你輸入angularfire你需要如果您像使用一樣使用它，請導入Firebase。

因此，嘗試添加此：

import * as firebase from 'firebase';
