/angularfire2 /索引沒有出口成員 'AngularFire'

Question

無法修復這個問題：

app.component.ts

import { AngularFire, AuthProviders, AuthMethods } from 'angularfire2'; 

/angularfire2/index has no exported member 'AngularFire', 
/angularfire2/index has no exported member 'AuthProviders', 
/angularfire2/index has no exported member 'AuthMethods ' 

但app.module.ts

import { AngularFireModule } from 'angularfire2'; 

正常工作，我可以初始化應用程序

package.json

"angularfire2": "^4.0.0-rc.0", 
"core-js": "^2.4.1", 
"firebase": "^3.9.0", 
... 
"devDependencies": {... 
"ts-node": "~2.0.0", 
"tslint": "~4.5.0", 
"typescript": "~2.2.0" 

Answer 1

由於您使用的是angularfire2@4.0.0+，因此不會再輸出AngularFire。相反，你應該使用它，如下：

// import AngularFireAuthModule at NgModule 
import { AngularFireAuthModule } from 'angularfire2/auth'; 


import { AngularFireAuth } from 'angularfire2/auth'; 
// inject 
construstor(afa: AngularFireAuth) { 
    afa.auth.signInWithPopup() 
} 

Answer 2

升級到AngularFire2 4.0解決我的問題
