Module''*''沒有導出成員'app'

Question

我們正在離子平臺2上開發一個開源應用程序，有人將Firebase添加到項目中，並且我提出了請求，現在當我嘗試運行我獲得的應用程序時這個錯誤。這可能與某些Firebase依賴項或軟件包有關。我怎樣才能解決這個問題？

幾乎所有與Firebase相關的行都會出現此錯誤。例如：

export declare function _getAuthBackend(app: firebase.app.App): FirebaseSdkAuthBackend; 

這裏是代碼：

import * as firebase from 'firebase'; 
import { Observable } from 'rxjs/Observable'; 
export declare abstract class AuthBackend { 
    abstract authWithCustomToken(token: string): Promise<FirebaseAuthState>; 
    abstract authAnonymously(options?: any): Promise<FirebaseAuthState>; 
    abstract authWithPassword(credentials: EmailPasswordCredentials): Promise<FirebaseAuthState>; 
    abstract authWithOAuthPopup(provider: AuthProviders, options?: any): Promise<firebase.auth.UserCredential>; 
    abstract authWithOAuthRedirect(provider: AuthProviders, options?: any): Promise<void>; 
    abstract authWithOAuthToken(credentialsObj: firebase.auth.AuthCredential, options?: any): Promise<FirebaseAuthState>; 
    abstract onAuth(): Observable<FirebaseAuthState>; 
    abstract getAuth(): FirebaseAuthState; 
    abstract unauth(): Promise<void>; 
    abstract createUser(credentials: EmailPasswordCredentials): Promise<FirebaseAuthState>; 
    abstract getRedirectResult(): Observable<firebase.auth.UserCredential>; 
} 
export declare enum AuthProviders { 
    Github = 0, 
    Twitter = 1, 
    Facebook = 2, 
    Google = 3, 
    Password = 4, 
    Anonymous = 5, 
    Custom = 6, 
} 
export declare enum AuthMethods { 
    Popup = 0, 
    Redirect = 1, 
    Anonymous = 2, 
    Password = 3, 
    OAuthToken = 4, 
    CustomToken = 5, 
} 
export interface AuthConfiguration { 
    method?: AuthMethods; 
    provider?: AuthProviders; 
    scope?: string[]; 
} 
export interface FirebaseAuthState { 
    uid: string; 
    provider: AuthProviders; 
    auth: firebase.User; 
    expires?: number; 
    github?: firebase.UserInfo; 
    google?: firebase.UserInfo; 
    twitter?: firebase.UserInfo; 
    facebook?: firebase.UserInfo; 
    anonymous?: boolean; 
} 
export declare function authDataToAuthState(authData: firebase.User, providerData?: firebase.UserInfo): FirebaseAuthState; 
export declare function stripProviderId(providerId: string): string; 
export interface EmailPasswordCredentials { 
    email: string; 
    password: string; 
} 

Answer 1

任何以下配置步驟的可能會丟失。

1. 模塊中添加firebase到類型數組中tsconfig

2. 進口

   import { AngularFireModule } from 'angularfire2';  
   @NgModule({ 
       declarations: [...], 
       imports: [ 
       ..., 
       AngularFireModule.initializeApp(firebaseConfig) 
       ], 
   ... 
   

3.You可能需要運行

typings install 

注： -

const firebaseConfig = { 
    apiKey: "<your-key>", 
    authDomain: "<your-project-authdomain>", 
    databaseURL: "<your-database-URL>", 
    storageBucket: "<your-storage-bucket>" 
}
