Question

我有一个Angular 8应用程序，使用npm包Angular Firebase（https://github.com/angular/angularfire2），当我使用Angular CLI命令ng build --prod构建应用程序并将其部署到主机上时，我得到了以下Chrome浏览器控制台错误：

TypeError: Object(...)(...).auth is not a function

如果我改用命令ng build --prod --optimization=false进行构建，则不会发生错误。

将Angular CLI ng构建选项optimization设置为true时，会导致AngularFire2 npm软件包错误。

我不确定如何进一步调试此问题。这是我的package.json文件：

这是我导入AngularFire2库的地方：

import { Injectable } from '@angular/core';
import { AngularFireAuth } from "@angular/fire/auth";
import { Observable } from 'rxjs';
import { tap, map, take } from 'rxjs/operators';
import { Router } from '@angular/router';
import { User, auth } from 'firebase/app';

@Injectable({
  providedIn: 'root'
})
export class AuthService {
  user: Observable<User>

  constructor(
    private firBase: AngularFireAuth,
    private router: Router // Inject Firebase auth service
  ) {
    this.user = this.firBase.authState;
  }

  isLoggedIn(redirectUrl: string, isLoggedInRedirect?: string): Observable<boolean> {
    console.log('AuthService.isLoggedIn'); return this.user.pipe(
      take(1),
      map(authState => !!authState),
      tap(authenticated => {
        if (!authenticated) {
          console.log('user not authenticated');
          this.router.navigate([redirectUrl]);
          return;
        }
        console.log('user Authenticated');
        if (isLoggedInRedirect) {
          this.router.navigate([isLoggedInRedirect]);
        }
      })
    );
  }

  getDisplayName(): string {
    return this.firBase.auth.currentUser.displayName;
  }

  // Sign up with email/password
  async signUp(email: string, password: string) {
    try {
      const result = await this.firBase.auth.createUserWithEmailAndPassword(email, password);
      console.log("successfully registered!");
      console.log(result.user);
    }
    catch (error) {
      console.error(error.message);
    }
  }

  // Sign in with email/password
  async signIn(email: string, password: string, rememberMe: boolean): Promise<string> {
    let session = 'session'; //only persist in the current session or tab, and will be cleared when the tab or window in which the user authenticated is closed

    if (rememberMe) {
      session = 'local'; //state will be persisted even when the browser window is closed or the activity
    }

    console.log('persistence type', session);
    try {
      const _ = await this.firBase.auth.setPersistence(session);
      const result = await this.firBase.auth.signInWithEmailAndPassword(email, password);
      console.log('signin success');
      return 'success';
    }
    catch (error) {
      console.error(error.message);
      return error.message;
    }
  }

  async signOut() {
    try {
      const _ = await this.firBase.auth.signOut();
      this.user = this.firBase.authState;
      console.log('signOut complete, currentUser', this.firBase.auth.currentUser);
    }
    catch (error) {
      console.error(error.message);
    }
  }

  async forgotPassword(email: string): Promise<string> {
    try {
      await this.firBase.auth.sendPasswordResetEmail(email);
      return 'Reset Email Sent';
    }
    catch (error) {
      console.error(error.message);
      return error.message;
    }
  }
}

这是我的app.module：

import { NgModule, ErrorHandler } from '@angular/core';
import { RouterModule } from '@angular/router';
import { BrowserModule, HAMMER_GESTURE_CONFIG } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { GestureConfig } from '@angular/material';
import {
  PerfectScrollbarModule,
  PERFECT_SCROLLBAR_CONFIG,
  PerfectScrollbarConfigInterface
} from 'ngx-perfect-scrollbar';


import { InMemoryWebApiModule } from 'angular-in-memory-web-api';
import { InMemoryDataService } from './shared/inmemory-db/inmemory-db.service';

import { rootRouterConfig } from './app.routing';
import { SharedModule } from './shared/shared.module';
import { AppComponent } from './app.component';

import { HttpClient, HttpClientModule } from '@angular/common/http';
import { TranslateModule, TranslateLoader } from '@ngx-translate/core';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';
import { ErrorHandlerService } from './shared/services/error-handler.service';
import { SessionsModule } from './views/sessions/sessions.module';

import { AngularFireModule } from '@angular/fire';
//import { AngularFirestoreModule } from '@angular/fire/firestore';
import { environment } from '../environments/environment';
import { StartComponent } from './start.component';

// AoT requires an exported function for factories
export function HttpLoaderFactory(httpClient: HttpClient) {
  return new TranslateHttpLoader(httpClient);
}

const DEFAULT_PERFECT_SCROLLBAR_CONFIG: PerfectScrollbarConfigInterface = {
  suppressScrollX: true
};

@NgModule({
  imports: [
    SessionsModule,
    BrowserModule,
    BrowserAnimationsModule,
    SharedModule,
    AngularFireModule.initializeApp(environment.firebase),
    //AngularFirestoreModule,
    HttpClientModule,
    PerfectScrollbarModule,
    TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: HttpLoaderFactory,
        deps: [HttpClient]
      }
    }),
    InMemoryWebApiModule.forRoot(InMemoryDataService, { passThruUnknownUrl: true }),
    RouterModule.forRoot(rootRouterConfig, { useHash: true, enableTracing: false })
  ],
  declarations: [AppComponent, StartComponent],
  providers: [
    { provide: ErrorHandler, useClass: ErrorHandlerService },
    { provide: HAMMER_GESTURE_CONFIG, useClass: GestureConfig },
    { provide: PERFECT_SCROLLBAR_CONFIG, useValue: DEFAULT_PERFECT_SCROLLBAR_CONFIG }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Answer 1

这不是完整的答案，而只是我的研究。我要放在这里，希望能对某人有所帮助。

选中此命令

node --max-old-space-size=8000 ./node_modules/@angular/cli/bin/ng build --prod --aot=false --optimization=true --sourceMap=false --buildOptimizer=false

评论：可以请你！删除AOT标志还是将其设置为假？

参考：   https://github.com/angular/angular-cli/issues/14666#issuecomment-507057022

buildOptimizer不再起作用

--buildOptimizer=false

参考：   https://github.com/angular/angular-cli/issues/10658#issuecomment-387296781

--source-map生成的应用程序缩小10％

将目标设置为es5，建立目标es2015会遇到这些问题

Answer 2

根据@jamesdaniels的回答this

npm install rxjs@6 rxjs-compat@6 --save

它解决了这个问题。

这是您的解决方案Credit @Biswajit

Answer 3

通过错误导入我在组件上使用的firebase依赖项来解决此问题，您可以执行以下操作：

import * as firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/storage';
import 'firebase/firestore';
import { environment } from '../../../environments/environment';

constructor(
    private afAuth: AngularFireAuth,
    private afFirestore: AngularFirestore,
    private afStorage: AngularFireStorage
  ) {
    try {
      firebase.app();
    } catch (err) {
      firebase.initializeApp(environment.firebaseConfig);
    }
}

别忘了将Firebase配置放在您的环境文件中

Answer 4

我有同样的问题。回到

"@angular/fire": "~5.1.0",

解决了该问题，尽管有一些关于版本与其他软件包不兼容的警告（没有编译或运行时错误）。

Answer 5

AngularFireFunctions遇到相同的问题。通过将AngularFireFunctionsModule添加到我的app.module.ts中来解决该问题。只需为您的产品构建打开sourceMaps，即可调试实际损坏的库。事实证明，如果没有该模块，一切都将在开发中正常运行，但是当您使用--prod标志优化器进行构建时，它会删除部分代码，而该代码本不应删除，并且还有松散的结局。

Answer 6

就我而言，因为我在应用程序中同时使用了AngularFireAuthModule和AngularFirestoreModule，所以它们在app.module.ts中起作用了。

imports: [
    ...
    AngularFireAuthModule,
    AngularFirestoreModule,
    ...],

仅当ng服务--prod
