标签: angular firebase angularfire2

app.component:

           import { AngularFireModule } from '@angular/fire';
            import { AngularFirestoreModule } from 'angularfire2/firestore';
            import { RoomComponent } from './component/room/room.component';
            import { AngularFireAuth } from '@angular/fire/auth';
           import { FirebaseService } from "./service/firebase.service";
           import { AngularFireAuthModule } from 'angularfire2/auth';


   imports: [
                BrowserModule,
   AngularFireModule.initializeApp(firebaseconfig),
   AngularFirestoreModule    
  ],
 providers: [
FirebaseService,
{
  provide: PERFECT_SCROLLBAR_CONFIG,
  useValue: DEFAULT_PERFECT_SCROLLBAR_CONFIG
},
AngularFireAuth
 ],

package.json文件:

{
"dependencies": {
  "@angular/animations": "^5.2.11",
 "@angular/cdk": "^5.2.4",
"@angular/common": "^5.2.0",
"@angular/compiler": "^5.2.0",

"@angular/language-service": "^5.2.0",
"ts-node": "~4.1.0",
"tslint": "~5.9.1",
"typescript": "~2.5.3"
}
}

在服务中无效的导入:

  import { AngularFirestore, AngularFirestoreCollection, 
   AngularFirestoreDocument } from 'angularfire2/firestore';
   import { AngularFireAuth } from '@angular/fire/auth';
   import { auth } from 'firebase/app'
   import { Observable } from 'rxjs';

我只包括了可能与错误有关的依赖项,但是如果我错过了某些事情,请告诉我。

我已经尝试了多个版本。确实可以,但是有错误。问题出在导入{auth}中,这使我可以登录到Firebase。我不知道问题是什么。有时会编译,有时则不会。这是我到目前为止使用的唯一一个版本组合,有时即使有错误也可以编译。其他版本只会破坏其他导入。

仅当我暂时删除auth导入然后将其放回然后保存时,项目才会编译。

在您的app.module.ts中:

我将从大文件开始,我只是说尝试删除您的node_modules文件夹和package-lock.json,然后重新运行命令npm install。最重要的是,一些建议...

app.component(app.module?)

您的导入和文件不一致,我看到您从angularfire2以及@angular/fire导入。尽管它们实际上是同一回事,但仅仅是Angular团队正在迁移/迁移到@angular/fire。运行npm uninstall angularfire2,然后运行npm i @angular/fire。最后,您应该这样更新您的app.component(我想您的意思是app.module)……

import { AngularFireModule } from '@angular/fire';
import { AngularFirestoreModule } from '@angular/fire/firestore';
import { RoomComponent } from './component/room/room.component';
import { AngularFireAuth } from '@angular/fire/auth';
import { FirebaseService } from "./service/firebase.service";
import { AngularFireAuthModule } from '@angular/fire/auth';


imports: [
  BrowserModule,
  AngularFireModule.initializeApp(firebaseconfig),
  AngularFirestoreModule,
  AngularFireAuthModule // IMPORT THE AUTH MODULE IF YOU'RE GOING TO USE IT
],
  providers: [
    FirebaseService,
    {
      provide: PERFECT_SCROLLBAR_CONFIG,
      useValue: DEFAULT_PERFECT_SCROLLBAR_CONFIG
    },
    // AngularFireAuth (don't need/should not provide this, allow the module to set this up)
  ],

请记住,如果您有回购协议,并且希望我查看我可以提供更多帮助,我希望能够看到更多代码,但是希望这将是一个很好的开始/修复。 / p>
