Angular 错误TS1005:&x27'；在使用firebase时应使用角度

因此，我试图在Angular中创建firebase推送通知的简单演示。在创建“messaging.service”并将其实现到基本组件中后，它返回我这个错误。这在我创建“messaging.service”之前不会发生。我尝试了

npm安装typescript--save dev

，但还是失败了。将我的typescript升级到其他版本时返回一个错误：angular/Complian无法对其进行重新调整

我的“messaging.service”

import {AngularFireDatabase} from 'angularfire2/database';

import * as firebase from 'firebase/app';

import 'rxjs/add/operator/take';

@Injectable({
  providedIn: 'root'
})
export class MessagingService {
  messaging = firebase.messaging();
  currentMessage = new BehaviorSubject(null);
  constructor(private db: AngularFireDatabase, private afAuth: AngularFireAuth) { }

  private updateToken(token) {
    this.afAuth.authState.take(1).subscribe(user => {
      if (!user) {
        return;
      }
      const data = { [user.uid]: token };
      this.db.object('fcmTokens/').update(data);
    });
  }

  getPermission() {
    Notification.requestPermission()
      .then(() => {
        console.log('Notify permission granted.');
        return this.messaging.getToken();
      }).then(token => {
        console.log(token);
        this.updateToken(token);
      })
      .catch((err) => {
        console.log('Unable to get permission.', err);
      });
  }

  receiveMessage() {
    this.messaging.onMessage((payload) => {
      console.log("Message received. ", payload);
      this.currentMessage.next(payload);
    });
  }
}

你知道密码在哪里断了吗？我指的是哪一行。据说“节点模块/firebase/index.d.ts中的错误”
