属性''类型' typeof Observable'

我正在构建一个Angular5项目,我必须使用http。我在这里使用observable,但是当我使用'

 scope.fetchApi = Observable.of(data);

然后它给了我一个错误:

Property 'of' does not exist on type 'typeof Observable'. 

我也导入了'rxjs/add/observable/of';,但同样的错误。 我也曾尝试过import { Observable } from 'rxjs/Observable';,但却抛出了错误:

Module '"eclipse:angular5-example/node_modules/rxjs/Observable"' has no exported member 'Observable'.

您可以看到我的代码如下:

import { Component, OnInit } from '@angular/core';
import { UserService } from './app.service';
import { FetchApi } from '../models/fetch-api.model';
import { Router } from '@angular/router';
import { Observable } from 'rxjs';
import  'rxjs/add/observer/of';

@Component({
  selector: 'app-fetch-api',
  templateUrl: './fetch-api.component.html',
  styleUrls: ['./fetch-api.component.css']
})
//
  export class FetchApiComponent implements OnInit {

  fetchApi: Observable<FetchApi[]>;

  constructor(private router: Router, private userService: UserService) {


  }

  ngOnInit() {
     const scope = this;
    this.userService.getUsers()
      .subscribe( data => {
         scope.fetchApi = Observable.of(data);
        //this.fetchApi = data;
      });
  };



}

请详细说明。

阅读此https://github.com/ReactiveX/rxjs/blob/master/docs_app/content/guide/v6/migration.md

导入路径已更改。

import { Observable, of } from 'rxjs';

仅返回(data)而不是Observable.of(data)
