Angular2，地產 '地圖' 上不類型存在 '可觀測'

進口：Angular2，地產 '地圖' 上不類型存在 '可觀測'

import { Component,OnInit } from '@angular/core'; 
import { FormGroup, FormControl, Validators, FormBuilder } from '@angular/forms'; 
import { Application } from './Application'; 
import { Http, Response } from '@angular/http'; 
import { NgModule } from '@angular/core'; 
import { Headers } from '@angular/http'; 
import 'rxjs/add/operator/map'; 
import 'rxjs/Rx';

的方法：

saveApplcation() { 
    var application = new Application(); 
    application.ssnr = this.form.value.ssnr; 
    application.loanamount = this.form.value.amount; 
    application.email = this.form.value.email; 
    application.phonenumber = this.form.value.phonenumber; 
    application.repaymenttime = this.form.value.time; 

    var body: string = JSON.stringify(application); 
    var headers = new Headers({ "Content-Type": "application/json" }); 

    this._http.post("api/Application/", body, { headers: headers }) 
     .map(returnData => returnData.toString()) 
     .subscribe(
     retur => { 
      this.showForm = false; 
      this.showMenu = true; 
     }, 
     error => alert(error), 
     () => console.log("done post-api/loan") 
     ); 

};

錯誤說：TS2339地產 '地圖' 上不存在鍵入'Observable'。 TypeScript虛擬項目C：\ Users \ kim \ Documents \ Visual Studio 2015 \ Projects \ NewOblig3 \ NewOblig3 \ app \ app.component.ts 52活動

我見過人們導入'rxjs/add/operator/map' ;並說它會工作，但不是在我的情況。

看起來你寫錯了：retur => {。改變它返回 – eg16

返回只是我想的一個變量。不要以爲它會影響錯誤 –
