ReferenceError：Rxが定義されていません

Question

私はangle2の学習を始めました。私はangular2を使ってRxJのサンプルを作成しようとしています。それは非常に、いくつかの人が私を助けていただければ幸いです。

RxJsコード -

var obs = Rx.Observable.interval(500) 
     .take(5) 
     .do(i => console.log(i)); 

package.json

{ 
    "name": "angular-quickstart",

Answer 1

私はちょうど観測前のRxを取り出して、それが魅力のように働いています。

var obs = Observable.interval(500) 
    .take(5) 
    .do(i => console.log(i)); 

Answer 2

1. NPMインストールrxjs

counter.ts

import {Observable} from 'rxjs/Observable'; 
import 'rxjs/add/observable/interval'; 

// To get the typescript compiler to recognise Rx.* execute. 
// npm install @types/rx --save-dev 

let obs = Observable.interval(1000); 


obs.subscribe(value => console.log("Subscriber: " + value)); 

1. TSCのcounter.ts

2. ノードカウンタ。 js
