无法将"Rx"导入我的Angular 2应用程序 [英] Unable to import 'Rx' to my Angular 2 application

问题描述

我在Angular2上还很陌生.我正在尝试使用虚拟应用程序来学习它.

I am pretty new at Angular2. I am trying to learn it using a dummy app.

我最近浏览了有关RxJS的教程，对Observables有了基本了解(或者我至少假设如此).基于此，我有一个想法，可以将正在使用的数组中的用户列表作为流返回.我打算为此使用间隔，并在屏幕上显示一种延迟加载效果.

I have recently gone through a tutorial on RxJS and got a basic hold on Observables (or atleast I assume so). Based on that, I have an idea of returning a list of users from my array in service as a stream. I intent to use interval for it and display a kind of lazy loading effect on screen.

我的意图是:

getUsers() {
        return Rx.Observable.from(this.users); //want to add interval too on this 
    }

但是，我一直坚持将"Rx"导入到我的服务中.在不导入的情况下使用"Rx"显然给我错误.其余的用于Observables和Operator的导入效果很好.

However, I am stuck at importing 'Rx' in to my service. Using 'Rx' without import obviously gives me error. The rest imports for Observables and operator works fine.

我去了node_modules，发现那里也有一个rx和一个rxjs模块.但是以某种方式使用以下任何命令，都无法摆脱Rx上的错误.

I went to node_modules and found there is a rx and a rxjs module too. But somehow using any of these below commands, I can't get rid of my error on Rx.

import 'rxjs/Rx';
import  Rx from 'rxjs/Rx';
import { Rx} from 'rx/Rx';
import { Rx} from 'rx';

我在SO上浏览了一些链接，这些链接说Rx不再与Angular捆绑在一起.但是，我正在使用最新的有角度的官方种子，并且确实看到了rx和rxjs软件包.我有package.json中提到的5.0.1版本.我在这里假设有什么问题吗?

I went through few links on SO those say Rx is no longer bundled with Angular. However, I am working with the latest angular official seed and I do see rx and rxjs packages. I have a 5.0.1 version mentioned in package.json. Am I assuming something wrong here ??

请让我知道如何使用Angular 2中的Rx创建自定义可观测对象.

Please let me know How does one work with creating custom observables using Rx in Angular 2.

注意:我在使用Http服务进行Observable返回时没有任何问题，只想使用Array从头开始创建Observable

推荐答案

在Angluar 4+中:

In angluar 4+:

import * as Rx from 'rxjs/Rx';

修复此问题后，Rxjs文档仍然是错误的.

Rxjs documentation is still wrong, after fix this.
