typescript – Angular2 beta.12和RxJs 5 beta.3的可观察错误

你好,

我正在使用VS2015中运行的Angular2 beta 12.当我将rxjs从5.0.0-beta.2更新到beta.3时,我会遇到一系列与我的承诺有关的例外情况.

例如.

> Observable< Response>类型上不存在属性映射
> Observable< Response>类型中不存在属性共享
> Ambient模块声明不能指定相对模块名称
> Ambient模块不能嵌套在其他模块或名称空间中.

的package.json

{
  "name": "ASP.NET","version": "0.0.0","scripts": {
    "tsc": "tsc","tsc:w": "tsc -w","lite": "lite-server","start": "concurrent \"npm run tsc:w\" \"npm run lite\" "
  },"dependencies": {
    "angular2": "2.0.0-beta.12","systemjs": "0.19.24","es6-promise": "3.1.2","es6-shim": "0.35.0","reflect-Metadata": "0.1.3","rxjs": "5.0.0-beta.3",// beta.2 allowed project to build
    "zone.js":"0.6.6"
  },"devDependencies": {
    "gulp": "3.9.1","gulp-concat": "2.6.0","gulp-cssmin": "0.1.7","gulp-uglify": "1.5.3","rimraf": "2.2.8","concurrently": "2.0.0","lite-server": "2.1.0","typescript": "1.8.9"
  }
}

问题与此代码中的地图功能有关：

import {Injectable} from 'angular2/core';
import {Http,Response} from 'angular2/http';
import {Headers,RequestOptions} from 'angular2/http';
import {Observable}     from 'rxjs/Observable';

import {ApplicationVM} from '../../Applications/viewmodels/Application.viewmodel';

@Injectable()
export class applicationservice {
    constructor(private http: Http) { }

    private _serviceUrl = './../api/';

    getApplications() {
        return this.http.get(this._serviceUrl + "applications/active")
            .map(res => <ApplicationVM[]>res.json())
           // .map((res: Response) => res.json())
            .do(data => console.log(data)) // eyeball results in the console
            .catch(this.handleError);
    }

    private handleError(error: Response) {
        console.log(error);
        return Observable.throw(error.json().error || 'Server error');
    }

}

在另一个,问题是与share()

constructor(private _http: Http) {
     console.log("constructor");
     this.menulist$= new Observable(observer => this._menulistObserver = observer).share();
     this.menuState$= new Observable(observer => this._menuStateObserver = observer).share();
     this.menuWidth$= new Observable(observer => this._menuWidthObserver = observer).share();}

我觉得这可能很重要 – 一系列rxjs文件为相对引用加下划线红色../../Observable(以下示例在interval.d.ts中)

import { IntervalObservable } from '../../observable/IntervalObservable';
declare module '../../Observable' {
    namespace Observable {
        let interval: typeof IntervalObservable.create;
    }
}

我的boot.ts

///<reference path="./../node_modules/angular2/typings/browser.d.ts"/>
import {bootstrap}      from 'angular2/platform/browser';
import {ROUTER_PROVIDERS} from 'angular2/router';
import {AppComponent} from './app.component';
import {HTTP_PROVIDERS}    from 'angular2/http';
import 'rxjs/Rx'; // kitchen sink

// Bootstrap the application and reference the required directives
bootstrap(AppComponent,[ROUTER_PROVIDERS,HTTP_PROVIDERS]);

我的html页面

<!-- 1. Load libraries -->
    <script src="~/nodelibs/angular2/bundles/angular2-polyfills.js"></script>
    <script src="~/nodelibs/systemjs/system.src.js"></script>
    <script src="~/nodelibs/typescript/lib/typescript.js"></script>
    <script src="~/nodelibs/rxjs/bundles/Rx.js"></script>

    <script src="~/nodelibs/angular2/bundles/router.dev.js"></script>
    <script src="~/nodelibs/angular2/bundles/http.dev.js"></script>


    <!-- 2. Configure SystemJS -->
    <script>

    var rootPath = "@Url.Content("~/")";

    System.config({
        //transpiler: 'typescript',//typescriptOptions: { emitDecoratorMetadata: true },baseURL: rootPath,defaultJSExtensions: true,packages: {
            app: {
                //format: 'register',defaultExtension: 'js'
            },map: {

                'rxjs/observable/*' : 'nodelibs/rxjs/observable/*.js','rxjs/operators/*' : 'nodelibs/rxjs/operators/*.js','rxjs/*' : 'nodelibs/rxjs/*.js'
            }
        }
    });
    System.import("/app/boot.js")
          .then(null,console.error.bind(console));

    </script>

我很难过,并会感激一些帮助.

谢谢,丹.

根据Angular的package.json,你应该使用RxJS 5.0.0-beta.2 https://github.com/angular/angular/blob/master/package.json#L37
