你好，
我正在使用在 VS2015 中运行的 Angular2 beta 12。当我将 rxjs 从 5.0.0-beta.2 更新到 beta.3 时，我遇到了一系列通常与我的承诺有关的异常。
例如
map类型上不存在属性Observable<Response>share类型中不存在属性Observable<Response>- 环境模块声明不能指定相对模块名称
- 环境模块不能嵌套在其他模块或命名空间中。
包.json

"rxjs": "5.0.0-beta.3", // beta.2 allowed project to build
"zone.js":"0.6.6"
},
"devDependencies": {
"gulp": "3.9.1",

"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');
}
}
另一方面，问题在于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 文件在红色下划线表示相对引用../../Observable（下面的示例在 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]);

}
}
});
System.import("/app/boot.js")
.then(null, console.error.bind(console));
</script>
我很难过，希望能得到一些帮助。
谢谢，丹。
