Angular RC 1-了解订阅成功的时间

Question

自从迁移到RC1以来，我遇到了一些问题，其中一个问题在我的一个组件中，我有一个服务，它从laravel api中获取一些json并订阅它，然后在组件中我有以下

        import {Component, ElementRef, OnInit} from '@angular/core';
        import {ProjectsMainApi} from "../../../services/projects-main";
        declare var jQuery: any;
        declare var subscribe: any;
        import { RouteConfig, ROUTER_DIRECTIVES, ROUTER_PROVIDERS } from '@angular/router-deprecated';
        @Component({
            selector: 'projects',
            templateUrl: './app/components/Projects/list/index.html',
            directives: [ROUTER_DIRECTIVES]
        })
        export class ProjectsListComponent implements OnInit {
            elementRef: ElementRef;
            project: Object;
            constructor(elementRef: ElementRef, private _projectsmainapi: ProjectsMainApi) {
                this.elementRef = elementRef;
                this.project = this._projectsmainapi.project$;
                this._projectsmainapi.getProjectsMain();        
            }
            ngOnInit() {

                this.project.subscribe(() => {
                   alert('subscribed');
                });
            }
        }

不合格的部分是

                this.project.subscribe(() => {
                   alert('subscribed');
                });

在升级之前，编译器编译了这个没有问题，它工作了，但自从升级之后，我得到了这个错误TS2339:类型"Object"上不存在属性"subscribe"。

我的服务文件根本没有改变，布局如下

    import {Http, Headers, Response} from "@angular/http"
    import {Injectable} from "@angular/core"
    import {IProjectsMain} from "../interfaces/IProjectsMain"
    import 'rxjs/Rx';
    import {Observable} from 'rxjs/Observable';
    import {Observer} from 'rxjs/Observer';
    import 'rxjs/add/operator/share';
    import 'rxjs/add/operator/map';
    @Injectable()
    export class ProjectsMainApi {
        apiUrl: string = "http://www.test.io/api/projects";
        headers: Headers = new Headers;
        project$: Observable<IProjectsMain[]>;
        private _ProjectsMainObserver: Observer<IProjectsMain[]>;
        private _dataStore: {
            project: IProjectsMain[]
        };
        constructor(private _http: Http) {
            this.headers.append('Content-Type', 'application/x-www-form-urlencoded');
            this.headers.append('X-Requested-With', 'XMLHttpRequest');
            //this.project$ = new Observable(observer => this._ProjectsMainObserver = observer).share();
            this.project$ = new Observable<IProjectsMain[]>(observer => this._ProjectsMainObserver = observer).share();
            this._dataStore = { project: [] };
        }
        public getProjectsMain() {
            this._http.get(this.apiUrl).map(response => response.json()).subscribe(data => {
                this._dataStore.project = data.project;
                this._ProjectsMainObserver.next(this._dataStore.project);
            }, error => console.log('Could not load projects.'),
                () => "doneskies");
        }
    }

花了一整天的时间在谷歌上搜索和处理代码，我不知道如何解决这个问题并使其编译，所以现在我希望有人知道如何用另一种方式来解决它，即我需要能够判断订阅何时发生并成功，但从我的组件内，最终结果应该会触发我的组件文件中的警报

将变量project的类型更改为服务中的Observable<any>或Observable<IProjectsMain[]>。

export class ProjectsListComponent implements OnInit {
    elementRef: ElementRef;
    project: Observable<any>;
...
}

它以前工作过，因为您可能将tsconfig.json更改为具有？：

"noEmitOnError": true
