Question

我遇到了Angular 2 + Typescript的问题，每当我尝试吞下构建它会向我显示相同的错误时，我已经尝试了所有内容，包括放置＆lt; reference＆gt;文件中的标签。怎么办？

import {Observable} from "rxjs/Rx";

import {Injectable,EventEmitter,Output} from "angular2/core";

@Injectable()
export class ROOT_SCOPE {
  data: any;
  dataChange: Observable<any>;
  @Output dataChangeObserver: EventEmitter=new EventEmitter();

  constructor() {
    this.dataChange = new Observable((observer:Observer) => {
      this.dataChangeObserver = observer;
    });
  }

  set(data:any) {
    this.data = data;
    this.dataChangeObserver.next(this.data);
  }
}

Answer 1

由于System.config.js配置错误，我之前遇到了同样的问题。尝试检查配置是否正确。

Answer 2

配置外部网络工具

将Visual Studio配置为使用全局外部Web工具而不是Visual Studio附带的工具：

•使用“工具”打开“选项”对话框选项

•在左侧的树中，选择“项目和解决方案”|外部Web工具。

•在右侧，将$（PATH）条目移到$（DevEnvDir）条目上方。这告诉Visual Studio在使用自己的外部工具版本之前使用全局路径中的外部工具（例如npm）。

•单击“确定”关闭对话框。

•重新启动Visual Studio以使此更改生效。
