角度2:找不到名称"Subscription" [英] Angular 2: Cannot find name 'Subscription'

问题描述

尝试设置属性类型时，出现错误找不到名称'Subscription'.我应该从哪个包中导入它?

When trying to set the type of an attribute I get the error Cannot find name 'Subscription'. From which package do I import it from?

import { Component, OnDestroy, OnInit } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';

// I'm missing an import here. Just don't know which package to load from.

@Component({
  moduleId: module.id,
  selector: 'my-component',
  templateUrl: 'my.component.html',
  styleUrls: ['my.component.css']
})
export class MyComponent implements OnInit, OnDestroy {

  private sub: any;

  constructor(private route: ActivatedRoute,
    private router: Router) {}

  ngOnInit() {
    this.sub = this.route.params.subscribe(params => {
       let id = +params['id']; // (+) converts string 'id' to a number
     });
  }

  ngOnDestroy() {
    this.sub.unsubscribe();
  }

}

编辑:提供更详细的代码示例.

Provide a more detailed code example.

推荐答案

您必须像这样导入它:

import { Subscription } from 'rxjs';

原始答案

import { Subscription } from 'rxjs/Subscription';

在这里看看: https://angular.io/docs/ts/latest/guide/router.html 并且在该文档中有几个punker的链接.
