Question

我一直在关注一个教程并且在与ngModel进行双向数据绑定时遇到了问题。经过研究，我发现了Plunkr并决定制作一个，看看它是否只是我的电脑。当然，一切都按照预期的方式运行，所以现在我不知道要弄清楚出了什么问题。一切正常，直到它在代码中使用[（ngModel）]的部分，我开始得到这个错误

zone.js：388未处理的承诺拒绝：模板解析错误：无法绑定到'ngModel'，因为它不是'input'的已知属性。

触发它的代码实例位于app.component的模板中，即

<input [(ngModel)]="hero.name" placeholder="name">

我正在使用Windows Vista 32位，NodeJS 5.0.7和npm 3.6.0。

我的package.json文件看起来像这样

    {

  "version": "1.0.0",
  "scripts": {
    "start": "tsc && concurrently \"tsc -w\" \"lite-server\" ",
    "lite": "lite-server",
    "tsc": "tsc",
     "tsc:w": "tsc -w"
  },

    "typescript": "^2.0.3"
  }
}

是否有人看到可能导致此问题的不同软件包版本的内容？

Angular 2：[（ngModel）]在我的电脑上生成错误，但同样的代码适用于Plunkr
