Angular2 - 应用程序/我-component.component.ts（1,25）：错误

2019-09-29 17:57发布

我学习angular2。已安装的node.js，NPM，打字稿。

我跑npm start

显示错误：

app/my-component.component.ts(1,25): error TS2307: Cannot find module 'angular2/core'.

我-component.component.ts

import {Component} from "angular2/core";

@Component({
    selector: 'my-component',
    template: `
        This is my component!
    `
})
export class MyComponentComponent {

}

的index.html

<html>
  <head>
    <title>Angular 2 QuickStart</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="styles.css">

    <!-- Polyfill(s) for older browsers -->
    <script src="node_modules/core-js/client/shim.min.js"></script>

    <script src="node_modules/zone.js/dist/zone.js"></script>
    <script src="node_modules/reflect-metadata/Reflect.js"></script>
    <script src="node_modules/systemjs/dist/system.src.js"></script>

    <script src="systemjs.config.js"></script>
    <script>
      System.import('app').catch(function(err){ console.error(err); });
    </script>
  </head>

  <body>
    <my-app>Loading...</my-app>
  </body>
</html>
