升级到 rc2 后，Angular2 快速入门应用程序不再工作

Question

我将基于教程/快速入门应用程序的 angular2 应用程序从 rc1 升级到 rc2。

npm install 报告一切正常：

npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

> typings install

以前，它工作得很好。现在，在加载第一页时，我收到了一堆 404 错误：

我做错了什么？

确保您拥有最新的 systemjs.config.js 文件。下面的块是在 RC2 发布后几天添加的-

  function packUmd(pkgName) {
    packages['@angular/'+pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
  }
