我正在尝试在 Visual Studio 2015 应用程序中使用打字稿构建一个 Angular 2 应用程序。我正在使用角度候选版本 1。

运行应用程序时，我在浏览器的控制台中收到以下错误消息。

错误：错误：XHR 错误（404 未找到）正在加载 localhost:3622/node_modules/primeng/primeng(...)

我不明白为什么会收到此错误，因为我在 node_modules 下的应用程序文件夹中安装了primeng

请看下面文件夹结构的截图

我终于设法解决了这个问题。问题是我必须在 systemjs.js 文件中设置 'primeng': { defaultExtension: 'js' }
