我收到此错误 Error message in console

这是我的文件： systemjs.config.js 

/**
 * System configuration for Angular samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      'app': 'app',

我需要帮助人员，我确实做了很多尝试，但仍然找不到任何解决方案，并且无法启动我的应用程序。我不知道确切的问题是什么，但取决于此错误的原因可能与脚本或软件包有关。我不知道我会对此表示赞赏
