Encountering unexpected issue with Angular2 Heroes application - traceur error code 404 popping up

I'm encountering the 404 traceur error while trying to launch my Angular2 app.

Many individuals have reported resolving it by removing multiline comments.

Others have mentioned updating their systemjs.config.js file.

I've attempted both solutions without success.

I created a Plunkr containing all of my TypeScript and configuration files.

This is how my systemjs.config.js looks:

(function (global) {
  System.config({
    paths: {
      'npm:': 'node_modules/'
    },
    map: {
      app: 'app',
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
      'rxjs':                       'npm:rxjs',
      'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
    },
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      },
      'angular2-in-memory-web-api': {
        main: './index.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);

Answer №1

If you're encountering an issue with your systemjs config file, consider incorporating the statement 'use strict'; at the beginning. I faced a similar situation in the past and adding this line helped resolve it.
