【问题描述】：

我试图让 JSPM / Karma / Babel / Jasmine 一起工作。但是运行 karma start 时出现错误

15 04 2016 17:34:02.428:INFO [karma]: Karma v0.13.22 server started at http://localhost:9876/

    Error loading /Users/allen/dev/work/Web/wwwroot/src/app.js

我的文件夹结构：

> Web
  karma.conf.js
  -> node_modules
  -> test
    --> unit
  -> wwwroot
    --> src (all my js)
    --> jspm_packages
    config.js

我的 Karam.conf.js：

module.exports = function(config) 
  config.set(

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',

    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jspm', 'jasmine'],

    jspm: 
      // Edit this to your needs
      loadFiles: ['test/unit/setup.js', 'test/unit/**/*.js'],
      serveFiles: ['wwwroot/src/**/*.js'],
      paths: 
        '*': '*',
        'github:*': 'jspm_packages/github/*',
        'npm:*': 'jspm_packages/npm/*',
      ,
    ,

    // list of files / patterns to load in the browser
    files: [],
    proxies: 
      '/base/jspm_packages/': '/base/wwwroot/jspm_packages/',
    ,

    // list of files to exclude
    exclude: [],

    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: 
      'test/**/*.js': ['babel'],
      'src/**/*.js': ['babel'],
    ,

    babelPreprocessor: 
      options: 
        sourceMap: 'inline',
        presets: ['es2015-loose', 'stage-1'],
        plugins: [
          'syntax-flow',
          'transform-decorators-legacy',
          'transform-flow-strip-types',
        ],
      ,
    ,

    // test results reporter to use
    // possible values: 'dots', 'progress'
    // available reporters: https://npmjs.org/browse/keyword/karma-reporter
    reporters: ['progress'],

    // web server port
    port: 9876,

    // enable / disable colors in the output (reporters and logs)
    colors: true,

    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_INFO,

    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: true,

    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['Chrome'],

    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false,
  );
;

我的 app.js 有这些导入：

import  inject  from 'aurelia-dependency-injection';
import  Router  from 'aurelia-router';
import  Navscroll  from '../src/modules/scroll-anim.js'

我不确定我的代理设置是否正确或问题是什么？

【参考方案1】：

Error: Error: XHR error (404 Not Found) loading /Users/allen/dev/work/Web/aurelia-dependency-injection.js
Error loading /Users/allen/dev/work/Web/wwwroot/src/app.js

这是您的第一个问题。这不是您的代理的 XHRing。相反，它正在尝试使用路径 url。这肯定会失败，因为据我所知，XHR 只能执行 HTTP。您需要协议：//主机：端口/路径格式。

尝试转到http://localhost:9876/src/app.js 并查看浏览器中显示的内容。 （可能不需要包含 /src/ app.js 可能会从 root 提供。）

您一定是在某处错误地加载了app.js 文件。请包括您加载的地点app.js。
