在SystemJS上使用JSPM 404进行Karma / Jasmine单元测试设置

Question

我正在尝试使Karma / Babel / Jasmine / Aurelia一起工作，但是运行Karma Start时出现此错误

Chrome 50.0.2661 (Windows 10 0.0.0) ERROR
SystemJS was not found. Please make sure you have initialized jspm via installing a dependency with jspm, or by running 'jspm dl-loader'.

system.js文件位于lib文件夹中。

我的文件夹结构：

> Web
  karma.conf.js
  -> node_modules
  -> lib (systemjs is located here)
  -> js
     config.js
     --> ** (I will have more than one unit test folder but they will all be located at this level.  All my js will be located here as well.)
         --> Test
             --> Unit

我的karma.conf.js

业力在执行期间使用不同的基本路径，因此您必须添加到

System.config({
  baseURL: (typeof __karma__ !== "undefined") ? "base" : "/"
});

请记住，每次运行jspm install都会覆盖此基本路径，因此，如果要自动化环境，则可以定制解决方案以将该baseURL添加回原来的位置。
