Karma / PhantomJS无法运行用打字稿编写的单元测试

Question

我试图让我的单元测试使用Karma＆amp; amp;茉莉花。单元测试用Typescript和源文件编写。 测试在Chrome，Safari和＆amp ;;中运行 fine Firefox ，但在PhantomJS中失败。 错误：

PhantomJS 2.1.1 (Mac OS X 0.0.0) ERROR
  Error: (SystemJS) eval@[native code]

我试图连接phantomjs调试器，但它没有抛出任何错误，所以我有点卡在这里。

Karma配置：

module.exports = function (config) {
  config.set({
    customLaunchers: {
