打字稿-茉莉花-业力

Question

我有一个简单的打字稿项目，想做单元测试。 我配置了茉莉花，并且运行正常。 现在我想安装业力并对其进行配置。

测试文件位于spec文件夹下，程序代码位于src文件夹下。 我们有一个简单的单元测试文件（* .spec.ts），带有如下的import语句：

import { IEvento } from '../src/IEvento';
import * as ie     from '../src/InitEvento';

当运行Jasmine时，所有工作都没有问题，但是当我启动业力时，会出现此错误：

An error was thrown in afterAll
  Uncaught ReferenceError: exports is not defined
  ReferenceError: exports is not defined
      at src/IEvento.js:2:23

karma.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

      },
      transformPath: function(path){
          return path.replace('/\.ts$','.js');
      }
    },

    autoWatch: true,
    // start these browsers

  })
}

你能帮我吗？
