Angular 2 Karma测试（PhantomJS） - SyntaxError：使用保留字＆＃39; import＆＃39;

Question

由于jenkins的目的，我试图使用PhantomJS设置Angular 2 Karma测试。 虚拟测试工作正常，当我尝试从angular本身导入服务时出现问题。

问题

正在运行npm test

PhantomJS 2.1.1 (Mac OS X 0.0.0) ERROR
  SyntaxError: Use of reserved word 'import'
  at test/components/talks.spec.ts:1
PhantomJS 2.1.1 (Mac OS X 0.0.0): Executed 0 of 0 ERROR (0.114 secs / 0 secs)
npm ERR! Test failed.  See above for more details.

原因

档案talks.spec.ts

import {TalkService} from "../../app/services/talk.service"; <- Error here

    describe('Integration testing for talks', function() {
        let service : TalkService = new TalkService();

    it('should be able to run a method', function() {
        service.something();
    });
});

出于某种原因，我在使用PhantomJS时无法导入。我已经尝试了大量的解决方案，在我的项目充满依赖性试图寻找解决方案之后，我知道我无法解决这个问题。
