我正在尝试使用 serenityJS + Jasmine 在 Angular Web 应用程序上运行组件测试，但遇到了以下错误。知道如何解决这个问题吗？

信息：

错误：fakeAsync() 测试助手需要 zone-testing.js，但无法找到。请确保您的环境包含 zone.js/dist/zone-testing.js 堆栈：

   Error: zone-testing.js is needed for the fakeAsync() test helper but could not be found.
           Please make sure that your environment includes zone.js/dist/zone-testing.js
