我有一个 vue.js 应用程序，我使用以下指令安装了 Jest：

https://vue-test-utils.vuejs.org/guides/testing-single-file-components-with-jest.html。

当我运行npm test 时，出现错误。

? Test suite failed to run

TypeError: Cannot set property '_eventListeners' of undefined

  at Window.close (node_modules/jsdom/lib/jsdom/browser/Window.js:475:51)

我已经完成了文档中的所有内容，关于该应用程序的所有其他内容都很好，除了测试。请问，我该如何解决这个问题？

这是我的 package.json 配置文件：
