我正在用这个制作应用程序webpage https://hackernoon.com/a-guide-to-tdd-a-react-redux-todolist-app-part-1-b8a200bb7091
我尝试测试 e2e-tests，但没有成功。
该程序无法启动 selenium 服务器。我该如何解决？
npm-v：5.6.0
纱线-v：1.5.1
操作系统-v：10.12.6
此外，我已经完成了 selenium 服务器是否可以工作的测试。结果，selenium 服务器也无法工作。
I tried this way https://gist.github.com/stoshiya/3dc36187ede3e6eee3e4测试硒服务器
e2e-测试错误如下
