Question

我正在尝试为Angular应用程序执行单元测试，但是在Windows（7和10）下启动Karma测试时遇到问题。执行“ ng test”命令后，Karma开始编译，然后Chrome浏览器打开并尝试找到http://localhost:9876/?id=84122006。但是什么也没发生。然后在60000毫秒后发出一条消息“ Chrome在60000毫秒内没有捕获铬，正在杀死”，然后经过两次类似的尝试，它停止了。

我在互联网上发现了很多类似的问题，但是到目前为止似乎还没有找到特定的解决方案。

我尝试了以下操作：

使用Firefox而不是Chrome
在Chrome中使用了--no-sandbox标志
安装了最新的Karma 2.0.4
添加了环境变量NO_PROXY =“ localhost，0.0.0.0/4201，0.0.0.0/9876”
在两台不同的计算机上尝试过：一台使用Windows 7，另一台使用 Windows 10

以上任何措施均未导致任何结果。还是一样-浏览器启动，但是什么也没发生。

有人解决了这个问题吗？

提前感谢您的帮助！

我正在使用Node v8.9.3
