与远程浏览器通信时出错。它可能已经死了。Selenium Web驱动程序

我在Windows7中本地运行InternetExplorerDriver时遇到了相同的问题-（IEDriverServer_Win32_2.42.0.zip）

org.openqa.selenium.remote.UnreachablebrowserException: Error communicating with the remote browser. It may have died.

当我在TaskManager下检查正在运行的进程时，有多个IEDriverServer.exe正在运行的进程没有被正确清理。

运行以下命令，杀死所有正在运行的IEDriverServer.exe进程，并已解决此问题（对我而言）。

taskkill /F /IM IEDriverServer.exe解决方法

这是我的错误日志：
