注意：它连续24天连续工作了两天，今天我经常遇到这个错误。

note: It worked two days continuously 24/7 and today I am getting this error frequently.

推荐答案

问题

我在Windows 7本地运行InternetExplorerDriver有同样的问题 - （IEDriverServer_Win32_2.42.0.zip）

I had the same problem running InternetExplorerDriver locally in Windows 7 - (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

When I checked the running processes under TaskManager, there were multiple IEDriverServer.exe processes running, that hadn't been cleaned up properly.

解决方案

运行以下命令，终止所有正在运行的 IEDriverServer.exe 进程，并解决了这个问题（对我而言）。

Running the following command, killed all running IEDriverServer.exe processes, and resolved this issue (for me).

taskkill /F /IM IEDriverServer.exe
