py+selenium运行时报错Can not connect to the Service IEDriverServer.exe

问题：

运行用例时，出现报错（host文件已加入127.0.0.1 localhost）：

raise WebDriverException("Can not connect to the Service %s" % self.path) selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service IEDriverServer.exe

而右下角event log也报错。

15:54 Cannot start internal HTTP server. Git integration, JavaScript debugger and LiveEdit may operate with errors. Please check your firewall settings and restart PyCharm

解决：控制面板-windows防火墙-允许程序通过防火墙

勾选IEdriverserver.exe→确定，即可解决！！
