我在运行 php selenium 测试时遇到问题。我刚切换到 Ubuntu 操作系统，现在我在 selenium 服务器上遇到了这个异常堆栈问题。

Chromdriver 正在运行

Starting ChromeDriver (v2.9.248304) on port 9515

这是我运行测试时的错误

There was 1 error:

为什么突然出现这个问题？如何解决？如果您需要任何其他信息，请告诉我，我会提供。提前谢谢你

您应该像这样设置 chrome 驱动程序选项:

java -jar selenium-server-standalone-2.53.0.jar -Dwebdriver.chrome.driver=chromedriver.exe

在 -Dwebdriver.chrome.driver= 之后，您应该输入 cromedriver 的路径。
