CreatePlatformSocket（）返回错误：提供了无效的参数。 （0x2726）端口不可用。退出...与chromedriver和Selenium 3.2

Question

我无法使用selenium启动chrome（或任何其他浏览器）。 当我从家用电脑上运行时，相同的代码可以正常工作。所以我认为它与防火墙和安全设置有关。

selenium版本是3.2，Chrome驱动版本是2.28我也试过2.25（同样的错误）。使用的代码：

 System.setProperty("webdriver.chrome.driver", "K://browserdriver//chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://google.com");

错误讯息：

Answer 1

我找出了错误的原因;这是因为我的chromedriver.exe在网络驱动器上，而不是在机器上浏览器正在运行测试。解决方案是将chromedriver.exe移动到C盘下。
