WebDriverException：通过Selenium v3.4.0和Geckodriver-v0.20.1启动Firefox浏览器45.0.1时拒绝连接

Question

我无法为以下脚本启动Firefox浏览器。

脚本#1:

System.setProperty("webdriver.gecko.driver", "D:\\selenium\\Geckodriver\\geckodriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);  
driver.close();

System.setProperty("webdriver.gecko.driver", "D:\\selenium\\Geckodriver\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.google.com");

我收到如下所述的错误消息：

我做错了什么？

Answer 1

从geckodriver版本中可以看到，geckodriver当前的最新版本是V0.20.1。您应该使用当前最新版本的Firefox浏览器。

此外，您使用的是selenium的旧版本（从这里开始，当前最新的版本是3.12.0)。

您需要更新firefox浏览器和selenium独立服务器。

如果你想（被迫）使用最旧的一个(45.0.1)，你应该使用相关的GeckoDriver。
