我有以下代码来测试Selenium WebDriver。
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Starter
{
public static void main(String[] args)
{
WebDriver wd = new FirefoxDriver();
for(String arg: args) wd.get(arg);
wd.close();
}
}
它在我的工作站上运行，但不在服务器上运行。它给了我以下错误：

另外，如果重要的话，我在DISPLAY=:0设置的服务器上安装了xvfb。
请帮忙。
您使用的Selenium和Firefox浏览器的版本是什么？你正在使用geckodriver 0.19.0所以，如release notes中所述，你应该使用：
无论如何，如果你使用推荐的版本，你是否设置了geckodriver的路径？
你可以用不同的方式做到这一点：
System.setProperty("webdriver.gecko.driver", "yourPathTo/geckodriver");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.google.co.uk/");
/usr/local/bin/移动你的geckodriver最后，无论如何，请确保您的geckodriver是可执行的：
chmod +x geckodriver
这是几个星期前我偶然发现的一个问题。这是我如何解决问题。但首先：您的问题是不同堆栈持有者之间的兼容性问题。
解：
您需要使用以下工具组合
选项1：FF 52或53，GeckoDriver 0.16.0，Selenium Html Runner 3.4.0
选项2：FF 57或以上，GeckoDriver 0.19.0，Selenium Html Runner 3.10.0或3.11.0
注意：此修复程序适用于Ubuntu，Centos 7和Windows
以防万一：如果您正在测试Jenkins并遇到问题，请知道我可以帮助您。
