'；无法创建新会话；将selenium-server-standalone-3.9.1.jar与ChromeDriver和Chrome一起使用时出错

在过去的几天里，我使用SeleniumWebDriver运行测试，没有任何问题。但是，尽管我没有更改代码或系统中的任何内容，但在最近几次尝试创建新的浏览器会话时，我总是遇到以下错误：

无论我是通过代码创建会话，还是通过浏览器手动创建会话，都会发生这种情况

这是运行Selenium服务器和三个测试的结果：

我尝试过降级，重新安装所有东西，但似乎没有任何效果

我使用的是：

• Ubuntu 18.04
• Selenium Java Server 3.9.1
• 铬73
• 铬合金驱动器74

另外，奇怪的是，我的同事与我一起研究Selenium，现在在他们自己的系统上遇到了完全相同的问题。

此错误消息

…表示您的ChromeDriver版本为ChromeDriver=2.41

您的主要问题是所使用的二进制文件版本之间的不兼容，如下所示：

• 您使用的是chromedriver=2.41
• 的发行说明明确提到以下内容：

支持Chrome v67-69

• 您可能正在使用最新的GAed chrome=73.0
• 的发行说明明确提到以下内容：

支持Chrome v71-73

因此，ChromeDriver v2.41和Chrome浏览器v73.0之间存在明显的不匹配

---

解决方案

• 将ChromeDriver升级到当前级别
• 将Chrome版本保持在Chrome v71-73级别之间。（）
• 通过IDE清理项目工作区，并仅使用所需的依赖项重建项目
• 执行

  @测试

试试这个，希望它能帮助你！！感谢您的回复，它在帮助我们找到解决方案方面发挥了重要作用。唯一缺少的部分是我们还需要更新Selenium服务器版本。很抱歉迟了回答，再次感谢。干杯@zzzz4在您的问题标题中，您明确提到了Selenium Java Server 3.9.1，它应该按照我的解决方案工作。这就是答案。否则我会建议升级到最新的Selenium v3.141.59，作为一般建议。很高兴知道你的问题解决了。祝你好运
