从这里我管理我的元素..
注意：它 24/7 连续工作了两天，今天我经常收到此错误。
【问题讨论】：
-
我们所拥有的只是这里的堆栈跟踪。请提供更多信息以增加您获得答案的机会。什么代码（一小部分）重现了这个问题？系统在工作和失败之间发生了哪些变化？您是否尝试过在新系统上运行它？它在那里失败了吗？
-
另外，鉴于您收到了权限被拒绝错误，您是否检查过您的防火墙是否阻止了 selenium？
-
我在同一个系统上工作，我不认为我的防火墙阻止了 selenium。你想让我展示我写的代码@Vish
-
请仔细检查您的防火墙确实不是问题所在。随机故障通常指向这种东西。是的，需要代码 - 但不要过度，只需粘贴所需的代码。
-
该异常本身可能是任何事情：从驱动程序兼容性问题到网络问题。所以堆栈跟踪在这种情况下没有帮助。如果您使用 RemoteWebDriver 从机器 A 到机器 B 远程运行测试，请尝试在机器 B 上本地运行它们。如果您没有远程运行测试，请尝试查看如果您使用 WebDriver 而不是远程驱动程序（不是硬开关）。将帮助您消除网络问题和驱动程序问题
