selenium - NightwatchJS /geckodriver/ selenoid：在 Firefox 上执行测试时，从 selenium 服务器检索新会话时出错，

Question

设置信息：OS - MacOS HighSierra - 10.13.3 DockerCE for Mac - 17.12.0-ce-mac49 Selenoid、Selenoid-ui - 最新的 Firefox - 58、geckodriver - 0.191 (0.190,0.170) Chrome - 63、ChromeDriver 2.34.522932 Selenium独立服务器 - 3.9.1

在本地设置上，使用相同的 geckodriver 使用 Firefox 和 Chrome 成功运行测试。

在远程设置中，我使用 Firefox 时测试失败，而使用 Chrome 则成功。

我用三种不同的 geckodriver 测试了这个场景，但结果是一样的。请帮忙。

错误堆栈跟踪清楚地提到Selenium Language Binding Art正在尝试连接IPv6 环回地址( )，根据讨论线程中的[::]:41809@JimEvans评论 Can't launch Selenium IE Driver升级到 3.9 版后

解决方案

一个可能的解决方案是禁用IPv6 环回地址并在远程设置上启用IPv4并执行您的Test。

看看这里： https ://github.com/nightwatchjs/nightwatch/issues/1628#issuecomment-357746215

这意味着您将不得不回退到 3.8 和 selenium Grid 设置。
