Selenium remoteWebDriver (& SauceLabs) Firefox moseMoveTo 动作异常

Question

同时使用 SauceLabs 中任何可用的 OS（除了 Linux，最新可用的 Firefox 版本太旧），通过执行以下 ActionChain：

hover = ActionChains(driver)
hover.move_to_element(elm_Men_Menu).perform()

它抛出以下错误：

追溯：

本地运行完美。我正在使用 geckodriver 0.17.0 和 Selenium 3.4.3（已编辑）。这是先前报告的 Selenium 错误，但已针对 Selenium 3.x 和 geckodriver 0.15.0 (https://github.com/SeleniumHQ/selenium/issues/2285). For the SauceLabs test I am using Selenium 3.4.0 (as can be seen in the error report) and in SauceLabs documentation, for Firefox 53 and higher versions, geckodriver 0.16.0 is used (https://wiki.saucelabs.com/display/DOCS/Test+Configuration+Options#TestConfigurationOptions-SeleniumVersion) 解决，原则上应该支持 move_to_element() 操作。

我做错了什么吗？有没有办法指定 geckodriver 版本？到目前为止，所需的功能如下所示：

desired_cap = {
  'platform':"Mac OS X 10.12",
  'browserName':"firefox",
  'version':"54",
  'seleniumVersion':"3.4.0",
}

编辑 1：我没有提到它，但它适用于 Chrome 和 IE11

编辑2：在Linux中使用selenium独立服务器（3.4.0）在本地执行代码时出现同样的问题。 geckodriver 版本为 0.17.0。完全相同的回溯，除了 System info: host:

Answer 1

已解决：

Selenium 已经意识到这个问题：

https://github.com/SeleniumHQ/selenium/issues/4008

已经解决，将在3.5版本中可用：

现在可以解决克隆主存储库，自己构建 selenium 服务器并使用 -enablePassThrough 标志启动节点
