此时，在所有其他途径都失败之后，我已经在绝望中尝试过很多很多事情。
到目前为止：
我对上面的内容进行了全面安装，但它们似乎没有影响随机EOFError。我有80％的时间得到错误，有20％的时间得到错误。我旁边的另一位开发人员拥有相同的OSX Yosemite版本，相同的设置，并且从未遇到过EOFError（因此我尝试了上述激烈的步骤来治愈环境）。

如果我使用:selenium（firefox / chrome）或:webkit（或:webkit_debug）
鉴于相同的代码库适用于其他开发人员的机器（相同的OSX版本，相同的ruby版本，相同的购买日期，相同的升级路径），我不确定环境中的哪些因素影响了结果。堆栈的起始行是visit '/'，它是visit的第一个scenario。即使visit示例中的后续Scenario Outline次尝试也会开始工作（通常在第3个示例中）。
在:webkit下运行时，我会在控制台中看到这些：

注意：我试图清理插件目录，然后他们不断回来。我确实想要解决这个烦恼，但在这一点上，它只是那个而不是一个表演的终结者。
在使用Google Chrome He驱动程序时，我很惊讶地看到控制台中对:webkit的引用，因为它应该通过QT安装brew 5.4.0。即使Chrome没有运行，这些也发生了。
成功运行后，我在控制台中看到：

欢迎提出任何建议，与EOFError避难所相关的所有其他途径对我来说都是无关紧要的。

我对谷歌浏览器的相互作用感到困惑，当我希望:webkit驱动程序使用brew安装的qt时，我很困惑。我错过了什么？
ChromeDriver吗
大约在2014年1月1日使用ChromeDriver (v2.9.248307)，似乎只要我从路径中拉出来，一切都会好起来的。请注意，由于这个问题有点随机，我无法确定结果。我正在更新到ChromeDriver 2.13.307650以查看它是否更好。请再次注意我没有使用selenium / chrome，而是使用webkit驱动程序，因此我仍然不知道为什么这会影响测试。即便如此，我还不确定chrome与问题有什么关系（尽管到目前为止测试会暗示其他情况）。
/ Library / Internet Plug-Ins !!!!!
这必须是缺失的环节。 :webkit没有任何理由可以与谷歌浏览器进行任何相互作用，但仍会看到与谷歌浏览器相关的偶尔的EOFError和OSX控制台消息。部分原因是，即使我删除了冒犯QT的文件，例如/Library/Internet Plug-Ins/o1dbrowserplugin.plugin/Contents/MacOS/o1dbrowserplugin，但当您重新启动Chrome时，会继续。我在chrome://plugins禁用了它们并不重要。所以，我真的需要一种让QT忽略它们或所有插件的方法。 Related QT issue here
当前解决方法
删除有问题的插件
sudo rm '/Library/Internet Plug-Ins/o1dbrowserplugin.plugin/Contents/MacOS/o1dbrowserplugin'
sudo rm '/Library/Internet Plug-Ins/googletalkbrowserplugin.plugin/Contents/MacOS/googletalkbrowserplugin'
运行测试。
如果您重新启动CHROME ，插件将再次出现。冲洗并重复。
显然，如果你不重新启动Chrome，他们仍然可以回来，只需看你的日志并冲洗并重复。
对此related QT issue的解析将允许我们忽略插件。
