Python 启动Huxley/Selenium录制会话时出错

我在尝试和赫胥黎开一张新唱片时遇到了问题。返回的异常错误如下所示：

我已将Huxley安装到python virtualenv中，并确保selenium服务器在尝试启动记录之前正在运行。我的赫胥黎文件是一个非常基本的文件：

[login]
url=http://2.2.2.2/login.html

我已经确认我的web应用程序可以使用上面的URL从Firefox访问，并且我可以成功导航到127.0.0.1:4444/wd/hub

如有任何建议，将不胜感激。如果我错过了任何重要的细节，让我知道，我会更新原来的帖子

Thx

更新：

对Fiddler的进一步调查显示POST请求包含sessionID的空值。由此产生的NullPointerException错误似乎是我的未知错误的根本原因

{"sessionId":null,"status":13,"value":    {"message":null,"localizedMessage":null,"suppressed":    [],"cause":null,"class":"java.lang.NullPointerException","hCode":3963113,"stackTrace":    [null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,    null,null,null,null,null,null]},"state":"unhandled     error","class":"org.openqa.selenium.remote.Response","hCode":2501105}

我仍在尝试解决该问题，我将再次更新我的结果。

该问题是由与Selenium 2.35和Firefox 30.0不兼容引起的-需要将Selenium更新到最新版本；但是，根据此问题，赫胥黎最初配置为仅使用2.35操作

更新requires.txt，如下所示：

selenium>=2.35.0
plac==0.9.1
Pillow==2.2.1
jsonpickle==0.4.0

允许huxley使用更新的Selenium版本运行
