不知怎的，从今天起，我正在从我的黄瓜代码下面的错误 -硒的webdriver错误代码502
硒:: webdriver的::错误:: WebDriverError：意外的响应，代码= 502，内容类型=” text/html“ ，然后是整个页面的HTML文本。

这从今天早上开始突然发生，所以，我的问题是......错误代码= 502说什么？如果你看看这个日志的顶部 - 它说
Selenium::WebDriver::Error::WebDriverError: unexpected response, code=502
那么，这是什么意思？哪里有问题？这是代理问题还是其他问题？ 我试过不同的浏览器，并有相同的问题？
更新 -
这里是有趣的事情 - 当我改变了我的SDK从JRuby中1.5.6到Ruby 1.87，它工作正常...问题是只使用JRuby ...用Ruby SDK同样的事情工作正常...我尝试了各种版本的JRuby ..就像1.6.5和1.6.7，它抛出了相同的错误，但是当我尝试1.8.7它工作正常 - 它打开浏览器没有错误 -
这里是用Ruby 1.8.7
C:\Ruby187\bin\ruby.exe -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) C:/Ruby187/bin/irb --prompt simple
>> require "rubygems"

?> require "watir-webdriver"
