我在我的 Windows 7 机器上安装了 JRuby 1.6.7.2（64 位）和 JDK 1.7.x（64 位）。现在，我只是尝试使用 Watir 启动浏览器（Firefox 13.0），但我不断收到一个似乎来自 JRuby + gems 内部的 HTTP 错误。我已经使用以下命令安装了 gem：

jgem install watir-webdriver
jgem install rspec
jgem install capybara
jgem install page-object
jgem install bundler
jgem install jruby-jars

这是我尝试使用 Watir 打开浏览器时遇到的堆栈跟踪错误：

C:\Windows\System32>jirb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'watir-webdriver'
=> true
irb(main):003:0> b = Watir::Browser.start("http://www.google.com", :firefox)

我已将 selenium webdrivers ie & chrome 添加到我的类路径中。当我使用 ie 或 chrome 执行此命令时，我收到类似的 HTTP 错误。这是我必须手动对 gem 文件进行的修复吗？

我对 Watir-webdriver gem 有同样的错误。问题是 http 代理设置，解决方案是在代码之前添加 no_proxy 环境。

ENV['no_proxy'] = "127.0.0.1"

我希望这可以帮助你！
