ruby - Ruby - watir：无法获得IEnum接口

我正在使用Windows XP，我需要使用带有ruby的watir，安装进行得很顺利，我的最后一次尝试是遵循这里的说明Failed WATIR installation Server 2003并且一切正常，除了这个“错误：生成文档时对于builder-2.1.2“然后安装完成没有更多的问题。

问题是，当我尝试运行示例脚本来执行谷歌搜索时，调用set函数时出现错误，到目前为止我还没有找到任何有用的信息，如果有人能帮我一把这将是伟大的:)）

顺便说一下，这里http://www.mail-archive.com/wtr-general@rubyforge.org/msg07722.html他们说它与WIN32OLE有关，但他们没有解释如何解决它（或者至少我没有得到它：s）

我安装的版本是


    ruby -v
    ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

    gem env

错误

c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/locator.rb:119:in `each': failed to get IEnum Interface (RuntimeError)

示例代码（Search.rb） 我删除了评论和其他不必要的行


    require "watir"

    test_site = "http://www.google.com"

    browser = Watir::Browser.new
    browser.goto test_site
    browser.text_field(:name, "q").set("pickaxe")  # here is the error when set is called
    browser.button(:name, "btnG").click
    browser.close
