红宝石 - watir：无法获得IEnum接口

Question

我使用的是Windows XP，我需要使用watir与红宝石，安装非常好，我最后一次尝试按照这里的说明Failed WATIR installation Server 2003，一切都很好，除了这个“错误：在为builder-2.1.2生成文档时“，安装完成时没有更多问题。

问题是当我尝试运行示例脚本来执行谷歌搜索我调用set函数时出现错误，到目前为止我还没有找到任何关于它的有用信息，如果有人可以给我一个一方面这将是巨大的:)

顺便说一句，这里http://www.mail-archive.com/wtr-general@rubyforge.org/msg07722.html他们说，这是关系到WIN32OLE但他们没有解释如何解决它（或至少我没有得到它：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)

的示例代码（Search.rb） 我删除注释和其他不必要的行

 

    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

Answer 1

Watir can't find IEnum interface线程您链接到说：

my best suggestion is to uninstall and reinstall Ruby, then re-install Watir on top of the new Ruby

，这将是我的建议了。
