紅寶石 - watir：無法獲得IEnum接口

Question

我使用的是Windows XP，我需要使用watir與紅寶石，安裝非常好，我最後一次嘗試按照這裏的說明Failed WATIR installation Server 2003，一切都很好，除了這個「錯誤：在爲builder-2.1.2生成文檔時「，安裝完成時沒有更多問題。

問題是當我嘗試運行示例腳本來執行谷歌搜索我調用set函數時出現錯誤，到目前爲止我還沒有找到任何關於它的有用信息，如果有人可以給我一個一方面這將是巨大的:)

順便說一句，這裏http://www.mail-archive.com/wtr-general@rubyforge.org/msg07722.html他們說，這是關係到WIN32OLE但他們沒有解釋如何解決它（或至少我沒有得到它：S）

我安裝的版本是

 

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

錯誤

的示例代碼（Search.rb） 我刪除註釋和其他不必要的行

 

    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線程您鏈接到說：

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

，這將是我的建議了。
