ruby - watir : Failed to get IEnum Interface

Question

我使用的是 Windows XP，我需要将 watir 与 ruby​​ 一起使用，安装非常顺利，我最后一次尝试是按照此处的说明进行操作 Failed WATIR installation Server 2003一切正常，除了这个“错误:为 builder-2.1.2 生成文档时”，然后安装完成，没有更多问题。

问题是当我尝试运行一个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，如果有人可以帮助我那就太好了:)

顺便说一句，在这里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修复它(或者至少我没明白 :s )

我安装的版本是

    ruby -v    ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]    gem env    RubyGems Environment:      - RUBYGEMS VERSION: 1.3.7      - RUBY VERSION: 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]      - INSTALLATION DIRECTORY: c:/ruby/lib/ruby/gems/1.8      - RUBY EXECUTABLE: c:/ruby/bin/ruby.exe      - EXECUTABLE DIRECTORY: c:/ruby/bin      - RUBYGEMS PLATFORMS:        - ruby        - x86-mswin32-60      - GEM PATHS:         - c:/ruby/lib/ruby/gems/1.8         - C:/Documents and Settings/jamontoya/.gem/ruby/1.8      - GEM CONFIGURATION:         - :update_sources => true         - :verbose => true         - :benchmark => false         - :backtrace => false         - :bulk_threshold => 1000      - REMOTE SOURCES:         - http://rubygems.org/

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)    HRESULT error code:0x80004002      No such interface supported       from c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/locator.rb:119:in `locate'        from c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/container.rb:838:in `locate_input_element'        from c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/input_elements.rb:5:in `locate'        from c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/element.rb:54:in `assert_exists'        from c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/element.rb:315:in `enabled?'        from c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/element.rb:62:in `assert_enabled'        from c:/ruby/lib/ruby/gems/1.8/gems/watir-1.6.6/lib/watir/input_elements.rb:364:in `set'        from Search.rb:29

示例代码(Search.rb)我删除了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您链接到的线程说:

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

这也是我的建议。
