我有 Ruby 2.2，每次我遇到相同的错误时，我都无法从命令提示符运行任何文件 .rb：

C:/Ruby22/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- dl/import (LoadError)
        from C:/Ruby22/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
        from C:/Ruby22/lib/ruby/gems/2.2.0/gems/watir-classic-4.2.0/lib/watir-classic/win32.rb:1:in `<top (required)>'
        from C:/Ruby22/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
        from C:/Ruby22/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'

        from C:/Ruby22/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
        from C:/Ruby22/lib/ruby/gems/2.2.0/gems/watir-5.0.0-x86-mingw32/lib/watir/loader.rb:41:in `load_driver'
        from C:/Ruby22/lib/ruby/gems/2.2.0/gems/watir-5.0.0-x86-mingw32/lib/watir/loader.rb:33:in `load_driver_for'
        from C:/Ruby22/lib/ruby/gems/2.2.0/gems/watir-5.0.0-x86-mingw32/lib/watir/loader.rb:14:in `start'
        from test.rb:2:in `<main>'

我该怎么办？

Watir classic 不再处于积极开发中，您应该更新您的测试以使用 watir-webdriver gem
非常感谢！当我改为 watir-webdriver 时它起作用了
你能告诉我 Watir classic 和 Watir webdriver 的区别吗？
