我正在尝试用Ruby构建一个web服务客户端。
当我尝试调用以下soap4r-ruby脚本来生成web服务客户端代码时：
wsdl2ruby.rb --wsdl *[web_service_url]* --type client
我得到以下错误：

当，我尝试调用以下代码来动态生成web服务客户端：
require 'soap/wsdlDriver'
WSDL_URL = "http://*[web_service_url]*"
factory = SOAP::WSDLDriverFactory.new(WSDL_URL)
driver = factory.create_rpc_driver
我得到以下错误：

为什么我会出现这些错误，以及如何解决这些错误？我知道web服务已经开始运行了，因为我可以在C#.Net中构建web服务客户端。
soap4r在Ruby 1.9中存在许多已知问题。您应该考虑使用一个较新的SOAP工具包，例如savon或handsoap。
