ruby - soap4r - 未初始化的常量 REXML::Element

Question

我正在尝试在我的 Rails 项目(ruby 版本 1.9.3)中使用 soap4r 和 jira4r

在 Gemfile 中我有:

gem 'soap4r', :git => 'git://github.com/felipec/soap4r.git'
gem 'jira4r-jh'

当我尝试在我的模型中运行时

require "jira4r/jira-tool"

model Mymodel

  def mydef

    jira = Jira4R::JiraTool.new(2, "http://my.website.com/")
    jira.login("test@test.com","password")

  end
end

我得到一个错误:

uninitialized constant REXML::Element

rubyjedi-soap4r (1.5.8.01) lib/soap/rpc/driver.rb:151:in `call'

但如果我在独立的非 Rails ruby​​ 项目中运行相同的代码，它会正常工作。

我该如何解决？
