Gem [resolved] 尝试用 Jira4r 这个 gem 通过 soap 操作 Jira，但 require 失败

所需的两个 gem（soap4r 和 jira4r）都成功 install 了，但是在 irb 中按照教程 require 就抱错，cannot load such file，gem 不是装上了吗？

我将 require 'jira4r/jira4r'，换作了 'jira4r'，结果得到了更多的抱错...

终于找到解决方案了，记录在这里吧，日后说不定有人会用的上：
1、require 'jira4r' 而非 require 'jira4r/jira4r' 2、(irb 中) require 'jira4r' 后会出现‘XML processor module not found’的抱错提示，其解决办法是 (windows 下面)
- 打开 C:\Ruby193\lib\ruby\gems\1.9.1\gems\soap4r-1.5.8\lib\xsd\xmlparser.rb
- 将其中 66 行的 c.to_s.downcase == name 改为 c.to_s.downcase == name

收工，终于可以在 Ruby 里面 talk to Jira, hi5
