Ruby on rails Aptana Studio 3 Rails 2.x调试失败？

我正在使用Ruby 1.8.7在Windows XP上运行Aptana Studio 3，无法让集成调试器工作（从app explorer视图，运行命令->调试服务器）

我已经安装了rubyInstaller DevKit、ruby调试库和ruby调试ide gems。以下是我在尝试调用“调试服务器”时看到的错误

Fast Debugger (ruby-debug-ide 0.4.16, ruby-debug-base 0.10.4) listens on 127.0.0.1:4725
Fatal exception in DebugThread loop: The requested service provider could not be loaded or initialized. - socket(2)

我在Aptana支持论坛上就此展开了讨论

RadRails 2的rails调试器仍然可以正常工作，所以我切换到了它。

这是由Studio 3中的一个bug引起的：

这个错误应该在3.0.2版本中修复。另外，Christopher所附的链接也有关于这个问题的详细信息，包括在讨论结束时发布的用户解决方法
