在本地安装ruby-debug19

我目前在 Windows XP 32位机器上运行 Ruby 1.9.2p0.自从我们升级到Ruby 1.9以来,我无法进行任何形式的调试.我被告知你需要新的ruby-debug19 gem才能让事情运行起来.问题是,我公司的代理阻止了gem依赖管理器连接外部存储库.没关系,我会自己下载gem并在本地安装.结果：

ERROR:  Error installing ruby-debug19-0.11.6.gem:

也许我做出了不合理的假设,因为我对Ruby很新,但看起来安装脚本试图连接外部存储库以获取某些内容.如果是这样,这是荒谬的,如果我能够自动地与经理这样做,为什么我会在本地安装gem？有没有人知道我可以以纯粹的本地离线方式安装调试器？我感谢任何帮助.
