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 后，我根本无法进行任何形式的调试。有人告诉我，您需要新的 ruby-debug19 gem 才能运行。问题是，我公司的代理阻止 gem 依赖管理器连接外部存储库。没关系，我自己下载 gem 本地安装。结果：
ERROR: Error installing ruby-debug19-0.11.6.gem:
ERROR: Failed to build gem native extension.

也许我做出了不合理的假设，因为我对 Ruby 还很陌生，但看起来安装脚本正在尝试连接外部存储库以获取某些东西。如果是这样，这很荒谬，如果我能够使用管理器自动安装gem，为什么还要在本地安装gem？有人知道我可以以纯本地离线方式安装调试器的方法吗？我很感激任何帮助。
