我正在尝试使用 ri 工具，但无法让它们工作。我也试过rvm docs generate了rvm docs generate-ri。两者都没有解决问题。我在 Mac OSx 版本 10.8.2 上。

谢谢

看起来您的 rdoc (4.0.1) 版本非常新。正如@theTinMan 所指出的，如果可能，您可能希望将 ruby​​ 版本提升到 1.9.x 或 2.0.0。

或者，您可以尝试删除 4.0.1 并安装 3.12.2，这是 ruby​​gems 上最新的 3.x 变体。

我深入研究了源代码以确定rdoc正在尝试Marshal.load缓存文件。也许您想清除缓存并重新运行rvm docs generate-ri以确保缓存编码准确。
