我想在 CentOS 5.8 上使用 ruby​​-1.9.3-p194。我可以用 rvm 和系统安装它（安装了 libyaml 和 libyaml-devel）。但我不能运行所有的“rake”任务（不仅仅是“rake spec”）。

我得到“无法加载这样的文件——yaml/encoding”。这是一个带有跟踪的示例结果。“rake”版本是“0.9.2.2”。我该如何解决？

$ rake spec --trace
rake aborted!
cannot load such file -- yaml/encoding

这不是 rake 问题，而是 ruby​​ <=> rails 版本不兼容。您正在使用最新的稳定版 ruby​​ 和恐龙时代的 rails 版本。

你需要做一些黑客攻击才能让他们相互理解！

这是一本不错的读物，应该可以帮助您入门：
