rake命令獲取「無法加載這樣的文件 - yaml /編碼」

Question

我想在CentOS 5.8上使用ruby-1.9.3-p194。我可以安裝它與rvm和系統（libyaml和libyaml-devel安裝）。但是我不能運行所有'耙'任務（不僅僅是'rake spec'）。

我得到了「無法加載這樣的文件 - yaml /編碼」。這是帶跟蹤的示例結果。 'rake'版本是'0.9.2.2'。我該如何解決它？

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

這不是一個耙子問題，這是一個紅寶石< => rails版本不兼容。您使用的是恐龍時代的rails版本中最​​新的穩定版本的ruby。

你需要做一些黑客來讓他們相互理解！

這裏是一個不錯的閱讀應該讓你開始：

這個要點也岩石：（！感謝喬納森）
