嘗試運行Octopress捆綁包安裝時出現RedCloth makefile錯誤

Question

我剛剛從Git（github.com/imathis/octopress.git octopress）將Octopress提取到本地機器，但是當我嘗試運行捆綁安裝時說明，（http://octopress.org/docs/setup/）我得到一個錯誤。我正在運行Xcode 3.2版 - 我是否需要從Apple Developer網站升級到4.x？

我還運行每個RVM的Ruby 1.9.2p180。我是否需要運行更新的版本？

下面是輸出的，當我嘗試運行sudo的創業板安裝RedCloth：

Answer 1

你應該嘗試運行的Ruby 1.9.2-P290。

rvm install 1.9.2 && rvm use 1.9.2

Answer 2

這個固定的錯誤我..

sudo apt-get install ruby1.9.1-full 
sudo update-alternatives --config ruby 

（似乎錯誤時引起一些的ruby1.9.1-DEV建立文件/配置缺少）
