尝试运行Octopress捆绑包安装时出现RedCloth makefile错误

Question

我刚刚从Git（github.com/imathis/octopress.git octopress）将Octopress提取到本地机器，但是当我尝试运行捆绑安装时说明，（http://octopress.org/docs/setup/）我得到一个错误。我正在运行Xcode 3.2版 - 我是否需要从Apple Developer网站升级到4.x？

我还运行每个RVM的Ruby 1.9.2p180。我是否需要运行更新的版本？

下面是输出的，当我尝试运行sudo的创业板安装RedCloth：

Answer 1

你应该尝试运行的Ruby 1.9.2-P290。

rvm install 1.9.2 && rvm use 1.9.2

Answer 2

这个固定的错误我..

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

（似乎错误时引起一些的ruby1.9.1-DEV建立文件/配置缺少）
