I want to install Octopress in my computer.I try to do it like

Octopress 文档.

当我跑步时

bundle install

我收到错误信息

An error occured while installing RedCloth (4.2.9), and Bundler cannot continue.
Make sure that `gem install RedCloth -v '4.2.9'` succeeds before bundling.

所以，我跑

然后，我又收到一条错误消息:

then, I got a error message again:

ERROR:  Error installing RedCloth:
ERROR: Failed to build gem native extension.

    /usr/bin/ruby1.9.1 extconf.rb

推荐答案

您可能已升级到 Mountain Lion 并且尚未重建您的 ruby-1.9.2 安装尚未使用新的开发包.

You've probably upgraded to Mountain Lion and have not rebuilt your ruby-1.9.2 install yet with the new development packages.

rvm --force install 1.9.2
gem install bundle --no-ri --no-rdoc
bundle install

如果您没有正确安装 Mountain Lion 开发包，请使用 ThoughtBot 说明.

If you don't have the Mountain Lion dev packages installed correctly, use the ThoughtBot instructions.
