ruby-on-rails-3 - 将 redcarpet gem 添加到 Rails 应用程序后运行 "sh: make: command not found"时出现 "$ bundle"

Question

在将“gem 'redcarpet'”添加到 Gemfile 后运行“$ bundle”时，我得到以下信息:

$ bundle
...

Full gist here.

我正在使用带有不同 gemset 的 rvm。此应用程序使用@rails-3.0 gemset。关于该设置的 Here is my previous question。

我注意到“安装 redcarpet (1.17.2)...”行包括“/Users/robs/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/ 1.9.1 /rubygems/安装程序.rb”。这是问题的一部分吗？我怎样才能安装这个？

谢谢。

Time Machine更新后我遇到了同样的问题。安装 Xcode 和随之而来的开发人员工具解决了这个问题。
