在Gemfile中添加“gem”redcarpet“后,运行”$bundle“时,我得到以下内容：
$bundle ...

我正在使用rvm与不同的宝石.此应用程序正在使用@ rails-3.0 gemset. Here is my previous question关于该设置.
我注意到“安装redcarpet(1.17.2)…”行包含“/Users/robs/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/installer”. RB”.这部分是问题吗？我该如何安装？
谢谢.
解决方法
Time Machine更新后我遇到了同样的问题.安装Xcode以及随之而来的开发人员工具修复了这个问题.
