RMagick gem无法安装在Debian Stable上

Question

编辑：[修正] 问题是我已经安装了它，但不知道，并试图从源代码安装。这创建了两个版本，并且该宝石不知道要使用哪个版本。我通过去下载的源代码并运行来修复它

sudo make uninstall 

然后我再次运行了gem install rmagick，它工作正常！

[原来的问题]

我想在this railscast安装rmagick宝石等。这里是什么，我把我的Gemfile代码片段：

gem 'rmagick' 
gem 'carrierwave' 

当我运行捆绑安装，我得到以下的输出：

An error occurred while installing rmagick (2.13.1), and Bundler cannot continue. 
Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling. 

对此行：

我想我已经用尽了所有关于如何通过google/stackoverflow修复此错误的信息。我已经尝试安装开发包等。不知道该从哪里出发。任何帮助不胜感激。
