RMagick gem无法在Debian Stable上安装

Question

编辑:[固定]问题是我已经安装它,但不知道,并试图从源安装.这创建了两个版本,gem不知道使用哪个版本.我通过转到下载的源并运行来修复它

sudo make uninstall

然后我再次运行gem install rmagick并且它工作了!

[原始问题]

我正试图在这个railscast中安装rmagick gem .这是我在gemfile中放置的片段:

 gem 'rmagick'
 gem 'carrierwave'

当我运行bundle install时,我得到以下输出:

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.

关于这条线:

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.我已经尝试过安装开发包等.不知道从哪里开始.任何帮助非常感谢.

"新的正确方法是安装libmagickwand-dev:

sudo apt-get install libmagickwand-dev然后你应该能够安装rmagick没问题."
