我正在尝试安装机车CMS，但我在安装时收到有关rmagick的错误：
An error occurred while installing rmagick (2.12.2), and Bundler cannot
continue.
Make sure that `gem install rmagick -v '2.12.2'` succeeds before bundling.
我检查了日志，这是rmagick显示的错误：
$ gem install rmagick -v '2.12.2'

我在搜索引擎优化和谷歌上发现了类似的问题，但我现在已经尝试了大约3个小时的各种修复，但仍然无法使其发挥作用。请指教，谢谢！
