我正在尝试在OpsWorks上部署应用程序，但安装rmagick gem时出现问题。我有以下操作系统包：
libmagickwand-dev imagemagick libmagickcore-dev
以下是部署过程中出现错误的日志文件：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing rmagick (2.13.3), and Bundler cannot

Make sure that `gem install rmagick -v '2.13.3'` succeeds before bundling.
