我正在尝试在 RHEL 上安装 snorby。 它要求使用 ruby​​，我试过了，现在我遇到了 rmagick 错误。

请帮忙。

      Could not create Makefile due to some reason, probably lack of
       necessary libraries and/or headers.  Check the mkmf.log file for more
        details.  You may need configuration options.

       Provided configuration options:
        --with-opt-dir
        --with-opt-include

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