我在尝试在 centos 上安装“rmagick”gem 时遇到问题。以下是我得到的输出。谁能帮我识别一下我缺少什么包裹？我已经安装了所有提到的另一个堆栈溢出线程：RMagick安装错误 https://stackoverflow.com/questions/7431707/rmagick-install-error

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
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib

--curdir
--ruby=/usr/local/bin/ruby
Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/rmagick-2.13.2 for inspection.
Results logged to /usr/local/lib/ruby/gems/1.9.1/gems/rmagick-2.13.2/ext/RMagick/gem_make.out
遵循建议后，现在我得到以下输出：
