gem 安装ruby插件的时候 出现了一个错误
Installing rmagick 2.13.4 with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
...
Can't install RMagick 2.13.4. You must have ImageMagick 6.4.9 or later.
查看现在系统的设置(系统环境位cento5.1)
# rpm -aq|grep -i imagemagick
ImageMagick-6.2.8.0-15.el5_8
ImageMagick-devel-6.2.8.0-15.el5_8
ImageMagick-6.2.8.0-15.el5_8
ImageMagick-devel-6.2.8.0-15.el5_8
原来是Imagemagick的版本过造成的。
解决参考

原来的全卸载了,否则会有冲突
yum remove ImageMagick*
rpm -Uvh http://rbel.frameos.org/rbel5
yum install ImageMagick-devel ImageMagick-c++-devel --disablerepo="base"
gem install rmagick
