以下是我的应用程序正在使用的版本： -

rmagick（2.12.2）
imagemagick 6.2.8.0-4.el5-5.3
操作系统： - Centos 5
提前致谢....
我在RHEL5上解决了这个问题，并进行了以下更改：
添加以下几行：
/ usr / lib目录
在/ usr / local / lib目录
运行ldconfig
这解决了我的问题。 （关于下一个依赖关系..）
什么是Linux系统？ 它似乎缺少libMagickCore.so.4 。 如果我看看我的Ubuntu，我发现它属于libmagickcoreX", where the软件包libmagickcoreX", where the X代表版本。我见过的最多的Ubuntu是3版本，但是我已经看到了版本4的RPM，所以在你的系统中你可以安装这个软件包版本。
