文件 RMagick2.so 存在于给定路径 /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/rmagick-2.12.2/lib 中。

提前谢谢....

Answer 1

我通过以下更改在 RHEL5 上解决了这个问题：

• 创建/etc/ld.so.conf.d/local.conf

• 添加以下行：

  /usr/lib
  /usr/local/lib

• 运行ldconfig

这为我解决了这个问题。 （继续下一个依赖..）

这到底是什么Linux系统？似乎缺少libMagickCore.so.4。如果我查看我的 Ubuntu，我发现它属于包 libmagickcoreX", where theX` 代表版本。我在上一个 Ubuntu 中看到的最多的是第 3 版，但我见过第 4 版的 RPM，因此在您的系统中您可能能够安装该软件包版本。
