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目录
  在/ usr / local / lib目录

• 运行ldconfig

这为我解决了这个问题。 （到下一个依赖…）

这个Linux系统究竟是什么？ 似乎缺少libMagickCore.so.4 。 如果我查看我的Ubuntu，我看它属于包libmagickcoreX", where the X`代表版本。我见过的最多Ubuntu是版本3，但我见过版本4的RPM，因此，在您的系统中，您可以安装该软件包版本。
