Question

我一直在尝试在CentOS 7上安装一些Perl模块，并遇到很多问题。我尝试使用yum，cpan和cpanm（每当尝试其他方法时从头开始），它们似乎按照安装日志正确构建，但是当我使用“ use Module_Name”运行脚本时，它会返回依赖项已过时的问题版本。其中一个模块是Date :: Locale。另一个是URI :: Encode。是否有正确的方法在CentOS 7上安装Perl模块，而无需进行调整或手动干预？

在Centos7上通过CPAN安装模块时，通常通过CPAN的自动配置将模块路径设置为use lib '/root/perl5/lib/perl5'。

查找通过CPAN（find / -name module_name）安装的模块之一，并查看其路径。如果它在默认目录之外，则可以在脚本中添加此路径。
