Issues to install Perl Modules on CentOS 7 - perl

Question

I’ve been trying to install some Perl modules on CentOS 7 and facing issues with a bunch of them. I tried with yum, cpan and cpanm (from scratch whenever I tried a different method), and they seem to be built correctly as per installation logs, but when I run my script with “use Module_Name;” it returns issues with dependencies having outdated versions. One of the modules is Date::Locale. Another one is URI::Encode. Is there a correct way to install Perl modules on CentOS 7, without tweaks or manual intervention?

When installing modules through CPAN on Centos7, the modules' path is usually set to use lib '/root/perl5/lib/perl5' by CPAN's autoconfigure.
Look for one of the modules you've installed via CPAN (find / -name module_name) and look at its path. If it's outside of the default dir, you can add this path in your script.
