How to Install Perl Modules on Ubuntu 24.04: A Step-By-Step Guide

Perl modules are reusable packages of Perl code that can be integrated into your existing Perl program to perform specific tasks. They may depend on other Perl modules to function properly, in which case both modules should be installed.

The Comprehensive Perl Archive Network (CPAN) is the largest repository for storing around 200,000+ Perl modules, most of which require the latest Perl version, so ensure Perl installed on your system is up-to-date.

To install Perl modules from CPAN, you need a command program, and there are three well-known and popular command-line programs: CPAN CLI, CPAN PLUS, and CPAN MINUS, that you can use for this purpose.

• CPAN CLI: It's been included in the Perl package (Since 1997) and guides you through a few questions upon first launch. After that, you can start installing modules by running the cpan -i Module::Name command.
• CPAN PLUS: It was an incomplete program that began with the intention of becoming a newer, better, and more featureful CPAN command program.
• CPAN MINUS: It's a simple tool that sidesteps the hassle of the default CPAN CLI, allowing you to easily install Perl modules using the cpanm Module::Name command.

The CPAN CLI is widely used and comes preinstalled with Perl. However, in this article, I'll show you how to install and use CPAN MINUS on Ubuntu 24.04, 23.04, and other versions.
