Perl is a versatile programming language that’s been around for decades, and one of its significant strengths is its vast repository of libraries available on CPAN (Comprehensive Perl Archive Network). Installing CPAN modules is essential for extending Perl’s capabilities, and this guide will show you how to do it efficiently in 2025.

Prerequisites

Before you start installing CPAN modules, ensure you have:

1. Perl Installed: You can download it from the official Perl website.
2. CPAN Client: Most modern Perl installations come with a CPAN client out of the box.

Step-by-Step Guide to Installing CPAN Modules

1. Update CPAN Client

First, you need to ensure that your CPAN client is up-to-date. Open your terminal and enter the following command:

1

cpan

Once the CPAN shell is open, update your CPAN client:

1
2

cpan> install CPAN
cpan> reload cpan

2. Install CPAN Modules

After updating the CPAN client, you can proceed to install modules. For example, to install a module named Module::Name, use:

1

cpan> install Module::Name

3. Using cpanm for Easier Installation

In 2025, cpanm, part of the App::cpanminus distribution, remains one of the easiest ways to install modules:

1. Install cpanm:

1

   cpan App::cpanminus

1. Use cpanm to Install Modules:

1

   cpanm Module::Name

cpanm simplifies the installation process, automatically handles dependencies, and is less verbose than the default CPAN client.

4. Verify Installation

After installing your desired module, verify its installation by running:

1

perl -MModule::Name -e 1

If there are no errors, the module is installed correctly.

Best Practices

• Keep Perl Updated: Always ensure you have the latest version of Perl for compatibility.
• Regularly Update Installed Modules: Use cpan-outdated with cpanm:

1
2

  cpanm --self-upgrade
  cpan-outdated | cpanm

• Use Local::Lib for Personal Installations: If you don’t have root access, consider using local::lib to maintain your modules:

1

  cpanm --local-lib=~/perl5 Module::Name
