CPAN Minus review
A focused, open-source installer for CPAN modules, dependencies, mirrors, and local Perl libraries.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CPAN Minus, also called cpanm, is an open-source command-line package manager for obtaining, unpacking, building, and installing Perl modules from CPAN. It is aimed at developers and system administrators who need a focused way to install CPAN distributions, package dependencies, or modules from a local distribution. The package formats include Perl modules, CPAN distributions, and tar.gz archives. The published platform information lists Linux, with Perl 5.8.1 or later as a requirement.
Its strongest fit is the Perl and CPAN ecosystem. CPAN Minus can download distributions, unpack them, build Perl distributions, and install the resulting modules. It also automatically installs distribution dependencies, and it can install dependencies for a local distribution. Mirror support extends to configured CPAN mirrors and local mirrors, while offline installation supports workflows where packages must be obtained or installed without relying on a live network connection. These capabilities make it more than a simple download command, while keeping its scope centered on Perl package management.
Setup is deliberately lightweight: the project is designed to require no configuration and is distributed as a standalone executable. Installation can target system or user-controlled Perl library paths, including local Perl library locations, which gives teams flexibility when they do not want to modify a system-wide Perl installation. Choose CPAN Minus when your work centers on installing Perl modules from CPAN and you value dependency handling, mirror support, local-library installation, or standalone use. Choose another package manager when you need a broader multi-language ecosystem or a platform offering beyond the listed Linux environment.
