How To Fix cpanm: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu cpanm is provided by cpanminus package.

cpanminus is:

cpanminus provides a command-line (non interactive) interface to automatically download, build and install Perl modules from CPAN.

It requires zero configuration, and stands alone. It also has a very low memory footprint compared to similar software: when running, it requires only 10MB of RAM.

It installs to wherever ExtUtils::MakeMaker and Module::Build are configured to. So if you’re using local::lib, then it installs to your local perl5 directory. Otherwise it installs to the siteperl directory.

cpanminus at a boot time checks whether you have configured local::lib, or have the permission to install modules to the sitelib directory. If neither, it automatically sets up local::lib compatible installation path in a perl5 directory under your home directory.

To fix this problem, we can install more using the command below.

sudo apt-get -y install cpanminus

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install cpanminus.

sudo apt -y install cpanminus

Or if you have aptitude installed you can use the following command.

sudo aptitude install cpanminus
