CPAN hosts thousands of Perl modules that can be installed easily on your computer. The traditional method to install a module named foo::bar is by using the cpan command:
$ cpan foo::bar
However, the tool asks you to answer quite a few questions to go through with the module installation.
A highly recommended improvement to CPAN module installation is to use cpanminus.
The easiest way to install it is from your distribution package:
$ sudo apt install cpanminus
You can also install it directly from CPAN:
$ cpan App::cpanminus
After this, you can install any CPAN module by calling cpanm:
$ cpanm foo::bar
The advantage of using cpanminus is that it takes care of automating the module installation process as much as possible for you.
