cpan (this article) or cpanm can be used to install a Perl module.

• Install a module using cpanm
• Install a module using cpan (this article)

Before installing a module, you may want to use the perldoc command to determine if the module is installed.

perldoc -l Net::SSH:Perl

Or this command.

perl -MNet::SSH::Perl -e 'print $INC{"Net/SSH/Perl.pm"}'

On a Red Hat Distribution (CentOS, Fedora, Red Hat), the dnf install or yum install command can be used to install cpan.

dnf install perl-CPAN

Start the cpan interactive prompt.

cpan

Then, use the install module_name (or force install) command to install a module. In this example, the SSH module is installed.

cpan> install Net::SSH::Perl

If the install fails, you can try with the force option.

cpan> force install Net::SSH::Perl
