Updating/upgrading the perl module Sys::Hostname

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I want to run a piece of code that requires version 1.21 of Sys::Hostname.
My perl-5.28.1, installed using perlbrew at the time, came with version 1.20 of Sys::Hostname. I have searched online, but am unable to find how to install/upgrade to version 1.21. Can anyone help me out?

*edit: when I try to run:

cpanm Sys::Hostname

I get

skipping S/SH/SHAY/perl-5.28.1.tar.gz

That's quite strange, since Perl 5.28.1 should come with version 1.22 of Sys::Hostname, 1.20 would correspond with Perl 5.22.0 through 5.26.2. If you have multiple versions of Perl installed, are you sure you're running your script with the right one? For example, if your shebang is #!/usr/bin/perl, you might be running the script with your system Perl.

First of all, thank you for your comment! I must mention that I am relatively inexperienced with unix-based systems in general, so I apologise in advance for any stupidity on my part. After installing, I used perlbrew switch perl-5.28.1 . A run of perl -v confirms that perl 5.28.1 is the currently used version.

Ok, how do you run the Perl script? Is it ./script.pl, or perl script.pl? Or are you maybe using cron to run the script? Also, what does the first line of the script look like (the "shebang" line), is it #!/usr/bin/perl, or maybe #!/usr/bin/env perl?

I run with ./script.pl. The shebang line is #!/usr/bin/env perl. Sorry it took me a while to respond, I was away from the pc that has the files on it.

Ok, when you run ./script.pl, it'll use the perl in the shebang line, since that's /usr/bin/env perl, env should use whichever perl comes first in the PATH - in other words, it should be the same perl as when you type just perl on the command line. On the same command line as you run ./script.pl, what does perl -MSys::Hostname -le 'print "$] $Sys::Hostname::VERSION"' output? It should output 5.028001 1.22. If not, please edit your question and add the full output of perl -V (that's a captial letter -V, not lowercase).
