[Solved]: How to check compatibility of perl modules with Perl version

Perl300 has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

I tried to check for this on CPAN as well but couldn't find it. I hope I am not missing to search somewhere specific on CPAN.

It's that before installing any new module I wanted to know if it would be compatible with the version on perl I have which is 5.10

Thanks in advance!

    If you use cpanm you can just run the tests like so:

    cpanm --test-only

    I also recommend using Perlbrew which will allow you to install and manage different versions of Perl, so you could still develop on a newer Perl and smoke test on 5.10.

      Thanks you Jeffa and Anonymous monk. Specially the CPAN Testers Matrix link went right into my bookmarks :-)

    CPAN won't install a module if it's not compatible with your perl version. If the module requires 5.10.1, it'll tell you and stop. What's more important to me is the minimum version of perl. For example, Perl::MinimumVersion requires a minimum of 5.006, so you can check it like this:
    #!/usr/bin/perl -l use strict; use warnings; use Perl::MinimumVersion; my $obj = Perl::MinimumVersion->new( "/usr/local/share/perl5/Perl/MinimumVersion.pm", ); print $obj->minimum_version;
    Unfortunately, it only works with files on your disk: files, scripts, code, modules, etc.
      Thank you thanos1983 and Khen1950fx. The minimum version is really important to know. Thanks for mentioning it here.
        That module comes with a frontend, perlver - The Perl Minimum Version Analyzer
