Modern::Perl version 2011 required--this is only version 1.03 at my-perl-script.cgi

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

Greetings monks,
I've been reading chromatic "Modern Perl 2011-2012 edition" -- thank you chromatic! So in deciding to take the advice at the very beginning of the book, I added

use Modern::Perl 2011;
[download]

as stated, this translates to:

use 5.012;    # implies "use strict;"
use warnings;
[download]

Seems reasonable. I'm useing 5.12.5, and I always use warn.
But after adding that line, I receive the following error in a script that never complained before:

Modern::Perl version 2011 required--this is only version 1.03
[download]

Of course I'll reaquaint myself with the Modern::Perl docs. But just thought I'd mention it here, as it is quite unexpected.

Thank you for all your time, and consideration.

--Chris

#!/usr/bin/perl -Tw
use perl::always;
my $perl_version = "5.12.5";
print $perl_version;

It seems your version of Modern::Perl isn't modern enough, aka too old. It works for me with newest version from CPAN. Perl 6 - the future is here, just unevenly distributed	[reply]

Weird. He indicates in the book that everything works best with Perl 5.12.0 or newer. So I figured since my version of Modern::Perl (1.03) came with my version of Perl (5.12.5), everything would be "hunky-dory". --Chris #!/usr/bin/perl -Tw use perl::always; my $perl_version = (5.12.5); print $perl_version;	[reply]

I figured since my version of Modern::Perl (1.03) came with my version of Perl (5.12.5)... It's not a core module, so someone bundled it with your version of Perl. Unfortunately, the bundled version predates the year specifier. Upgrading to the most recent `Modern::Perl` version will let you use a year specifier (and it will be quick and easy).	[reply] [d/l]

Whomever built "(your) version of Perl (5.12.5)", might have included the older version. M::P does not come along with perl 5.16.3; it is also missing from 5.12.5 per module list. FWIW, current version is 1.20121103 on CPAN; also, no "2011" version is listed there.	[reply]

Best I can tell, there is no Modern::Perl version 2011. I think you've confused the date (or, rather ,part of the date) in the title you cite with a version number. Both CPAN and ppm list `Modern::Perl-1.20121103` (for perl 5.016); a naming convention which may clarify the problem.	[reply] [d/l]
