Under maintenance.

Most probably CPANTS databases are being regenerated from scratch due to major changes in Kwalitee metrics or updates of relevant modules/perl. Usually this maintenance takes about a day or two, and some of the information may be old or missing tentatively. Sorry for the inconvenience.

Kwalitee Issues


Change the permissions of Build.PL/Makefile.PL to not-executable.


Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.


  • MANIFEST (59) does not match dist (61):
  • Missing in MANIFEST: META.json, META.yml


Take a look at the META.json Spec at http://module-build.sourceforge.net/META-spec-v1.4.html (for version 1.4) or http://search.cpan.org/perldoc?CPAN::Meta::Spec (for version 2), and change your META.json accordingly.


Upgrade your META.json generator so it produces valid JSON.

Error: '"' expected, at character offset 1 (before "{{}\r\n{ "abstract...")


Upgrade your YAML generator so it produces valid YAML.

Error: CPAN::Meta::YAML failed to classify line '{---}'


Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.


This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
