Kwalitee Issues


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 (14) does not match dist (16):
  • Missing in MANIFEST: MANIFEST, META.yml


Take a look at the META.json Spec at (for version 1.4) or (for version 2), and change your META.json accordingly.

If you are using Build.PL define the {requires}{perl} = VERSION field. If you are using MakeMaker (Makefile.PL) you should upgrade ExtUtils::MakeMaker to 6.48 and use MIN_PERL_VERSION parameter. Perl::MinimumVersion can help you determine which version of Perl your module needs.
