This distribution doesn't create a directory and extracts its content into this directory. Instead, it creates more than one directories (some of which are probably system-specific hidden files/directories), or it spews its content into the current directory, making it really hard/annoying to remove the unpacked package.
Pack the distribution with a proper command such as "make dist" and "./Build dist", or use a distribution builder such as Dist::Zilla, Dist::Milla, Minilla.
|has meta yml||
The file "META.yml" is missing from this distribution. META.yml is needed by people maintaining module collections (like CPAN), for people writing installation tools, or just people who want to know some stuff about a distribution before downloading it.
Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
The distribution filename (eg. Foo-Bar-1.42.tar.gz) does not include a version number (or something that looks like a reasonable version number to CPAN::DistnameInfo)
Add a version number to the packed distribution. Or use a buildtool ('make dist' or 'Build dist')
|has proper version||
The version number isn't a number. It probably contains letter besides a leading 'v', which it shouldn't
Remove all letters from the version number. If you want to mark a release as a developer release, use the scheme 'Module-1.00_01'
|buildtool not executable||
The build tool (Build.PL/Makefile.PL) is executable. This is bad because you should specify which perl you want to use while installing.
Change the permissions of Build.PL/Makefile.PL to not-executable.
|manifest matches dist||
MANIFEST does not match the contents of this distribution.
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.
|prereq matches use||
This distribution uses a module or a dist that's not listed as a prerequisite.
List all used modules in META.yml requires
|package version matches dist version||
None of the package versions in this distribution matches the distribution version.
Fix the version(s).
|meta yml has license||
This distribution does not have a license defined in META.yml.
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 distribution is not required by another distribution by another author.
Convince / force / bribe another CPAN author to use this distribution.
These fails are not serious and don't affect your Kwalitee scores at all.
|has separate license file||
This distribution does not have a LICENSE or LICENCE file in its root directory.
