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'
|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.
This distribution does not 'use strict;' (or its equivalents) in all of its modules. Note that this is not about the actual strictness of the modules. It's bad if nobody can tell whether the modules are strictly written or not, without reading the source code of your favorite clever module that actually enforces strictness. In other words, it's bad if someone feels the need to add 'use strict' to your modules.
Add 'use strict' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.
|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).
There is more than one .pm file in the base dir, or the .pm files are not in lib/ directory.
Move your *.pm files in a directory named 'lib'. The directory structure should look like 'lib/Your/Module.pm' for a module named 'Your::Module'.
|meta yml has license||
This distribution does not have a license defined in META.yml.
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.
