CPAN.pm (cpan
) is the original client. It comes with Perl, so you already have it. It has the most features. It has a lot of configuration options to customize the way it works, though virtually everyone accepts the default installation. It integrates easily with local::lib.
cpanminus (cpanm
) is an attempt to make a zero-configuration client that automatically does the right thing for most users. It's also designed to run well on systems with limited resources (e.g. a VPS). It doesn't come with Perl, but it's easy to install. It integrates easily with local::lib.
Its biggest limitation is its lack of configuration. If you want to do something unusual, it may not support it.
CPANPLUS (cpanp
) is an attempt to make a CPAN API that Perl programs can use, instead of an app that you use from the command line. The cpanp
shell is more of a proof-of-concept, and I don't know of any real advantages to using it.
In summary, I'd recommend either cpan
or cpanm
. If you have trouble configuring cpan
, try cpanm
. If your situation is unusual, try cpan
.
