Why do I get many Moose warnings when I start Catalyst? - perl

Question

I am having an issue (Catalyst related) apparently with Moose/Class::MOP. Starting my server I get the following output... (shown below in all its glory)

I am new at Catalyst (and I do like it, I just want to successfully get it up and running). I have checked the latest versions of Moose and Class::MOP and they are up to date (as far as CPAN is concerned).
Hopefully someone familiar with Moose has seen this before. Any suggestions or a place to start checking would be appreciated.

Answer 1

You're running an old version of Catalyst. This issue has been fixed in commit r13516 and is already available on CPAN as of version 5.80026 (5.80028 is latest and recommended).
Catalyst was using some deprecated feature of Moose, which just recently started warning.

Answer 2

So, you're right, the current Cat stuff has a fairly broken dependency chain. You can see from the current pass/fail on the CPAN for 5.80030 that fails are much higher than normal.
There are several bumps depending on the state of your current modules/versions. This worked for me this morning (I'm not sure if it's overkill)-
cpanm -v namespace::clean
cpanm -v namespace::autoclean
cpanm -v B::Hooks::EndOfScope
cpanm -v Package::Stash
cpanm -v Class::MOP Moose MooseX::Types
cpanm -v MooseX::Role::WithOverloading::Meta::Role::Application
cpanm -v Catalyst Catalyst::Devel
And if you're using Config::General for your configuration, this is a good idea too:
cpanm -v Config::General
If you get those in and it won't start, just read the stack trace (backwards) looking for names or missing functions/methods. Anything you see as a problem, upgrade. It's a "stable" kit but it's a collection of moving targets and everything has to line up.
