Error with perl 5.30 and Specio 0.47

[vinodarokiya]

Can't locate object method "_allow_classes" via package "Specio::Constraint::ObjectCan" at /opt/localperl/lib/site_perl/5.30.0/Specio/Constraint/Role/CanType.pm line 47.

May I plz know if we need to have any other dependency that needed to be installed?

Can you provide some code to reproduce this error? I can't do much with just an error message.

Hi Dave,

We have a package defined as Util :

package Util;

use strict;
use warnings;
use DateTime;

sub get_datetime {
my $dt = DateTime->now;
my $current_dt = $dt->datetime();
return $current_dt;
}

In one of the main script we use:
use Util qw(:all);

We are getting Compilation issue while trying to compile Util.pm itself:
Can't locate object method "_allow_classes" via package "Specio::Constraint::ObjectCan" at ~/perl5.30/Specio/Constraint/Role/CanType.pm line 47, line 755.

That's very odd. Can you try reinstalling Specio? I really don't know what could be causing this.

[vinodarokiya]

Yes i tried installing version 0.47 but still same issue,. I will check if something else is causing this issue even I wonder what s wrong :(

How are you installing modules? Are you using cpanm? Also, how did you install Perl?

This error suggests to me that there's something weird about your perl install or how you're installing modules.

[vinodarokiya]

We manually combine and install:
perl Makefile.PL
make test
make install
As we are unable to use cpanm to install in our Environment.

Doing it manually as you described should work fine.

Honestly, I'm really not sure what's going. I know that DateTime and Specio generally just work for people, and I don't think I've seen this error before.

Sure thanks for checking this out,let me check if I can figure out the issue
