Broken CPAN based install on Centos7: Fatal.pm missing #95

Closed daxbert closed 5 years ago

daxbert commented 5 years ago

Expectation: CPAN should be able to install Mouse w/ needed dependencies

Fails to install via CPAN on default centos7 docker image after installing make, gcc, perl and cpan

Error is "Can't locate Fatal.pm"

After installing Fatal via CPAN, Mouse is able to successfully install.

Found this possibly related reference for XML::SAX

Fatal.pm is not declared as a dependency because it is a standard library shipped in the core Perl distribution.

It would appear that some folks expect Fatal.pm to be part of the core perl distribution. This is not the case with Centos7. I'm going to experiment with installing perl, perl-core and perl-devel and see if this resolves the issue with Fatal.pm missing.

Maybe it should still be called out as a dependency?

Confirmed: 

# yum install perl-core

installs /usr/share/perl5/vendor_perl/Fatal.pm

Closing this issue as the solution is to have both perl and perl-core installed with Centos.
