How to install the perl DateTime module under CentOS8. yum install "perl(DateTime)" worked in CentOS7 but not in 8

Question

There are some Perl modules that could previously be installed with: yum install "perl(DateTime)" Under CentOS7. In CentOS8 I get the error:

No match for argument: perl(DateTime)

I have the same problem for perl(Template), perl(YAML::XS), perl(Crypt::Eksblowfish::Bcrypt) and perl(JSON::XS)

I tried searching with:

yum provides *DateTime*

But I can't find anything there either.

Whatever happened with perl-DateTime? On CentOS7 (and before) those were names for the packages for Perl modules -- does this not work anymore? – Caplin

@Caplin perl(Module::Name) is the syntax for what modules a perl package in RH distros provide. dnf/yum accept it directly and look up in provides when it doesn't match a package name. – Tamatamable

It's possible that these simply have not been packaged for RHEL/CentOS 8 yet. – Tamatamable

Looking at mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages it appears this is the case. – Tamatamable

Try install it with cpanm, i.e. sudo cpanm Date::Time. I tested this in a docker container for CentOS8 and it installed Date::Time to /usr/local/share/perl5 – Streamliner

@HåkonHægland Date::Time is a very different unrelated module. – Tamatamable

@Tamatamable Thanks, I missed that. – Streamliner

@Tamatamable sudo cpanm DateTime also works fine in my container. It just takes more time to install than Date::Time :) – Streamliner

perl-DateTime is no longer part of the CentOS 8 base OS. You'll need to enable the PowerTools repository, i.e. as root

# yum config-manager --set-enabled PowerTools
# yum update
# yum repolist
repo id                     repo name                                     status
...
PowerTools                  CentOS-8 - PowerTools                         ...
...

# yum install "perl(DateTime)"

or...

# yum install perl-DateTime

perl(YAML::XS) (AKA perl-YAML-LibYAML) should also be available.

perl(Template) (AKA perl-Template-Toolkit) and perl(Crypt::Eksblowfish::Bcrypt) (AKA perl-Crypt-Eksblowfish) no longer seem to be provided, not even in EPEL8. So you'll have to install them from CPAN.

Interestingly, I had to call it with repository name lowercase: yum config-manager --set-enabled powertools – Wallace

I can confirm that I had to call it with lowercase as well – Lanthorn
