Problem installing modules with cpanm in Perl-CodePudding

I am absolutely new to Perl world. I've picked up a project left behind by a former employee & trying to get it to work. The project was originally in docker form & the requirement now is to run it in a non-docker form (don't get me started on this!) The project works like a charm in it's docker form. I've made the assumption that if I were to install all the packages installed in the docker file, the script should work. In the process of installing the packages, I am bumping into issues.

While the docker image uses ubuntu, the server I am trying on now uses RHEL7

I've installed build-essential libssl-dev tzdata bash curl wget perl cpanminus libcrypt-ssleay-perl libnet-ssleay-perl successfully.

Problem is with cpanm stuff from the docker file

[root@npcrver01 home]# cpanm Log::Log4perl
! Finding Log::Log4perl on cpanmetadb failed.
! cannot open file '/root/.cpanm/sources/http%www.cpan.org/02packages.details.txt.gz': No such file or directory opening compressed index
! Couldn't find module or a distribution Log::Log4perl ()

Please could someone help me here

gosh it's the proxy setting. I had to do

export https_proxy=http://<IP>:<port>
export http_proxy=http://<IP>:<port>
export HTTPS_PROXY=http://<IP>:<port>
export HTTP_PROXY=http://<IP>:<port>

Everything is working fine now
