Re: [install and use local::lib module]

Dear all,

How are you? I re-read the README file of the local::lib module. There was one more command missing:

echo 'eval "$(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)"' >>~/.bashrc

My new Perl settings in the .profile file are:

# Perl 5.38
export PATH=/usr/local/bin:$PATH
export PERL5LIB=$HOME/perl5/lib/perl5
eval `perl -I$HOME/perl5/lib/perl5 -Mlocal::lib`

Now everything works. But I still don’t understand the setup very well. What is the difference between the ‘.cpan’ and ‘perl5’ directories? What is their purpose? Thank you and have a great day ahead!

I would like to discipline myself and learn how to use the ‘local::lib’ module properly. I downloaded the source code of local::lib from cpan website and installed it with:
