Cpanm with local library installation

One of the issue I kept facing when developing local Perl modules installation and dependency management.

$ cpanm -nq --installdeps --with-develop --with-recommends .
! Can't write to /usr/local/share/perl/5.26.0 and /usr/local/bin: Installing modules
! to /home/foobar/perl5
! To turn off this warning, you have to do one of the following:
!  - run me as a root or with --sudo option (to install to 
!    /usr/local/share/perl/5.26.0 and /usr/local/bin)
!  - Configure local::lib in your existing shell to set PERL_MM_OPT etc.
!  - Install local::lib by running the following commands
!    cpanm --local-lib=~/perl5 local::lib && eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)

Either we do this manually everytime.
$ cpanm --local-lib=~/perl5 local::lib 
$ eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)
local::lib is up to date. (2.000024)

Or setup your local environment for once through local::lib.
$ PATH="$PATH:~/perl5/bin"

Additional directories for Perl library.
$ export PERL5LIB=~/perl5/lib/perl5

Options for Module::Build.
$ export PERL_MB_OPT="--install_base '$HOME/perl5'"

Options for Module::MakeMaker.

$ curl -L | perl - -l ~/perl5 App::cpanminus local::lib

Add this to your `.profile` as well.
$ eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)
$ source ~/.profile # reload

Or just use Perl's Docker container image.

Or just use Carton and set everything to local folder.
