How to change @INC to find Perl modules in non-standard locations

How to change @INC to find Perl modules in non-standard locations


Loading your private Perl module
You have a script and have just started to move some parts of it, out to a new module called My::Module. You saved the module to /home/foobar/code/My/Module.pm.

Your perl script now starts like this:

use strict;
use warnings;
use My::Module;

Can't locate My/Module.pm in @INC (@INC contains:
   /home/foobar/perl5/lib/perl5/x86_64-linux-gnu-thread-multi
   /home/foobar/perl5/lib/perl5
   /etc/perl
   /usr/local/lib/perl/5.12.4
   /usr/local/share/perl/5.12.4
   /usr/lib/perl5 /usr/share/perl5
   /usr/lib/perl/5.12
   /usr/share/perl/5.12
   /usr/local/lib/site_perl
   .).
   BEGIN failed--compilation aborted.


On Linux/Unix when using Bash, you would write

export PERL5LIB=/home/foobar/code
You can add this to the ~/.bashrc to make it always available when you log-in.

On Windows you can set the same in the cmd command window by typing

set PERL5LIB=c:\path\to\dir



The last solution is the most temporary solution. Add a -I /home/foobar/code flag to perl when running the script.

perl -I /home/foobar/code script.pl

This will add /home/foobar/code to the beginning of @INC for this specific execution of the script.
