How can I find out where a Perl module is installed?

Question

How do get the path of a installed Perl module by name, e.g. Time::HiRes?

I want this just because I have to run my perl script on different nodes of a SGE

Answer 1

In OSX you can use:

perl -e 'print join("\n",@INC)'

The result should be the location of your lib.

Then add this code in your Perl code:

use lib '/your/folder/location/to/lib';

Answer 2

If need to find which modules are actually used by your script you can use perl debuggers M command:

[ivan@server ~]$ perl -d your_script.pl
...

Debugged program terminated.  Use q to quit or R to restart,
  use o inhibit_exit to avoid stopping after program termination,
  h q, h R or h o to get additional info.

DB M
'AutoLoader.pm' => '5.60 from /usr/lib/perl5/5.8.8/AutoLoader.pm'
'Carp.pm' => '1.04 from /usr/lib/perl5/5.8.8/Carp.pm'
...

This will help in case when you have modules with same names but in different folder.

perl -MTime::HiRes -e 'print $INC{"Time/HiRes.pm"}' or perldoc -l Time::HiRes
