You'll find them in /usr/lib/perl/{VERSION}/ as well as /usr/lib64/perl/{VERSION}/ . {VERSION} corresponding to the version of Perl. You can get it with perl --version .
If the module is not installed, then: $ perl -e 'use dbi' Can't locate dbi.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.14. 2 /usr/local/share/perl/5.14. 2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .)
if the path is correct, you should see in output the list of perl modules currently installed. Once you have identified the correct path, you can add it to your user's PATH (i.e. if you're using bash shell, edit your . bash_profile and add the path /usr/bin to PATH, like: PATH=$PATH:/usr/bin). locate: not found.
perl -MTime::HiRes -e 'print $INC{"Time/HiRes.pm"}' or perldoc -l Time::HiRes
Mostly I use perldoc to get a location:
$ perldoc -l Module
You can also get module details with the cpan tool that comes with Perl:
$ cpan -D Time::HiRes
Time::HiRes

It even works on modules that you haven't installed:
$ cpan -D Win32::Process

I think maybe I need an XML option like svn.
Note: This solution proposes use of a (self-authored) utility that you must download. While it offers what I believe to be helpful features, installing a third-party solution first is not an option for everyone.
I've created whichpm, a cross-platform CLI (Linux, macOS, Window) that locates installed Perl modules by module (package) name, and optionally reports information about them, including detection of accidental duplicates.
Examples
# Locate the Data::Dumper module.
$ whichpm Data::Dumper
/usr/lib/perl/5.18/Data/Dumper.pm
# Locate the Data::Dumper module, and also print
# version information and core-module status.
$ whichpm -v Data::Dumper
Data::Dumper 2.145 core>=5.005 /usr/lib/perl/5.18/Data/Dumper.pm
# Locate the Data::Dumper module and open it in your system's default text
# editor.
$ whichpm -e Data::Dumper
# Look for accidental duplicates of the Foo::Bar module.
# Normally, only 1 path should be returned.
$ whichpm -a Foo::Bar
/usr/lib/perl/5.18/Foo/Bar.pm
./Foo/Bar.pm
# Print the paths of all installed modules.
$ whichpm -a
Prerequisites: Linux, macOS, or Windows, with Perl v5.4.50 or higher installed.
With Node.js or io.js installed, install the package as follows:
[sudo] npm install whichpm -g
whichpm.chmod +x whichpm.$PATH, such as /usr/local/bin (OSX) or /usr/bin (Linux).If need to find which modules are actually used by your script you can use perl debuggers M command:
[ivan@server ~]$ 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.
I just find another one: http://www.perlmonks.org/?node_id=568730
#!/bin/sh
echo 'print map { sprintf( "%20s : %s\n", $_, $INC{$_} ) } sort keys %INC; print "\n'$1' version : $'$1'::VERSION\n\n"' | perl "-M$1"
the script just print out everything in %INC when you run perl -MSTH::STH
eg:
$ whichpm CGI
CGI.pm : /System/Library/Perl/5.8.6/CGI.pm
CGI/Util.pm : /System/Library/Perl/5.8.6/CGI/Util.pm
Carp.pm : /System/Library/Perl/5.8.6/Carp.pm
Exporter.pm : /System/Library/Perl/5.8.6/Exporter.pm
constant.pm : /System/Library/Perl/5.8.6/constant.pm
overload.pm : /System/Library/Perl/5.8.6/overload.pm
strict.pm : /System/Library/Perl/5.8.6/strict.pm
vars.pm : /System/Library/Perl/5.8.6/vars.pm
warnings.pm : /System/Library/Perl/5.8.6/warnings.pm warnings/register.pm : /System/Library/Perl/5.8.6/warnings/register.pm
CGI version : 3.05
I like to use the V module.
Just install it from CPAN or by installing the package libv-perl on Debian or Ubuntu.
Then use it like this:
$ perl -MV=DBI
DBI
/Users/michiel/.plenv/versions/5.24.0/lib/perl5/site_perl/5.24.0/darwin-2level/DBI.pm: 1.636
Other output example:
$ perl -MV=Time::HiRes
Time::HiRes
/usr/lib/perl/5.18/Time/HiRes.pm: 1.9725
