Perl module not found

How do I solve a Perl module not found error?

In most cases, you can check whether a module exists using the command:
perldoc -l Module::Name

For example,

$ perldoc -l Math::CDF
/gpfs/runtime/opt/perl/5.18.2/lib/site_perl/5.18.2/x86_64-linux-thread-multi/Math/CDF.pm

If the module is installed the path will be displayed. If it does not exist, you can email support@ccv.brown.edu.

There is also a chance that you are using the "wrong" Perl to execute your script. Check the first line of the script. Does it say:

 #!/usr/bin/perl

If so, you are using the default Perl executable and this may produce errors due to conflict between Perl versions. Changing the first line to:

 #!/usr/bin/env perl

will use the first Perl executable in your PATH environment variable instead, which will be any loaded Perl module.

@paulstey I changed the last bit from the version on the docs. I cut out the version numbers because it may be hard to keep UpToDate. Let me know if it still makes sense. Thanks!
