Missing Perl module error

Hi All,

Thanks for the support. I am trying to run a Perl Script and it is showing the following error. It says that it cannot find the Date/Calc.pm. My question is where should I place the Date module and what is @INC? Any help would be greatly appreciated.

Thanks!
Jenni

Can't locate Date/Calc.pm in @INC (@INC contains: /usr/lib/perl5/vendor_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.5 /usr/lib/perl5/5.8.5/i386-linux-thread-multi /usr/lib/perl5/5.8.5 /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.4/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.3/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.2/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.1/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl/5.8.4 /usr/lib/perl5/site_perl/5.8.3 /usr/lib/perl5/site_perl/5.8.2 /usr/lib/perl5/site_perl/5.8.1 /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.4/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.3/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.2/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.1/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.4 /usr/lib/perl5/vendor_perl/5.8.3 /usr/lib/perl5/vendor_perl/5.8.2 /usr/lib/perl5/vendor_perl/5.8.1 /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl .) at /opt/Crawler/crawler.pl line 9.

if this is a TeamSite server you should be putting your modules in the %iw-home%/iw-perl/ folder, most likely grouped in a sub folder. otherwise, if this is not a teamsite server then it should go to where ever your perl folder is located on the server.

The @INC is an array that contains the paths of all the folders that perl should look in for perl modules/scripts. If the folder location where you're storing your perl modules is not in this list then you need to add it to the environment path for your system.

Hi Jamik,

We are not using TeamSite server.

I see multiple directories for @INC. Can I just place the Date module at any one of the locations and it would solve my issue?

Thanks!

Yes, you can do that. I would still suggest trying to consolidate your PMs into a central location and clean up the @INC so it's not pointing to a bajillion places. that way you have everything in one spot and you don't have to search all over your server for where a certain PM is or where you need to place a PM.

Not necessarily. Some modules are built with a make file. Others can just be copied. Some have additional dependencies.

You would be better off using one of the normal install tools (like cpan) to install the PM. It will find dependencies.

Hi Jamik,

I added Date folder to /usr/lib/perl5/vendor_perl. I am still getting the same error. Any suggesstions? How do i add/delete the @INC values?

Thanks!

I forgot to mention what Nipper does in his post. If you're on a *nix machine (which looks to be the case) you should be using CPAN to install modules on your machine because of the dependencies that some modules may have as Nipper noted. If you're on a windows machine I suggest using ActiveState's ActivePerl (note: not all CPAN modules are available for windows)

Simple modules that don't require compilation you can generally move those around by hand but the more complex ones need to be installed (usually ones written with some C code) but it's generally a good idea to use CPAN or ActivePerl (depending on environment) to do the install of the PM
