micceo has asked for the wisdom of the Perl Monks concerning the following question:

Hi , i am a newbie to perl , i want to do the following , we have a code in perl which requires the use of many external modules.

Is there a way where i can install all the modules required into a particular directory and make perl point to it . Like a plug and play feature .

I tried looking at local::lib , but could not make much out of it, some help will be appreciated

Regards Ravi

    local::lib does what you want, and the processes of point perl towards the module directory consists of setting the PERL5LIB environment variable (and PATH if the distributions also install scripts), as shown in the SYNOPSIS. The same can be achieved with the -I command line argument.

    The other environment variables are only needed for installing the modules/distributions into the right directory, and not necessary for just using the modules.

    If you describe where you got stuck, it would be easier to help you.

    There are other alternatives, like PAR::Packer and other packers, like cava.

      they may have circular dependencies , so i want to create a folder with all these modules installed , so just make perl pick libraries from that folder. now as there might be dependencies , if i install a module into local folder, the other module might still show dependency error??

        For quick and easy module installation, also see the -L option to cpanm.
