Update cpan modules

Depending on the Operating System and which Perl distribution you have, the specific instructions differ. In order to make the examples clearer, let's try to install the module called Try::Tiny. Both have the Download links that we won't click on. Also, in normal circumstances, the cpan client is expecting the full name of the module, not one part of the name, and not the name of the zip-file. So cpan Path or cpan Tiny will attempt to install different modules. One called Path, the other one called Tiny.

Please note, this too is case sensitive! It can also be out-of date carrying older versions of the modules. GitPerl TBD. Cygwin Perl TBD.

Okay, this isn't as cool as cpanminus , but at least you don't have to download anything to get this to work. For Strawberry Perl, try: cpan -u.

For regular Perl too. From the man page: -u Upgrade all installed modules. Blindly doing this can really break things, so keep a backup. The option cpan -u how long does it take to update?

It works fine for me. Matthias Munz Matthias Munz 3, 4 4 gold badges 26 26 silver badges 44 44 bronze badges. The Module Include Path section of the interface displays the location where the system will store your modules.

If you wish to reference those modules from other modules or programs, use this include path. The Using Your Perl Module s section of the interface lists a choice of code that you must include in the top of your Perl script.

This code represents the location of Perl that the system will use to run the script. If you want to see what's changed for modules that require upgrades, use cpan-listchanges. For more information on module installation, please visit the detailed CPAN module installation guide. This script can be integrated with the cpanm command.
