Perl Tutorials - Herong's Tutorial Examples

∟Perl on macOS Computers

∟Configure CPAN Shell

This section provides a tutorial on how to configure CPAN Shell to manage Perl module installations on macOS.

CPAN (Comprehensive Perl Archive Network) is is a repository of over 250,000 Perl modules, written by over 12,000 contributors. See CPAN Website at https://www.cpan.org for more information.

CPAN Shell is Perl module that provides a shell interface to manage installations of CPAN Perl modules.

To use CPAN shell, you need to configure it first. Here is what I did on my macOS system.

1. Run the "perl -MCPAN -e shell" command: 

herong$ perl -MCPAN -e shell

CPAN.pm requires configuration, but most of it can be done automatically.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Would you like to configure as much as possible automatically? [yes] yes
...

Warning: You do not have write permission for Perl library directories.

To install modules, you need to configure a local Perl library directory or
escalate your privileges.  CPAN can help you by bootstrapping the local::lib
module or by configuring itself to use 'sudo' (if available).  You may also
resolve this problem manually if you need to customize your setup.

What approach do you want?  (Choose 'local::lib', 'sudo' or 'manual')
[local::lib] sudo

Autoconfigured everything but 'urllist'.

Now you need to choose your CPAN mirror sites.  You can let me
pick mirrors for you, you can select them from a list or you
can enter them by hand.

Would you like me to automatically choose some CPAN mirror
sites for you? (This means connecting to the Internet) [yes] yes

Trying to fetch a mirror list from the Internet
Fetching with LWP:
http://www.perl.org/CPAN/MIRRORED.BY
Fetching with LWP:

Autoconfiguration complete.

You can re-run configuration any time with 'o conf init' in the CPAN shell
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v2.00)
Enter 'h' for help.
cpan[1]>

Now you can use the CPAN module to install and manage other perl modules from the CPAN repository. See CPAN tutorials for more details.
