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

Is there a way to invoke cpanp (e.g. from a perl script) so that it will install a list of modules, automatically add any prerequisites that are missing, and abort if it can't find one or more prerequisites?

    You can use the simplified CPANPLUS module interface, or CPANPLUS::Backend, the object-oriented way.

    # Simple version
use CPANPLUS;

for my $mod (qw/Acme::Drunk Acme::Bleach/) {
    install($mod);
}

# Complex version, probably better
use CPANPLUS::Backend;

my $cb = CPANPLUS::Backend->new();
$cb->install( modules => [ 'Acme::Drunk', 'Acme::Bleach' ] );

    CPANPLUS installs prerequisites automatically, provided you have the configuration option 'prereqs' set to 1.

    Yes, use 
    system 'cpanp', '--install', '--prereqs',... 'Foo::Bar'
