perl - How do I tell CPAN to install all dependencies?

Question

How do I tell CPAN to install all dependencies?

I tried setting these in cpan:

cpan> o conf prerequisites_policy follow
cpan> o conf commit

I still had to answer "y" a couple of times (but fewer than before it feels like).

Is there a way to get it to always go ahead and install? I want to make it unattended.

It would seem that I want a flag to always trust CPAN to do the right thing, and if it suggests an answer I would like to follow it (always hit Enter when it asks something).

Try setting PERL_MM_USE_DEFAULT like so:

PERL_MM_USE_DEFAULT=1 perl -MCPAN -e 'install My::Module'

It should make CPAN answer the default to all prompts.
