R – How to tell CPAN::Shell to install all dependencies for a module

cpanperl

I currently have this on a script:

 CPAN::Shell->rematein("notest", "install", "$m");

Where $m is a module name the script installs. However, I want the module to install without prompting the user whether additional dependencies should be installed (optional deps or not), how can I do that?

What is your setting for prerequisites_policy in CPAN::Config? That should be follow and not ask.

When you build modules, tell Perl where to install the modules.

For Makefile.PL-based distributions, use the INSTALL_BASE option when generating Makefiles:

perl Makefile.PL INSTALL_BASE=/mydir/perl

You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

For Build.PL-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

You can configure CPAN.pm to automatically use this option too:

% cpan
cpan> o conf mbuildpl_arg '--install_base /mydir/perl'
cpan> o conf commit

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.
