Question

I know it’s easy to install a module with ‘force’ using CPAN from command prompt. I am trying to achieve same through the script:

use CPAN;
eval "use Filesys::DiskSpace" or do {
    CPAN::install("Filesys::DiskSpace");
};

Is there any way to add the option ‘force’ to the code?
I am having the following error while compiling the module:

  make test had returned bad status, won't install without force

The warnings could not be serious, so I would like to proceed with the installation.
Thanks.

So long as you Really Know What You Are Doing:

eval "use Filesys::DiskSpace; 1" or do {
    CPAN::Shell->force("install","Filesys::DiskSpace");
};

The use builtin doesn’t return anything useful, even when it is successful, so it is necessary to include the “;1” in the string eval.
