Installing specific versions of CPAN modulesby Mutant (Priest)
|on Aug 08, 2008 at 14:34 UTC||Need Help??|
Mutant has asked for the
wisdom of the Perl Monks concerning the following question:
I'm not sure if this is possible, but I'm trying to create a way to build a set of CPAN modules of a specific version so that this build can be repeated (e.g. on another platform).
The approach I was hoping to take was:
I was hoping CPAN.pm would help me, but it seems geared towards installing only the latest version of a module. i.e. there's no way to specify a specific version to download/install. You can give it a specific distribution name, but older versions won't be in the index, so you can't find out which modules they contain, and therefore can't find out if they've already been installed on the system.
In case it's not immediately obvious, the reason I need to do this is so that I can maintain a set of CPAN modules across multiple platforms (i.e. different OSes / CPUs) which may be added to at a later date, requiring the set of modules to be re-built. For paranoid reasons, the modules need to be the same versions as exist on the other platforms.
Anyone have any ideas how to solve this?
