How can I install a CPAN module into a local directory?

Question

I'm using a hosted Linux machine so I don't have permissions to write into the /usr/lib directory.

When I try to install a CPAN module by doing the usual:

perl Makefile.PL make test make install 

That module is extracted to a blib/lib/ folder. I have kept use blib/lib/ModuleName but it still the compiler says module can not be found. I have tried copying the .pm file into local directory and kept require ModuleName but still it gives me some error.

How can I install a module into some other directory and use it?

How do I keep my own module/library directory?

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

I had a similar problem, where I couldn't even install local::lib

I created an installer that installed the module somewhere relative to the .pl files

The install goes like:

perl Makefile.PL PREFIX=./modulos make make install 

Then, in the .pl file that requires the module, which is in ./

use lib qw(./modulos/share/perl/5.8.8/); # You may need to change this path use module::name; 

The rest of the files (makefile.pl, module.pm, etc) require no changes.

You can call the .pl file with just

perl file.pl
