Need to configure perl

Question

I was going to run a perl program and then I got this error message:

Can't locate JSON.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at ./po2json line 23.
BEGIN failed--compilation aborted at ./po2json line 23.

I supposse there is some JSON module that needs to get installed perhaps via cpan. Do you have a suggestion for how to enable it?

Thanks

Update

So I could install the JSON module but now I get another error message

Can't locate Locale/PO.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at ./po2json line 24.
BEGIN failed--compilation aborted at ./po2json line 24.

Solution 1

On Ubuntu 10.04 this file can be found in the liblocale-po-perl package:

$ apt-file search Locale/PO.pm
liblocale-po-perl: /usr/share/perl5/Locale/PO.pm

Another way to have worked this out:

$ apt-cache search Locale::PO
liblocale-po-perl - Locale::PO perl module

which you may prefer since apt-file is not installed by default.

Solution 2

For JSON.pm on ubuntu system, you should install libjson-perl package:

apt-get install libjson-perl

You can find which ubuntu package holds your file thanks to:

apt-file search JSON.pm
