Re: Can't locate object method "require_version"

perldoc perldiag contains extended explainations of all of Perl's diagnostic messages. Maybe that will help you.
Can you demonstrate a short (<10 line) program that exhibits this behaviour for you?

The page that you linked me to indicated the following. Please could someone further explain this for me.
Can't locate object method "%s" via package "%s"
(F) You called a method correctly, and it correctly indicated a package functioning as a class, but that package doesn't define that particular method, nor does any of its base classes. See perlobj.

Martin,
I expect that I have not correctly installed DBI. Or there is a compatibility problem with Win XP.
The code in question is:
use DBI;

Win,
Is that all the code you have in this script? I have never had any problems installing DBI on Windows 2000 or XP. Check out Installing Modules if you need help installing modules.

I expect so, too :-)
Assuming you have installed ActivePerl, try entering (while connected to the internet):
ppm install DBI
If you get complaints that DBI is already installed then run:
ppm remove DBI
followed by:
ppm install DBI
Cheers,
Rob

What version of Perl (perl -v), DBI (perl -MDBI -le "print DBI->VERSION") and Exporter (perl -MExporter -le "print Exporter->VERSION") are you using?

Sounds like you're missing @ISA = qw( Exporter ); in a module using Exporter. require_version is called by (and provided via inheritance by) Exporter to handle use Module version;

You should only see that error if you do something like use DBI 1.50; and if this wasn't supported by DBI. Re^3: Can't locate object method "require_version" was partially a trick question to make sure you weren't doing this.
I looked into DBI and I can't find what would cause this problem. Exporter is loaded, and Exporter is in @DBI::ISA.
Furthermore, line 22 is in the POD, so the error message is wrong, or the DBI.pm you are executing is not the DBI.pm you think you are executing. I see perl is trying to load C:\Perl\lib\DBI.pm, but I would expect DBI to be located at C:\Perl\site\lib\DBI.pm. Try renaming C:\Perl\lib\DBI.pm, C:\Perl\lib\DBI and C:\Perl\lib\DBD to something else temporarily.
PS - I'm using ActivePerl 5.8.8 (like you), Exporter 5.58 (like you) and the DBI obtained using using ppm (1.50), and I have no problem.
