I'm trying to run the simple "MongoDB:Tutorial" tutorial:
http://search.cpan.org/dist/MongoDB/lib/MongoDB/Tutorial.pod
My goal is to connect to a MongoDB database from a Perl script. I've installed MongoDB using cpanm:
$ sudo cpanm MongoDB
MongoDB is up to date. (0.501.1)
I created a simple Perl script called loadRaw.pl
:
use strict;
use warnings;
use MongoDB;
use MongoDB::Connection;
use MongoDB::OID;
print "hello\n";
When I try to run the script, I get a bunch of errors:
$ perl ./loadRaw.pl

It seems like the MongoDB Perl module (specifically, the Cursor.pm
file) has some syntax errors. The first batch of problems (those related to the confess
keyword) are solved if I add the line use Carp;
to the top of Cursor.pm
. However, I don't think I should have to do this, and instead I'm doing something else incorrectly. Also, the second batch of errors (those related to the has
keyword) are not solved by including Carp
.
Has anyone else experienced this? Any ideas?
