In PERL I have connet the database using DBI concept. The database connection & select table query everything working fine in .pl file. But i have run the DBI database connection code in .pm file. It's not working.

Please review code.

Sample.pl (It's working fine)

 use DBI;
my $driver = "mysql"; 
    my $database = "marketplace_perl";
    my $dsn = "DBI:$driver:database=$database";
    my $userid = "root";
    my $password = "root";
    my $dbh = DBI->connect($dsn, $userid, $password );
    my $dbh=connect_db();
        my $sth = $dbh->prepare("SELECT UserEmail,UserPassword FROM pj
+_user where UserEmail=? and UserPassword=?");

        $sth->execute($UserEmail,$UserPassword);

Marketplace.pm (It's not working)

package Marketplace;
use DBI;
    sub connect_db {
        my $driver = "mysql"; 
        my $database = "marketplace_perl";
        my $dsn = "DBI:$driver:database=$database";
        my $userid = "root";
        my $password = "root";
        my $dbh = DBI->connect($dsn, $userid, $password );
       return $dbh;
    }

    sub login_marketplace { 

    my $dbh=connect_db();
            my $sth = $dbh->prepare("SELECT UserEmail,UserPassword FRO
+M pj_user where UserEmail=? and UserPassword=?");

            $sth->execute($UserEmail,$UserPassword);
            my $User_count=$sth->rows;
    return $User_count

    }

It's rertun the error message of "Failed to access class (Marketplace): Can\'t locate DBI.pm in @INC (you may need to install the DBI module)"

Please let me know how to fix the DB issue.
