Perl Database connect not working in .pm file - mysql

Question

In Perl I have connected the database using DBI concept. The database connection and select table query is 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 FROM pj_user where UserEmail=? and UserPassword=?");
$sth->execute($UserEmail,$UserPassword);
my $User_count=$sth->rows;
return $User_count
}
It returns 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.

Try this below code in marketplace.pm file.
use ENV;
my $PERL5LIB= $ENV{'PERL5LIB'};
package Marketplace;
BEGIN {
push(#INC, $PERL5LIB);
};
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 FROM pj_user where UserEmail=? and UserPassword=?");
$sth->execute($UserEmail,$UserPassword);
my $User_count=$sth->rows;
return $User_count
}
