Undefined subroutine &main::remove_tree call - perl

I am writing a perl script that would send email about a the number of open cases and at the sametime will delete a directory which is more than 30 days old.
$age = -M;
if($age > 30)
{
remove_tree ($_);
}
This is what I am doing.Teh script was running fine but after 30 days It stopped running,not deleting the old directories and throws the following error.
Undefined subroutine &main::remove_tree called at /var/www/cgi-bin/remedy-case-
management/remedy-open-cases-script.pl line 35.
Not sure How i solve this.
I removed the paranthesis from remove_tree line and it throws error as follows.
Can't call method "remove_tree" without a package or object reference at /var/www/cgi-bin/remedy- case-management/remedy-open-cases-script.pl line 35.
Can anyone let me know what error i am making here?Thanks.

remove_tree is a function in File::Path.
Be sure to include that module before using the function:
use File::Path qw(remove_tree);

It seems you removed or commented out a line similar to
use File::Path qw{ remove_tree };
See File::Path.

Does package compiled partially? How to prevent this?

I have code (some lines are removed):
package MaitreD::Command::bank_statement;
use Mojo::Base 'Mojolicious::Command';
sub run {
...
my $payments = read_file( $file ); # line 58
...
}
use XBase; # line 174
sub read_file {
...
}
1;
I run my application. And then do two http requests to this app. Controller runs this command as:
$c->app->commands->run( bank_statement => $upload );
I get next error (this one is expected):
Can't locate XBase.pm in #INC (you may need to install the XBase module) (#INC contains: /opt/monkeyman/lib /opt/monkeyman/local/lib/perl5/x86_64-linux /opt/monkeyman/local/lib/perl5 /opt/monkeyman/lib /opt/monkeyman/local/lib/perl5/5.24.1/x86_64-linux /opt/monkeyman/local/lib/perl5/5.24.1 /opt/monkeyman/local/lib/perl5/x86_64-linux /opt/monkeyman/local/lib/perl5 /opt/perlbrew/perls/perl-5.24.1/lib/site_perl/5.24.1/x86_64-linux /opt/perlbrew/perls/perl-5.24.1/lib/site_perl/5.24.1 /opt/perlbrew/perls/perl-5.24.1/lib/5.24.1/x86_64-linux /opt/perlbrew/perls/perl-5.24.1/lib/5.24.1 .) at /opt/monkeyman/lib/MaitreD/Command/bank_statement.pm line 174.
BEGIN failed--compilation aborted at /opt/monkeyman/lib/MaitreD/Command/bank_statement.pm line 174.
Compilation failed in require at (eval 2620) line 1.
But when I did second request I got different error:
Undefined subroutine &MaitreD::Command::bank_statement::read_file called at /opt/monkeyman/lib/MaitreD/Command/bank_statement.pm line 58.
How MaitreD::Command::bank_statement::run could be run from controller if module MaitreD::Command::bank_statement compilation failed?
If understand correct the module MaitreD::Command::bank_statement was compiled partially to 174 line. So next http request to app can call MaitreD::Command::bank_statement::run and when 58 line is reached I get Undefined subroutine &M::C::b::read_file called because nothing is compiled after 174 line.
How to prevent partial compilation?
I want if there are some errors occur then nothing from MaitreD::Command::bank_statement should be available
It seems you should be focusing on ensuring use XBase actually succeeds, beause presumably it's there for a reason and it's needed for the rest of the program to work.
Why does it fail? Fix that first and the partial compilation isn't a problem.
In this case, why can't perl find the module?
Is it possible the Command::bank_statement class isn't used directly, but only when it's being run, so maybe the current working directory changed between the program start and the time $c->app->commands->run( bank_statement => $upload ); was called?
If that's the case, try loading the command class earlier. e.g. add this to the Mojo application class (probably something like lib/MaitreD.pm:
use MaitreD::Command::bank_statement;

Perl - Webmin - "strict refs" in use

I have a problem with module for Webmin, and I just want to resolve it with your help!
This is error that I get when I try do add new VirtualHost to Nginx module:
Error - Perl execution failed
Can't use string ("/home/www/website") as an ARRAY ref while "strict refs" in use at virtualmin-nginx-lib.pl line 247.
I don't really know where is problem, because I'm not Perl programmer.
There is a file: Pastebin
This seems to be a known issue:
http://www.virtualmin.com/node/23565
The solution seems to be adding the following line near the end of /etc/nginx/nginx.conf, within the http { ... } block:
include /etc/nginx/sites-enabled/*;

Dancer DBIC Could not load schema_class

I have a Dancer app that is working. I am using DBIC for the database.
I want to add some tables to the database, and so I created new files for those. However, now when I restart the app, I get the following errors
Error while loading ././bin/app.pl: Could not load schema_class MyApp::Schema at /usr/local/share/perl/5.14.2/Dancer/Plugin/DBIC.pm line 42.
Compilation failed in require at ././bin/app.pl line 5.
BEGIN failed--compilation aborted at ././bin/app.pl line 5.
When I remove the new files, everything works fine.
Here is my Schema.pm file
package MyApp::Schema;
# Created by DBIx::Class::Schema::Loader
# DO NOT MODIFY THE FIRST PART OF THIS FILE
use strict;
use warnings;
use base 'DBIx::Class::Schema';
__PACKAGE__->load_namespaces;
1;
Where can I get more information about the error and what I did wrong?
Since you are using __PACKAGE__->load_namespaces, all new classes will loaded, which explains why the simple existence of the new class files cause an error. If there is a syntax error in your new class files, then loading the schema will die.
You can use perl -c on the new class files to ensure they will compile and get a better idea of the problem if they do not.

I keep getting failures installing modules at BEGIN { plan tests => 5 }. What do I need to get past this?

The module it's failing to install is JSON::XS. Really it's failing to install anything
that has the following code:
BEGIN { plan tests => 5 };
From the build.log:
syntax error at t/04_dwiw_encode.t line 13, near "plan tests"
The offending line:
13 BEGIN { plan tests => 5 }
I read that there's a problem with Test.pm but there are quite a few modules
using it and furthermore this just started happening recently.
I just tried reinstalling perlbrew and also tried updating outdated modules
but I keep getting the same failures.
Any one have an idea what might have caused this and how to fix it?
I suspect you either have an older-than-expected version of the Test module, or you created your own module named Test.pm and it's getting picked up instead of the expected module.
You can address the first issue by upgrading Test.
cpan Test
You should address the second issue by renaming your Test.pm to something else, but you might also be able to address it by changing directory and temporarily clearing the PERL5LIB env var.
pushd / ; PERL5LIB= cpan JSON::XS ; popd

Open2 Api failure while installing Mead software

I am running into some issues trying to install a software called MEAD . I would appreciate if someone could have alook .
I get the following error while installing
/mead/bin # ./mead.pl GA3
Using system rc-file: /home/karosh/mead/bin/../.meadrc
Warning: Can't find user rc-file
Cluster: /home/karosh/mead/bin/../data/GA3/GA3.cluster
open2: exec of /home/karosh/mead/bin/driver.pl failed at ./mead.pl line 230
THe mead software is not written by me so I have not changed any of the perl scrips . I line 230 in the driver.pl file is
sub run_mead {
my %options = #_;
my $reader = FileHandle->new();
my $writer = FileHandle->new();
unless ( open2($reader, $writer, "$FindBin::Bin/driver.pl") ) {
die "Unable to run MEAD.\n";
}
...
...
}
Does this error mean that open2 was not found . The mead folks have put the following line in the file:
use strict;
use File::Spec;
use FileHandle;
use IPC::Open2;
Or does it mean that i need to install the rpm that contains the API . I see that this API is a part of the core perl bundle http://perldoc.perl.org/IPC/Open2.html. So why was it not installed ? Do i need to install perl again .
Someone has earlier faced this problem - http://www.summarization.com/~radev/mead/email/0160.html but the solution is not working for me . I find no Perl files with the incorrect perl directives . The mead team has been dissolved and there is no one to ask questions but I need to use this software.
I think if some one can explain me the meaning of the error than I can do deeper. Anyone?
It probably means that .../driver.pl doesn't have execute permission. Change the file permissions or call it like
open2($reader, $writer, "perl $FindBin::Bin/driver.pl")
open2($reader, $writer, "$^X $FindBin::Bin/driver.pl")
