Seems that File::Copy::Recursive is not installed? However, you instantiate a new object ($cp) of type File::NCopy. If that is intentional, you should use that module instead.

  ...
  # use File::Copy::Recursive;  # not used in your example
  use File::NCopy;              # this is the module you're trying to 
+use later

hii Perlbotics
i have tried your suggestion but the error prevails only replacing File/copy/recursive.pm to File/Ncopy.pm
how to install File::Ncopy then

I'm not sure you understand what people and perl are telling you. The perl error means that File::Copy::Recursive is not installed. The module documentation explains how to install it. Use the cpan method so that dependencies are also installed.

Later in your code you have:

my $cp = File::NCopy->new(recursive => 1);

Your code does not have a use line for this module, like you do have for the other modules.

I wouldn't recommend manually moving modules around unless you understand what you are doing. In addition I would suggest you take a step back and review the code you've posted.

Hello mrityunjaynath,

No, stick with the File::Copy::Recursive module. File::NCopy is deprecated, according to its own documentation:

File::NCopy - Deprecated module. Use File::Copy::Recursive instead.

To learn how to install modules, see the Monastery’s Installing Modules tutorials. If you already have App::cpanminus installed, the process is as simple as entering:

>cpanm File::Copy::Recursive
[download]

from the command line.

Another point: Where does $newpath come from? You need to declare and initialise it before it’s used:

...
my $newpath = ...;  # Provide an initial value here
my $source_dirrtl = $newpath . "/rtl";
...

Hope that helps,

how to install File::Ncopy then

See A Guide to Installing Modules from the Tutorials section.

use strict;
use warnings;
use File::Copy;
use File::Basename;
use Cwd;
use Data::Dumper;
use File::Copy::Recursive;

my $source_dirrtl = ("$newpath"."/rtl");
my $target_dirrtl1 = ("$newpath"."/rtl1");



mkdir($target_dirrtl1,0777);



opendir(my $DIRRTL1, $source_dirrtl) || die "can't opendir $source_dir
+rtl: $!";




my $cp = File::NCopy->new(recursive => 1);
my $cp->copy("$source_dirrtl/*",$target_dirrtl1) or die "couldnt copy

Can't locate File/copy/recursive.pm in @INC <@INC contains C:/Perl/site/lib C:/Perl/lib .) at newperlfile2.pl line 9

There are at least three fishy things here:

1. The usual error message uses "(" in front of the second @INC, but your error message has "<" there.
2. The code you posted has use File::Copy::Recursive;, but the error message looks like the code was use File::copy::recursive;.
3. The error message states that the problematic use is in line 9, but line 9 of your posted code is my $source_dirrtl = ("$newpath"."/rtl");. use File::Copy::Recursive; is in line 7.

Please post the actual code and the actual error message. Don't type, use copy-and-paste!

Also note that perl is case sensitive, even when Windows is not. There is a big difference between "use foo::bar;" and "use Foo::Bar;" for Perl, even if both load a file named "Foo/Bar.pm" from somewhere in your module search path (@INC). Always use the module name as it is documented in the module's documentation.
