Why doesn't Curses work in Perl noecho()?

Question

Perl

What am I doing wrong?

use strict;
use Curses;
my $win = Curses->new();
noecho();
$win->addstr(10, 5, 'ggg');
$win->refresh;

At the same time, [email protected]:~$ appears in the terminal window.
Symbols do not appear when trying to type something, but pressing enter produces the result.
