Curses in Perl throws errors

Question

Perl

I'm trying to figure out an example

#!/usr/bin/perl -w

use Curses::UI;
    my $cui = new Curses::UI;
    my $win = $cui->add('window_id', 'Window');
    my $listbox = $win->add(
        'mylistbox', 'Listbox',
        -values    => [1, 2, 3],
        -labels    => { 1 => 'One',
                        2 => 'Two',
                        3 => 'Three' },
        -radio     => 1,
    );

    $listbox->focus();
    my $selected = $listbox->get();

crashes on startup

Answer 1

You can just try
perl -MCPAN -e 'install Curses::UI'

Answer 2

1. Search UI.pmin the indicated directories ( /usr/local/lib64/perl5, /usr/local/share/perl5, /usr/lib64/perl5/vendor_perl, /usr/share/perl5/vendor_perl, /usr/lib64/perl5, /usr/share/perl5).
   If you don't find it, it means it wasn't installed or installed in the wrong place (then add the path to INC ).
2. If the file is found, check its read permissions - I recently had the same error due to the program not being able to read the package.
