a newbie encounters difficulties in using module

[Rose]

I'm testing the codes obtained from internet:


use Imager;
use Imager:lot;

$plot = Imager:lot->new(Width => 550,
Height => 350,
GlobalFont => 'ImUgly.ttf');

my @X = 0..100;
my @Y = map { sin($_/10) } @X;
my @Z = map { 1+cos($_/10) } @X;

$plot->AddDataSet(X => \@X, Y => \@Z);
$plot->AddDataSet(X => \@X, Y => \@Y,
style=>{marker=>{size => 2,
symbol => 'circle',
color => Imager::Color->new('red'),
},
});

$img = Imager->new(xsize=>600, ysize => 400);
$img->box(filled=>1, color=>'white');

$plot->{'Ylabel'} = 'angst';
$plot->{'Xlabel'} = 'time';
$plot->{'Title'} = 'Quality time';

$plot->Render(Image => $img, Xoff => 40, Yoff => 370);
$img->write(file => "testout.png");

I have already installed Imager module by CPAN.

install Imager

then by

install Color

And when I ran the test.pl by perl test.pl, the following error appears.
What else should I do?

Can't locate Imager/Color.pm in @INC (@INC contains:

There is a module called 'Color' on the CPAN, but it has nothing to do
with Imager. If you meant Imager::Color, then that is part of the Imager
distribution and should have been installed along with Imager.

This makes no sense. Somehow you seem to have installed Imager.pm
without Imager/Color.pm, which should be impossible. I would suggest you
try reinstalling Imager.

Unless she "installed" by copying Imager.pm into the appropriate
directory, which in "I'm testing the codes obtained from internet"
context may not be completely unreasonable as a possibility.

No, but she did say

which ought to have done the right thing.
