I am trying to run a bioinfo program (Simple Synteny), but it just won't initiatialize Magick

Question

The program can be found in: https://www.dveltri.com/simplesynteny/versions/

I'm running the SyntenyDrawer.rb

with the lines:

sudo ruby ~/GenomasdeTribolium/SimpleSynteny_LATEST/SyntenyDrawer.rb ~/GenomasdeTribolium/demofiles/cmap

Keep getting this answer:

Checking for CMAP Files in DIR: /home/vieira/GenomasdeTribolium/demofiles/cmap
Found: teste1_fwd.cmap
Found: teste2_fwd.cmap
Traceback (most recent call last):

/home/vieira/GenomasdeTribolium/SimpleSynteny_LATEST/SyntenyDrawer.rb:1442:in `block in <main>': undefined method `density=' for main:Object (NoMethodError)

I have installed the packages via:

sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev

sudo apt-get install ruby

gem install --user rmagick (and also add the PATH via export PATH="/home/vieira/.gem/ruby/2.7.0/bin:$PATH" and then gem install --user rmagick and also tried gem install rmagik)

gem install --user bio (also performed the same procedure as above)

The lines regarding the error are:

line 36:  require 'rmagick'
line 37:  include Magick

line 1442: canvas = Magick::Image.new(img_width, img_height) {self.density = $DPI}

Can anyone figure out how to solve it? Please?

I was trying to run the program to build an image file with the relevant details for genomic analysis.
