"Permission denied" when download from script(ruby) file

Question

I want to download a project's dependencies from a script file

in tutorial said: run this comment to download

./download-dependencies core

my way was like this:

$ cd Documents/ImageProccesing/
$ ./download-dependencies core
bash: ./download-dependencies: Permission denied    
$

I did this too,but....

$ sudo -i    
[sudo] password for amir2:     
# cd /home/amir2/Documents/ImageProccesing/    
# ./download-dependencies core    
-bash: ./download-dependencies: Permission denied    
#

in addition... first of download-dependencies file is like this:

#!/usr/bin/ruby

$modules = [:core,
            :images2002,
            :images2004]

def usage
  puts "Usage: ./download-dependencies <#{$modules.join('|')}>"
end
