Creating a simple csv file: No such file or directory @ rb

I am struggling with a very basic task of creating a csv file from the ruby core library. I am basically copying the code almost exactly:

require 'csv'
CSV.open("~/Desktop/codes.csv", "wb") do |csv|
  csv << ["id", "code"]
  csv << ["TESTCODE01", "CODE001"]
end

And when I execute this code, I receive the following error:

csv.rb:641:in `initialize': No such file or directory @ rb_sysopen - ~/Desktop/codes.csv (Errno::ENOENT)

I have an empty csv file that I'm trying to write to on my Desktop but somehow it errors out. I know this has to be something simple that I'm not doing. Can someone point out what Im doing wrong? Thank you.

You're expecting something like shell expansion but you're not running in a shell. Instead do something on the order of:

require 'csv'
CSV.open(Dir.home   "/Desktop/codes.csv", "wb") do |csv|
  csv << ["id", "code"]
  csv << ["TESTCODE01", "CODE001"]
end
