Cannot print dictionary items?

[Behinder]

This is my simple code:
#encoding: UTF-8
#!/usr/bin/env ruby
require "net/http"
require "docopt"
require "uri"

doc=<<DOCOPT

Usage:
screengrab (application_id) [-c=(us|pl|de|gb|au)]
screengrab -h|--help
screengrab --version

Options:
-h|--help Show this help
--version Show version
-c=(us|pl|de|gb|au) Lookup in specific Store.

DOCOPT

begin
require "pp"
options = Docopt::docopt(doc,version:"1.0")
pp options
rescue Docopt::Exit => e
puts e.message
exit 1
end

no matter what I do, command pp options do not produce any dictionary on screen

I tried to run test example by ruby -d and got weird results:

Exception LoadError' at /Users/sebastian/.rvm/rubies/ruby-2.5.1/lib/ruby/2.5.0/rubygems.rb:1388 - cannot load such file -- rubygems/defaults/operating_system Exception LoadError' at /Users/sebastian/.rvm/rubies/ruby-2.5.1/lib/ruby/2.5.0/rubygems.rb:1397 - cannot load such file -- rubygems/defaults/ruby

WTF?

This is something I struggled with but I was able to get around it by using pry.

Sample code:
require "docopt"
require "pry"

doc = <<DOCOPT
Usage:
#{__FILE__} <country> <state> <city> <street_name>
Options:
-h --help show this help message and exit
DOCOPT

begin
require "pp"
pp = Docopt::docopt(doc)
binding.pry
rescue Docopt::Exit => e
puts e.message
end

The output will be something like this:
19: DOCOPT
20:
21: begin
22: require "pp"
23: pp = Docopt::docopt(doc)
=> 24: binding.pry
25: rescue Docopt::Exit => e
26: puts e.message
27: end
28:
29: # SETUP for calls.

[1] pry(main)> pp
=> {"<country>"=>"usa",
"<state>"=>"tx",
"<city>"=>"houston",
"<street_name>"=>"Clark county"}
