Ruby Question

`require': cannot load such file -- HTTParty (LoadError)

First off I'm a Newbie in regards to Ruby, and I'm following the simple tutorial on https://www.distilled.net/resources/web-scraping-with-ruby-and-nokogiri-for-beginners/

I have a

test.rb
file that contains the following:

require 'rubygems'
require 'Nokogiri'
require 'HTTParty'
require 'Pry'
require 'csv'

# this is how we request the page we're going to scrape
page = HTTParty.get('https://newyork.craigslist.org/search/pet?s=0')
Pry.start(binding)


When I try to run the ruby test script, I get the following error:

pjw@ubuntu:~/ruby/test$ ruby test.rb
/home/pjw/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- HTTParty (LoadError)
from /home/pjw/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from test.rb:1:in `<main>'


I've verified HTTParty works properly by running:

httparty "https://newyork.craigslist.org/search/pet?s=0"


The problem seems to be the
require
statement. If I mix the order or the required gems, the first one gives the same error as above. I've searched online and can't seem to find what I'm missing...
