title: Ruby Gem Twitter - certificate verify failed (Twitter::Error::ClientError)
body: <p>I am trying to use the ruby gem 'twitter' but for unknown reasons I cant get it to work. </p>
  
  <p>Here is the .rb code:</p>
  
  <pre><code>require 'twitter'
  
  puts "Greetings, World!"
  puts "Checkpoint 1"
  Twitter.configure do |config|
    config.consumer_key = "xxxxxxx" #removed for posting
    config.consumer_secret = "xxxxxxx" #removed for posting
    config.oauth_token = "xxxxxxx" #removed for posting
    config.oauth_token_secret = "xxxxxxx" #removed for posting
  end
  Twitter.verify_credentials
  puts "Checkpoint 2"
  </code></pre>
  
  <p>and I get the following error:</p>
  
  <pre><code>Greetings, World!
  Checkpoint 1

  <p>I am a ruby newbie and I cant make sense of the client error... perhaps I am missing something. I have also confirmed my Oauth credentials are working in python.</p>
  
  <p>Thanks in advance and I look forward to your help. </p>
