title: Add a Gem Path?
body: <p>When I run <code>gem environment</code> I get a list which includes the following:</p>
  
  <blockquote>
    <ul>
    <li>GEM PATHS:
    
    <ul>
    <li>/home/rescue/.rvm/rubies/ruby-2.3.3/lib/ruby/gems/2.3.0</li>
    <li>/home/rescue/.gem/ruby/2.3.0</li>
    </ul></li>
    </ul>
  </blockquote>
  
  <p>I'd like to add a path. I see people <a href="https://stackoverflow.com/a/24323310/773263">suggesting</a> to add something like <code>export GEM_PATH = ...</code> to my <code>.bashrc</code> file, but I fear this would replace the existing gem paths.</p>
  
  <p>How can I add another path in addition to the ones that already exist?</p>
