title: Is there a way to update RubyGems offline?
body: <p>I am trying to install Ruby + WATIR to a Windows server which is in an isolated environment.  Typically I would run the ruby installer followed by these two commands:</p>
  
  <p>1) gem update --system</p>
  
  <p>2) gem install watir</p>
  
  <p>This is as per the instuctions <a href="http://wtr.rubyforge.org/install.html" rel="noreferrer">here</a></p>
  
  <p>The server I am now trying to install to does not have internet connectivity.  This causes the commands above to fail.</p>
  
  <p><em>Is there a way I can download the update packages required and copy them to the server to install locally?</em></p>
