title: rvm ruby version and rails server different ruby version
body: <p>It seems rails server uses different ruby then the one that is set up by rvm.</p>
  
  <p>How to make the rails server command use the same ruby as its set up in the rvm?</p>
  
  <p>When I start the rails server, (write rails server in console) it outputs 
  ruby 1.8.7 for ruby version. 
  But when I write</p>
  
  <pre><code> `ruby -v` 
  </code></pre>
  
  <p>to see the ruby version, I get ruby 1.9.3p0 for ruby version.
  Also I have installed rvm and when I type </p>
  
  <pre><code>rvm list 
  </code></pre>
  
  <p>it returns that I'm using ruby-1.9.3-p286, so rvm uses different ruby version than the rails server.
  I need to be able to start rails server with ruby-1.9.3.
  First I have installed ruby 1.8.7 that I installed rvm so I can use ruby-1.9.3.
  But it seems that I still can't use it with rails server.
  Thanks</p>
