title: I can't run my Rails web server
body: <p>I have installed ruby193 and I've installed rails via the command prompt. However, whenever I try the command:</p>
  
  <pre><code>ruby script/server
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>ruby: No such file or directory -- script/server (LoadError)
  </code></pre>
  
  <p>I checked my script folder and all it has is a file called rails.</p>
  
  <p>I'm very new to Ruby on Rails and I'm not entirely sure if I've installed everything correctly. Is there an easy way to check what I have installed?</p>
