title: Doctrine Error: "An exception occured in driver (...)"
body: <p>I am new at Simphony. The tutorial that I am following to get started with, tell me to do, on my Terminal, this command:</p>
  
  <pre><code>php app/console generate:doctrine:entity
  </code></pre>
  
  <p>When I execute the command, this error occurs:</p>
  
  <pre><code>[Doctrine\DBAL\Exception\ConnectionException]                                     
  An exception occured in driver: SQLSTATE[HY000] [2002] No such file or directory  
  
  [Doctrine\DBAL\Driver\PDOException]               
  SQLSTATE[HY000] [2002] No such file or directory  
  
  [PDOException]                                    
  SQLSTATE[HY000] [2002] No such file or directory 
  </code></pre>
  
  <p>I have searched and I did not find a solution.</p>
