While running the php "app/console faker:populate" I am getting following error:

 [Symfony\Component\Debug\Exception\ContextErrorException]                    
  Catchable Fatal Error: Argument 1 passed to Faker\ORM\Doctrine\EntityPopula

Answer 1

EntityManagerInterface was added in Doctrine 2.4 and the master branch of Faker is already depending on it. So, either upgrade Doctrine to 2.4 or downgrade Faker from master to 1.2.
