Installation failure

[codebach]

Hi there,

Just installed Sylius and getting this error while running install command

In UnitOfWork.php line 1637:
                                                                                                        
  [RuntimeException]                                                                                    
  While adding an entity of class App\Entity\Locale\Locale with an ID hash of "1" to the identity map,  
  another object of class App\Entity\Locale\Locale was already present for the same ID. This exception  
  is a safeguard against an internal inconsistency - IDs should uniquely map to                         
  entity object instances. This problem may occur if:                                                   
                                                                                                        
  - you use application-provided IDs and reuse ID values;                                               
  - database-provided IDs are reassigned after truncating the database without                          
    clearing the EntityManager;                                                                         
  - you might have been using EntityManager#getReference() to create a reference                        
    for a nonexistent ID that was subsequently (by the RDBMS) assigned to another                       
    entity.                                                                                             
                                                                                                        
  Otherwise, it might be an ORM-internal inconsistency, please report it.
