Problema con django-1.3 beta

Question

Ragazzi!! Sono davvero entusiasta di apprendere Django e ho imparato un po 'su Django-1.2 ma poi ho installato la versione 1.3, il che è OK fino a quando non eseguo il server usando il comando "Python Manage.py Runserver". Sta dando un enorme errore. Non riesco a trovare un modo per risolverlo. E l'errore è dato come:

Traceback (most recent call last):    

  File "manage.py", line 11, in <module>    
    execute_manager(settings)    
  File "/usr/local/lib/python2.6/dist-packages/django/core/management/__init__.py", line 438, in execute_manager    
    utility.execute()    
  File "/usr/local/lib/python2.6/dist-packages/django/core/management/__init__.py", line 379, in execute

    from django.dispatch.dispatcher import Signal, receiver    
ImportError: cannot import name receiver    

Answer 1

Per evitare problemi come quello in futuro, usa virtualenv

Answer 2

Questo può accadere se hai due versioni installate. Elimina django (/usr/local/lib/python2.6/dist-packages/django) elimina l'intera cartella. Ora reinstalla Django 1.3 e dovrebbe funzionare.
