Problema con django-1.3 beta

Question

¡¡Tipo!! Estoy realmente entusiasmado al aprender a Django y aprendí un poco en Django-1.2, pero luego instalé 1.3 Versión, que está bien hasta que ejecute el servidor usando el comando "Python Manage.py RunServer". Está dando un gran error. No puedo entender una forma de resolver esto. Y el error se da como:

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

ImportError: cannot import name receiver    

Answer 1

Para evitar problemas como ese en el futuro, use virtualenv

Answer 2

Esto puede suceder si tiene dos versiones instaladas. Eliminar django (/usr/local/lib/python2.6/dist-packages/django) simplemente elimine la carpeta completa. Ahora reinstale Django 1.3 y debería funcionar.
