Problema con Django-1.3 beta

Question

Chicos !! Estoy muy entusiasmado con el aprendizaje de django y aprendí un poco sobre Django-1.2, pero luego instalé la versión 1.3, que está bien hasta que ejecuto el servidor usando el comando "python manage.py runserver". Está dando un gran error. No puedo encontrar una manera 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  
    utility.execute()  
    File "/usr/local/lib/python2.6/dist-packages/django/core/management/__init__.py", line 379, in execute 
    self.fetch_command(subcommand).run_from_argv(self.argv) 
    File "/usr/local/lib/python 2.6/dist-packages/django/core/management/__init__.py", line 261, in fetch_command

    File "/usr/local/lib/python2.6/dist-packages/django/utils/importlib.py", line 35, in import_module  
    __import__(name)  
    File "/usr/local/lib/python2.6/dist-packages/django/core/management/commands /runserver.py", line 8, in <module>  
    from django.core.handlers.wsgi import WSGIHandler 
    File "/usr/local/lib/python2.6/dist-packages/django/core/handlers/wsgi.py", line 11, in <module>  
    from django.core import signals 
    File "/usr/local/lib/python2.6/dist-packages/django/core/signals.py", line 1, in <module> 
    from django.dispatch import Signal 
    File "/usr/local/lib/python2.6/dist-packages/django/dispatch/__init__.py", line 9, in <module>  
    from django.dispatch.dispatcher import Signal, receiver  
ImportError: cannot import name receiver  

Answer 1

para evitar problemas como que en el futuro, utilice virtualenv

Answer 2

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