Django的manage.py執行syncdb錯誤

Question

您好我是很新的Django和我一直保持打字時的「manage.py執行syncdb」

Traceback (most recent call last): 
    File "C:\Users\B3dog\Desktop\MyWebsite\mysite\manage.py", line 10, in <module> 

    execute_from_command_line(sys.argv) 
    File "C:\Python34\lib\site-packages\django-1.8-py3.4.egg\django\core\managemen 
t\__init__.py", line 330, in execute_from_command_line`enter code here` 
    utility.execute() 
    File "C:\Python34\lib\site-packages\django-1.8-py3.4.egg\django\core\managemen 
t\__init__.py", line 304, in execute 
    django.setup() 
    File "C:\Python34\lib\site-packages\django-1.8-py3.4.egg\django\__init__.py", 
line 21, in setup 
    apps.populate(settings.INSTALLED_APPS) 
    File "C:\Python34\lib\site-packages\django-1.8-py3.4.egg\django\apps\registry. 
py", line 89, in populate 
    "duplicates: %s" % app_config.label) 
django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, d 
uplicates: admin 

我使用Python 3.4得到這個錯誤在我的命令提示符。 1和使用django.get_version（）發現的Django版本1.8。我知道有關於此的stackoverflow上的答案，但我沒有發現我沒有找到最新的答案。

編輯：我忘了，包括我的settings.py

Answer 1

你有內部INSTALLED_APPS的django.contrib.admin兩個條目。這裏的固定版本：

INSTALLED_APPS = (
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'django.contrib.admin', 
)
