Django manage.py syncdb错误

Question

Hi I am very new to Django and I have been keep getting this error in my command prompt when typing in "manage.py 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()

    django.setup()

    "duplicates: %s" % app_config.label)

uplicates: admin

I am using python 3.4.1 and Django version 1.8 found by using django.get_version(). I know there are answers on stackoverflow about this, but I none of them that I have found are not up to date.

Edit: I forgot to include my settings.py

Answer 1

You have two entries of django.contrib.admin inside INSTALLED_APPS . Here's the fixed version:

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