错误联系,

之前使用pycharm写的Django的时候,每当我更改玩setting的设置后,会出现错误如下,

/usr/bin/python /home/peggy/PycharmProjects/DDjango/NewRec/manage.py runserver 8000
Traceback (most recent call last):
File "/home/peggy/PycharmProjects/DDjango/NewRec/manage.py", line 10, in <module>

File "/usr/local/lib/python2.7/dist-packages/Django-1.7.3-py2.7.egg/django/apps/registry.py", line 89, in populate
"duplicates: %s" % app_config.label)
django.core.exceptions.ImproperlyConfigured: Application labels aren‘t unique, duplicates: admin

解决方法

django内部已经包含一个 admin 的应用，你新建的app和系统的重名了，换个名字就好了。
发现在INSTALLED_APPS里面有两个admin,删掉一个可以了
