python——python manage.py runserver执行错误
启动服务器时:python manage.py runserver
错误信息:
Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Application labels aren’t unique, duplicates: admin
注:错误提示和c/c++不一样，最后一条记录是最准确的。如上黑体加粗部分。
解决思路:项目目录下settings.py 文件，注释掉其中重复的django.contrib.admin即可。
