Django-oscar错误 - django.core.exceptions.ImproperlyConfigured：应用程序标签不是唯一的，重复：staticfiles

时间：2015-11-21 10:19:35

标签： python django ubuntu django-oscar

我正在尝试启动Django-oscar并遵循给定here的说明，但是当我尝试使用python manage.py runserver或python manage.py migrate时，我收到以下错误。我不明白这是什么，因为我是Python和Django的新手。有人可以解决这个问题吗？ 我使用的是Ubuntu，Python 2.7和Django 1.8。

2 个答案:

答案 0 :(得分：3)

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
>   'django.contrib.staticfiles',
>   'django.contrib.staticfiles',
    'django.contrib.flatpages',

您的INSTALLED_APPS包含django.contrib.staticfiles两次。您应该删除副本。

答案 1 :(得分：0)

我遇到了同样的问题，然后就这样更改了settings.py：

React.Component

有效。

顺便说一句，我正在使用python3.5和Django 2.0.9以及oscar 1.5和mysql 5.7。
