我可以讓Django-oscar在Python 3下工作嗎？

Question

我正在使用Python 3.6.0，Django 1.10.6和Oscar 1.4.0版final。

我見過的討論看起來相似的錯誤信息和報告解決方案的某些解決（如更新什麼是「還是」舊的時間自動生成wsg​​i.py），或之前添加import django和django.setup()幾乎接近頂部（即SECRET_KEY和INSTALLED_APPS，向上移動靠近頂部）。我發現Github上的錯誤消息更接近匹配，Raven的用戶已經明確地從他們的項目中刪除了標準用戶或身份驗證模塊。然而，我還沒有找到某個地方有人報告錯誤，除了全面清除從基於Django的不相關項目中刪除標準Django應用程序之外，還有一個解決方案。

特定的錯誤消息和跟蹤不會向我大喊什麼行是在懷疑它是由INSTALLED_APPS包含'django.contrib.contenttypes'觸發的問題。我收到的時候我嘗試運行它的軌跡是：

我目前settings.py，有益或幫倒忙從什麼據稱爲他人工作的如此修改，最多也就是一個不變import os：

from oscar.defaults import * 

from django.conf import settings 

settings.configure() 

# SECURITY WARNING: keep the secret key used in production secret! 
SECRET_KEY = '[DELETED]' 

from oscar import get_core_apps 

INSTALLED_APPS = [ 
    #'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'django.contrib.flatpages', 
    'django.contrib.sites.models.Site', 
    'django.contrib.contenttypes.models.ContentType', 
    'compressor', 
    'widget_tweaks' 
] + get_core_apps()

奧斯卡有什麼可以/應該做些什麼，它擁有應該得到的所有應用程序？

Answer 1

'django.contrib.sites.models.Site', 
'django.contrib.contenttypes.models.ContentType' 

這不應該在已安裝的應用程序部分。這些是模型，已安裝的應用程序部分主要針對應用程序。
