    from django.contrib.sites.models import RequestSite 
ImportError: cannot import name RequestSite 

我正在Django的1.10和Python 2.7。

Answer 1

RequestSite不驻留在sites.models中。

按照该1.8 docs已自1.7

Deprecated since version 1.7:

This class used to be defined in django.contrib.sites.models. The old import location will work until Django 1.9.

弃用它可以在

django.contrib.sites.requests.RequestSite

找到假设你正在使用流行django-registration-redux，其最新版本有一个fix for this，所以如果是这种情况，你应该更新的版本。
