Question

我在django 1.7

中运行python manage.py syncdb时遇到错误

我使用的是Python2.7，但我在Python 3.4.3中得到完全相同的错误

$ python manage.py syncdb

Answer 1

我可以看到你正在使用django-CMS，我遇到了同样的问题。我可以假设Django的新版本可能存在问题。

根本原因是还没有创建Django表，但是cms尝试引用它们（特别是从Sites框架获取当前站点）

这不是以前版本的Django中的问题，因为你通常会python manage.py sycndb（至少在Django 1.9中删除）并且该命令创建了所有django表。

所以要解决这个问题 - 您需要在settings.py中注释掉与django CMS相关的所有内容，运行python manage.py migrate以迁移Django表，然后取消注释cms内容并再次迁移，然后它就不应该不再是一个问题了。（有时它也有助于评论当前项目来自已安装的应用程序以及cms内容，以便Django 1.9检查不会检查你的urls.py，其中包含与cms相关的条目）。

如果您在Django＆lt; 1.9但是＆gt;上遇到同样的问题1.7首先尝试执行syncdb。

希望对遇到类似问题的人有所帮助。

Answer 2

如果它不存在，请将以下内容添加到settings.py中的INSTALLED_APPS属性中：

distance = e^x

并在settings.py中添加'django.contrib.sites'。

在Django 1.7+中，进行数据库更改的首选方法是使用迁移管理命令：

SITE_ID = 1

这应该可以解决你的问题。

django.db.utils.OperationalError：没有这样的表：django_site
