您的数据库django没有南数据库模块'south.db.postgresql_psycopg2'

I have a django app with version as 1.6.5, i am trying to upgrade it to 1.8, but on the way i got the below error right after the django version was increased to 1.8

我有一个版本为1.6.5的django应用程序，我正在尝试将其升级到1.8，但是在django版本增加到1.8之后我就得到了以下错误

There is no South database module 'south.db.postgresql_psycopg2' for your database. Please either choose a supported database, check for SOUTH_DATABASE_ADAPTER[S] settings, or remove South from INSTALLED_APPS.

Code

码

INSTALLED_APPS = [
   'django_messages',
    'avatar',
    'tinymce',
    'south',
    'tracking',
    ......
  ]

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'HOST': '127.0.0.1',
        'NAME': 'xxxxxx',
        'USER': 'xxxxxx',
        'PASSWORD': 'xxxxxx',
        },
    }

So what was the problem and what need to be done to fix this ?

那么问题是什么以及需要做些什么才能解决这个问题呢？

I have even tried with the below setting and receiving the same error when running the django local server

我甚至尝试使用以下设置并在运行django本地服务器时收到相同的错误

SOUTH_DATABASE_ADAPTERS = {
    'default': "south.db. postgresql_psycopg2"
}

5 个解决方案

#1

The solution i found to the above problem was just removing the south from virtual environment apart from all the changes mentioned above

我发现上述问题的解决方案只是将虚拟环境中的南方移除，而不是上面提到的所有变化

#2

You are probably still referencing to South with an import somewhere.

你可能仍然在某个地方导入南方。

Just:

只是：

pip uninstall south

Then:

然后：

python manage.py runserver

And resolve import errors.

并解决导入错误。

#3

Since Django 1.7, migrations are part of the framework. Instead of using South, you probably want to migrate to django.db.migrations.

自Django 1.7以来，迁移是框架的一部分。您可能希望迁移到django.db.migrations，而不是使用South。

Generally speaking, you should always read release notes (for 1.7 and 1.8) when doing such an update.

一般来说，在进行此类更新时，您应始终阅读发行说明（适用于1.7和1.8）。

#4

Django with version >= 1.7 use built-in migration. You don't need to use south.

版本> = 1.7的Django使用内置迁移。你不需要使用南方。

For more details about Django migration framework you can refer release note - https://docs.djangoproject.com/en/1.9/releases/1.7/#schema-migrations

#5

If you are using Django < 1.7, you should also install South >= 1.0.1 if you haven’t already. This is not listed as a dependency for the sake of users who are on Django >= 1.7 and don’t need it.

如果你使用Django <1.7，你还应该安装South> = 1.0.1（如果你还没有）。对于Django> = 1.7并且不需要它的用户，这不会被列为依赖项。
