我在新安装South（http://south.aeracode.org/）后立即在一个全新的django项目上运行./manage.py schemamigration junk_app --initial，我收到以下错误：

Unknown command: 'schemamigration'
Type 'manage.py help' for usage.

编辑：我有版本.7（南/ init.py 有版本 =“。07”）

Answer 1

您可能没有将“south”添加到settings.py文件的INSTALLED_APPS列表中。

以下是http://south.aeracode.org/docs/installation.html#installation-configure

的引用

现在您已经在系统范围内安装了South，您需要进行配置   Django使用它。这样做很简单;只需编辑您的settings.py和   将'south'添加到INSTALLED_APPS的末尾。

如果Django似乎没有接受这个，请检查你是不是   在别处重写INSTALLED_APPS，并且可以向南运行import   从./manage.py shell里面没有错误。

添加South后，您需要运行./manage.py syncdb才能生成   南迁移跟踪表（南不使用迁移   由于各种原因，它自己的模型。

Answer 2

您可能正在使用一些旧的南版本，0.6.x甚至0.5.x.如果您键入“./manage.py help”，则应在可用命令列表中看到startmigration（iirc）。

Answer 3

使用easy_install或pip安装South，而不是使用Ubuntu软件包。这将确保您拥有最新版本。

Answer 4

我认为这个问题可能非常难以捉摸。我花了相当长的时间，然后我发现我已经覆盖了INSTALLED_APPS进行一些测试。卫生署！所以这是关键。请务必在south的末尾添加INSTALLED_APPS，如果您覆盖它，请检查一下。

Answer 5

检查您使用的settings.py文件：

./manage.py shell
import settings
settings.__file__

你可以在manage.py中看到，Django使用的设置文件是defaul：

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app.settings")

或者您可以使用：

 $./manage.py schemamigration junk_app --settings=settings --initial

而不是：

 $./manage.py schemamigration junk_app --initial

Answer 6

如果您在设置文件夹中进行了设置，请确保在路径中使用。而非 / 。示例：./manage.py schemamigration secretballot --initial --settings=settings.jacob

django south fresh install - ＆gt;错误：未知命令'schemamigration'
