Python 如何将应用程序添加到Django CMS 3.0.12并迁移？

我是Django和DjangoCMS的新手。我最近安装了DjangoCMS，并希望按照教程和指南编写自己的应用程序

经过一些研究和测试，我发现当我尝试运行以下任一命令时：

python manage.py migrate

or

python manage.py makemigrations polls

我最终遇到以下错误：

Traceback (most recent call last):

查看堆栈，我认为这个特定错误与sekizai应用程序有关，但当我继续进行pip安装django sekizai时，我在尝试迁移时仍然会遇到相同的错误。

因此我发现了问题。DjangoCMS仅在使用Django版本1.6时才能正常工作，并且依赖于south migrations软件包/应用程序

要解决此问题，只需执行以下操作：

pip install django==1.6

另外，请确保使用了正确的教程，您可以通过查看URL来检查这一点

到目前为止，我注意到django 1.6中不存在makemigrations:（

我用django==1.9.7尝试了这个方法，如果您将django sekizai升级到0.9.0版，那么错误就会消失。 因此，只需将您的django sekizai升级到最新版本即可

pip install django-sekizai==0.9.0

---

sekizai 0.8似乎可以与包含VariableNode的Django 1.7一起使用，但Django 1.8没有。您是否使用Django 1.8？我在dekizai 0.8.1和Django 1.8上运行相同的问题，但在Django 1.7中，迁移过程是正常的（保留所有其他依赖项版本）嗨，我现在也遇到了同样的问题。这个问题与Django 1.8有关。我刚刚用

pip uninstall Django

删除了它，并用

pip install Django==1.7.7

安装了Django 1.7.7。看起来Django sekizai还不支持Django 1.8。Django==1.7可以，您不需要将Django版本降级到1.6

pip install django-sekizai==0.9.0
