Question

我是Django和DjangoCMS的新手。我最近安装了DjangoCMS，并希望按照教程Tutorial 1和Introduction to Plugins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其中一个命令时：

python manage.py migrate

or

python manage.py makemigrations polls

我最终遇到以下错误：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/username/folder/DjangoCMS/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 338, in execute_from_command_line

    from django.template import VariableNode, Variable
ImportError: cannot import name VariableNode

我认为它特定于我在settings.py文件中设置的已安装应用程序，因为我一直在处理此错误，我发现大多数用于DjangoCMS的INSTALLED_APPS中设置的应用程序实际上都没有＃39 ;必须安装我在本地运行网站。

INSTALLED_APPS = (
    'djangocms_admin_style',
    'djangocms_text_ckeditor',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.admin',
    'django.contrib.sites',
    'django.contrib.sitemaps',
    'django.contrib.staticfiles',
    'django.contrib.messages',
    'djangocms_style',
    'djangocms_column',
    'djangocms_file',
    'djangocms_flash',
    'djangocms_googlemap',
    'djangocms_inherit',
    'djangocms_link',
    'djangocms_picture',
    'djangocms_teaser',
    'djangocms_video',
    'cms',
    'menus',
    'sekizai',
    'reversion',
    'mptt',
    'south',
    'mywebsite',
    'polls'
)

查看堆栈我认为这个特殊错误与sekizai应用程序有关但是当我继续并且pip install django-sekizai时，我仍然在尝试迁移时遇到相同的错误。

Answer 1

所以我发现了这个问题。 DjangoCMS仅在使用Django 1.6版时才能正常工作，并且依赖于南迁移软件包/ app。

为了解决问题，请执行以下操作：

pip install django==1.6

还要确保使用正确的教程，您可以通过查看URL来查看。

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

Answer 2

我用Django == 1.9.7尝试了这个，如果你将django-sekizai升级到版本0.9.0，那么错误消失了。所以只需将你的django-sekizai升级到你的Django版本的最新版本。

pip install django-sekizai==0.9.0

如何将应用程序添加到Django CMS 3.0.12并进行迁移？
