我在安装 django-oscar 时遇到以下错误 https://django-oscar.readthedocs.io/en/2.0.4/internals/getting_started.html

设置.py

INSTALLED_APPS = [

'ENGINE': 'haystack.backends.simple_backend.SimpleEngine',
'URL': 'http://127.0.0.1:8983/solr',

},
}

运行 py .\manage.py migrate 或 py .\manage.py makemigrations 后，出现以下错误

我还发现 solr-thumbanil 或 solr 未安装。如果我安装 solr-thumbnail 然后我收到以下错误

您尚未安装软件包。

试试这个：

pip install sorl-thumbnail

有两个问题：

  1. 您需要安装

    sorl-thumbnail
    ，这是一个可选的依赖项（这没有很好的记录，我将提交一个问题来解决这个问题）。

  2. 您正在阅读 Ocsar 2.0 版本的文档，但已经安装了 2.1 版本。这就是您收到第二个错误

    No module named 'oscar.apps.dashboard.communication'
    的原因。确保您使用的文档版本与您正在使用的版本相匹配。

在 

settings.py
中，在您的 
INSTALLED_APPS
列表中添加 
'communication',
，例如：

INSTALLED_APPS = [

'communication',

'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
...

如果不起作用，请检查是否

'`oscar.apps.dashboard.communications'` #plural

您在 

INSTALLED_APPS
添加的模块必须是

`oscar.apps.dashboard.communication'` #singular
