Question

从https://django-oscar.readthedocs.io/en/2.0.4/internals/getting_started.html安装django-oscar时出现以下错误

settings.py

INSTALLED_APPS = [

},
}

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

我还发现未安装solr-thumbanil或solr。如果我安装solr-thumbnail，则会出现以下错误

技术细节

Python版本：3.7.3
Django版本：3.0.10
奥斯卡版本：2.1

Answer 1

有两个问题：

您需要安装sorl-thumbnail，这是一个可选的依赖项（此文档没有很好的文档说明，我将提出一个解决问题的解决方案）。
您正在阅读Ocsar的2.0版文档，但已安装2.1版。这就是为什么您遇到第二个错误No module named 'oscar.apps.dashboard.communication'的原因。确保您使用的version of the documentation与所使用的版本相匹配。

Answer 2

在settings.py的{{1}}列表中，添加INSTALLED_APPS，例如：

'communication',

如果它不起作用，请检查

INSTALLED_APPS = [

'communication',

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

您在

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

中添加的

模块必须是

INSTALLED_APPS

Answer 3

您尚未安装软件包。

尝试一下：

pip install sorl-thumbnail

ModuleNotFoundError：没有名为“ sorl”的模块
