django - ModuleNotFoundError：没有名为“sorl”的模块

问题描述

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

设置.py

'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

  1. Python版本：3.7.3
  2. Django 版本：3.0.10
  3. 奥斯卡版：2.1

标签： djangodjango-oscar

解决方案

有两个问题：

  1. 你需要 install sorl-thumbnail，这是一个可选的依赖项（这没有很好的记录，我会提出一个问题来解决这个问题）。

  2. 您正在阅读 Occar 2.0 版的文档，但已安装 2.1 版。这就是您收到第二个错误的原因No module named 'oscar.apps.dashboard.communication'。确保您使用与您正在使用的版本相匹配的文档版本。
