AttributeError: module 'six' has no attribute 'memoryview' occurs when configuring django database for django-mssql
我的Django是最新版本,python3.8。我想为 sql server 2008 R2 配置数据库,所以我安装了 django-mssql(aka,sqlserver_ado)。 运行服务器后,出现错误:
.........

ImportError: cannot import name 'six' from 'django.utils' (C:\Program Files\Pyth

关注此 、
我打开"C:\Program Files\Python38\lib\site-packages\sqlserver_ado\dbapi.py"并将“from django.utils import six
”更改为“import six
”,并将六个模块升级到最新版本。
这次又出现了另一个错误:

我检查了六个模块,是的,它不包含一个名为 "memoryview" 的单词。但为什么 dbapi.py 包含代码“Binary = six.memoryview
”?我在 Google.So 上搜索 "six.memoryview" 很多结果,但我无法理解。
django-mssql
软件包多年未更新,并且不能与任何当前支持的 Django 版本一起使用。当前版本的 Django 要使用的包是 django-mssql-backend
:
https://pypi.org/project/django-mssql-backend/
此包支持 Django 2.2 和 Django 3.0,这是撰写本文时当前支持的版本。
