我是docker容器的新手，我一直在努力从Django应用程序连接到mssql数据库，并为我的休息API成功启动docker容器。请耐心等待我长篇大论的问题。
这是我的码头工人文件

在 docker 镜像构建命令成功后。当我尝试运行映像时，出现以下错误。

我不确定如何从这里开始。我无法理解我哪里做错了。我想构建一个能够连接到服务器上存在的 MSSQL DB 的映像。我正在使用 docker 工具箱在我的本地窗口机器上运行默认的 docker 机器。从我的本地系统，我使用 Windows 身份验证连接到数据库。
如果您仔细查看错误，则没有迹象表明应用程序无法与 MSSQL 或与数据库连接相关的任何内容进行连接。
File "/usr/local/lib/python3.7/dist-packages/sql_server/pyodbc/base.py", line 7
except ImportError, e:
^
SyntaxError: invalid syntax
代码中存在语法错误。
还会建议使用高山基础 Docker 映像或官方 python 映像，因此几乎不会努力维护应用程序的依赖项。
你可以看看这里和这里。
你的 Django 版本太旧了
Django 1.5 支持 Python 2.6.5 及更高版本。
如果你在Linux下，想要检查你正在使用的Python版本，请从命令行运行python -V。
如果你想检查 Django 版本，打开一个 Python 控制台并键入
导入姜戈 姜戈。版本 (2， 0， 0， 'final'， 0(
我相信您可能尚未安装软件包django-mssql-backend。
pip install django-mssql-backend
这应该会有所帮助。
