您已更新 Django 版本或数据库后端。如果您使用的是 VCS，则可以回滚到以前的工作状态并尝试重新安装库（我希望您已在 中指定了版本requirements.txt）。回溯  File "C:\Program Files (x86)\Python383-32\lib\site-packages\django\db\utils.py", line 207, in __getitem__    backend = load_backend(db['ENGINE'])  File "C:\Program Files (x86)\Python383-32\lib\site-packages\django\db\utils.py", line 111, in load_backend    return import_module('%s.base' % backend_name)  File "C:\Program Files (x86)\Python383-32\lib\importlib\__init__.py", line 127, in import_module    return _bootstrap._gcd_import(name[level:], package, level)  File "C:\Program Files (x86)\Python383-32\lib\site-packages\sql_server\pyodbc\base.py", line 12, in <module>    raise ImproperlyConfigured("Django %d.%d.%d is not supported." % VERSION[:3])
