启动时出现Django键错误

我不小心拉了一个Django版本的旧git repo（它在Heroku dyno上运行），它覆盖了我的整个本地版本，我设法将它恢复到最新的git repo，它以前在我的本地版本（但不是我的Heroku dyno）上工作，服务器现在不会在本地或在我的实时版本上运行

来自shell的错误：

python manage.py runserver

  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/home/johnnie/.local/lib/python3.7/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line

KeyError: 'OPTIONS'

是Heroku在git提交时添加的节。

删除了此项以及解决问题的其他Heroku更改。

正如错误所述，您在

数据库中没有名为
选项的键。
字典。我设法解决了该问题，但现在在check raise SystemCheckError中有了文件“/home/johnnie/.local/lib/python3.7/site packages/django/core/management/base.py”，第441行（msg）django.core.management.base.SystemCheckError:SystemCheckError:System check发现了一些问题：错误：？：（staticfiles.E002）STATICFILES\u DIRS设置不应包含STATIC\u ROOT设置。我想知道这些问题是否是由于Heroku对我的文件进行了一些更改而导致的，因此现在我的本地版本受到了这些更改的影响？
del DATABASES['default']['OPTIONS']['sslmode']
