django - 启动时出现 Django KeyError

问题描述

我不小心拉出了我的 Django 构建的旧 git 存储库（它在 Heroku dyno 上运行）并且它覆盖了我的整个本地构建，我设法将它恢复到以前在我的本地构建上工作的最新 git 存储库（但不是我的 Heroku dyno ）和服务器现在不会在本地运行或在我的实时构建上运行？

来自外壳的错误：

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

    del DATABASES['default']['OPTIONS']['sslmode']
KeyError: 'OPTIONS'

编辑：

del DATABASES['default']['OPTIONS']['sslmode']

是 Heroku 在 git 提交时添加的部分。删除了这个以及其他解决问题的 Heroku 更改。
