我在Django中创建了一个新项目，并粘贴了另一个项目中的一些文件。每当我尝试运行服务器时，都会收到以下错误消息：

    Traceback (most recent call last):
      File "manage.py", line 10, in <module>
        execute_from_command_line(sys.argv)
      File "/Library/Python/2.7/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
        utility.execute()
      .
      .
      .
            File "/Library/Python/2.7/site-packages/django/conf/__init__.py", line 115, in __init__
        raise ImproperlyConfigured("The SECRET_KEY setting must not be empty.")
    django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

这是我的settings.py

""" Django settings for dbe project.  """

这里也是manage.py

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "dbe.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

有什么帮助吗？谢谢！
