django.core.exceptions.ImproperlyConfigured：SECRET_KEY设置不得为空

Question

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.  """

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

                    )

try:
    from local_settings import *
except:
    pass

这里也是manage.py

#!/usr/bin/env python

import sys

if __name__ == "__main__":
    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！

就像错误说的那样，您没有SECRET_KEY定义。您需要在 settings.py中 添加一个。

如果SECRET_KEY未设置，Django将拒绝启动。

您可以在docs中阅读有关此设置的更多信息。

该SECRET_KEY可以做出点事来......但如果你想使用Django生成一个，你可以从Python壳以下：

>>> from django.utils.crypto import get_random_string
>>> chars = 'abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*(-_=+)'
>>> SECRET_KEY = get_random_string(50, chars)
>>> print SECRET_KEY

将复制SECRET_KEY到您的设置文件。
