请帮我解决这个问题。感谢!!!!!!

您的错误追溯清楚地表明您的SECRET_KEY为空

提高ImproperlyConfigured（＆＃34; SECRET_KEY设置不得为。空＆＃34） django.core.exceptions.ImproperlyConfigured：SECRET_KEY设置不能为空。

生成一个新的，你可以使用这个

"""
Pseudo-random django secret key generator.
- Does print SECRET key to terminal which can be seen as unsafe.
"""
from __future__ import print_function
import string
import random


# Get ascii Characters numbers and punctuation (minus quote characters as they could terminate string).
chars = ''.join([string.ascii_letters, string.digits, string.punctuation]).replace('\'', '').replace('"', '').replace('\\', '')

SECRET_KEY = ''.join([random.SystemRandom().choice(chars) for i in range(50)])

print(SECRET_KEY)

将其保存在secret_key.py文件中，并执行python secret_key.py，它会为您生成新的SECRET KEY，然后只需在您内部复制新的SECRET_KEY即可settings.py 1}}文件。

无法运行manage.py runserver
