【问题描述】：
提出不当配置（ django.core.exceptions.ImproperlyConfigured：请求的设置 INSTALLED_APPS，但未配置设置。你必须要么 定义环境变量 DJANGO_SETTINGS_MODULE 或调用 settings.configure() 在访问设置之前。
无法找出错误的原因。
下面是我的settings.py：

# Create your models here.
class Category(models.Model):

【问题讨论】：
-
您必须错误地从 settings.py 中删除了起始引号。请在 settings.py 的开头添加
"""。现在你所有的其他设置都只是作为字符串读取 -
那个已经有了，不是贴错了。但是问题仍然存在。
