django.core.exceptions.ImproperlyConfigured。即使我尝试了所有配置方法，我也会收到相同的错误

Question

即使我已经相应地配置了 DJANGO_SETTINGS_MODULES，我仍然收到错误消息。

错误：django.core.exceptions.ImproperlyConfigured：请求设置 INSTALLED_APPS，但未配置设置。您必须在访问设置之前定义环境变量 DJANGO_SETTINGS_MODULE 或调用 settings.configure()。 这是我的views.py：

import requests
from bs4 import BeautifulSoup
from django.shortcuts import redirect, render
from django.shortcuts import render
from django.http import HttpResponse
import os
from models import *
requests.packages.urllib3.disable_warnings()
def index(request):
    session=request.Session() 
    session.headers={"User-Agent":"Googlebot/2.1 (+http://www.google.com/bot.html)"}
    url="https://weather.com/en-IN/weather/today/l/9d531fc505eb4a93a90a7e8303ccaa22a142c9370b68391129de5019ee7adf5b"
    content=session.get(url,verify=False).content
    soup=BeautifulSoup(content,"html.parser")
    for hit in soup.findAll(attrs={'class':'today_nowcard-temp'}):
        head=hit.text
        summ=(hit.next_sibling.text)
        weather=News()
        weather.header=head
        weather.summary=summ
        print(head)
        print(summ)
        weather.save()
    return redirect("../")
def news_list(request):
    weathers=News.objects.all()
    context={
        'object_list': weathers,
    }
    return render(request,'index.html',context)

这是settings.py：
