配置不正确：请求的设置为INSTALLED_APPS，但未配置设置-抓取工具

Question

当我尝试在Django中运行我的scraper时，出现以下错误。

当我尝试使用内置的Django模型将抓取的数据放入数据库时​​，发生了这种情况。

回溯和错误：

/usr/bin/python3.6 /home/xxxxxx/Desktop/project/teo/movierater/scrap.py
Traceback (most recent call last):
  File "/home/xxxxxx/Desktop/project/teo/movierater/scrap.py", line 7, in <module>

    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

我将其放入 bin / activate：

export DJANGO_SETTINGS_MODULE=mysite.settings

这是scraper.py的代码片段：

import django
import os
import requests
from bs4 import BeautifulSoup as bs
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from teo.movierater.api.models import *


os.environ['DJANGO_SETTINGS_MODULE'] = 'movierater.settings'
django.setup()

当我尝试在django.setup（）下面导入模型时：

import django
import os
import requests
from bs4 import BeautifulSoup as bs
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

os.environ['DJANGO_SETTINGS_MODULE'] = 'movierater.settings'
django.setup()

from teo.movierater.api.models import *

错误：

ModuleNotFoundError: No module named 'movierater'

我的项目结构和设置：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'movierater.api',
]

wsgi.py文件：

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'movierater.settings')

application = get_wsgi_application()

Answer 1

我可以在这里看到几个可能的问题。

1. 使用movierater.settings作为DJANGO_SETTINGS_MODULE的值，即export DJANGO_SETTINGS_MODULE=movierater.settings

   • 请注意，movierater的位置必须在您的PYTHONPATH（ImproperlyConfigured: You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings）上

2. 您如何启动应用，您是否尝试过python manage.py shell？

   • ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured

3. 如果要以脚本（例如python manage.py scraper）的形式启动刮板，那么最好的方法是编写自定义命令；看看use django: from "python manage.py shell" to python script
