python - django.core.exceptions.ImproperlyConfigured：设置 SECRET_KEY 环境变量

Question

在我使用 environ 使用 environ 将 SECRET_KEY 和 DEBUG 作为环境变量之前，该项目运行良好。在我收到此错误后：-

输出是：

(env) E:\ecommercedj>python manage.py runserver
Traceback (most recent call last):
  File "E:\ecommercedj\env\lib\site-packages\environ\environ.py", line 273, in get_value
    value = self.ENVIRON[var]
  File "c:\users\matruchhaya\appdata\local\programs\python\python38-32\lib\os.py", line 675, in __getitem__
    raise KeyError(key) from None
KeyError: 'SECRET_KEY'

During handling of the above exception, another exception occurred:

django.core.exceptions.ImproperlyConfigured: Set the SECRET_KEY environment variable

(env) E:\ecommercedj>

设置.py

import os
import environ

env = environ.Env()

# read th .env file
environ.Env.read_env()

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

SECRET_KEY = env('SECRET_KEY')

DEBUG = env('DEBUG')

ALLOWED_HOSTS = ['*']
.....

.env 文件

SECRET_KEY 值未加引号

SECRET_KEY = my_secret_key_value
DEBUG = True

在添加环境之前，该项目运行良好。我是否因为 eviron 而收到错误消息？我应该如何消除这个错误？

解决了！！

在 .env 文件中，删除赋值运算符和 var 之间以及值和赋值运算符之间的空格。喜欢：

SECRET_KEY=my_secret_key_value
DEBUG=True
