Question

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

输出为：

(env) E:\ecommercedj>python manage.py runserver
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

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

(env) E:\ecommercedj>

settings.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值未引用

SECRET_KEY = my_secret_key_value
DEBUG = True

在添加环境之前，该项目运行良好。我是否由于eviron而收到错误消息？我应该如何清除此错误？

Answer 1

.env 文件应与 settings.py 位于同一目录中

Answer 2

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

Answer 3

在 SECRET_KEY=my_secret_key_value 之间没有空格为我解决了这个问题！

Answer 4

首先，像这样安装Django-environ

pip install django-environ

接下来，像这样在 settings.py 中导入环境

import os
import environ
from pathlib import Path
from django.core.exceptions import ImproperlyConfigured

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent

# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/3.2/howto/deployment/checklist/

# SECURITY WARNING: keep the secret key used in production secret!
env = environ.Env()
environ.Env.read_env()


def get_env_variable(var_name):
try:
    return os.environ[var_name]
except KeyError:
    error_msg = "set the %s environment variable" % var_name
    raise ImproperlyConfigured(error_msg)


SECRET_KEY = get_env_variable('SECRET_KEY')

它是普通的Django设置文件，你所做的是从异常中导入os、environ、ImproperlyConfigured，编写函数get_env_variable并针对SECRET_KEY调用

接下来，使用此内容在与 settings.py 文件相同的目录中创建一个 .env 文件

SECRET_KEY=django-insecure-b)8xiyg09+9)e4ko!o_*%5am=5(%=-%uvo5g*618619)8xcwfa

用您自己的密钥字符串替换。 you can reference this material

Answer 5

清除 .env 中的空格！！

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：

DJANGO_SECRET_KEY="NDCNSDIWBDVIBDVUOWDVJ30F9342FE20F9JCME"
DEBUG="True"

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

输出为：

settings.py

.env文件

SECRET_KEY值未引用
