这个项目工作正常,直到我使用environ使SECRET_KEY和DEBUG作为环境变量使用environ.在我得到这个错误:-

输出为:

(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]

    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>

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值未加引号

SECRET_KEY = my_secret_key_value
DEBUG = True

在添加environ之前,项目运行良好。我得到这个错误是因为environ吗?我应该如何删除这个错误?

解决了!!
在.env文件中删除赋值运算符和var之间的空格,以及值和赋值运算符之间的空格。

SECRET_KEY=my_secret_key_value
DEBUG=True

.env文件应与settings.py位于同一目录中

0x6upsns

1.首先在设置所在的目录中创建.env文件
1.其次,删除变量和键值之间的所有空格(即KEY=my_key

import environ

env = environ.Env()
environ.Env.read_env(os.path.join(BASE_DIR, 'somepath/.env')) #<-- where ever your .env lies inside project directory
SECRET_KEY = os.environ.get('somekeyInsidenvFile',env('somekeyInsidenvFile')) #

首先,像这样安装Django-environ

pip install django-environ

接下来,像这样在www.example.com中导入环境settings.py

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')

这是一个普通的Django设置文件,你所做的就是从异常中导入os,environ,ImproprilyConfigured,编写函数get_env_variable并根据SECRET_KEY调用它
接下来,在与包含此内容的www.example.com文件相同的目录中创建一个.env文件settings.py

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

用你自己的. you can reference this material替换密钥字符串

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

清除.env中的空格!!
在.env文件中删除赋值运算符和var之间的空格,以及值和赋值运算符之间的空格。

DJANGO_SECRET_KEY="NDCNSDIWBDVIBDVUOWDVJ30F9342FE20F9JCME"
DEBUG="True"

如果您的SECRET_KEY$(美元符号)开头,您将遇到与OP相同的异常,这是一个已知的bug,带有django-environ包。
在这种情况下,只需生成新的SECRET_KEY:

from django.core.management.utils import get_random_secret_key
print(get_random_secret_key())

其实有一个简单的解决办法。
settings.py

import os
import environ

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

env = environ.Env()

# read th .env file
environ.Env.read_env(env_file=str(BASE_DIR) + '/.env')    

SECRET_KEY = env('SECRET_KEY')

DEBUG = env('DEBUG')

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

.env文件

SECRET_KEY=secret_key_value
DEBUG=True

最后,不要在.env文件中的等号前后使用空格。

也有同样的错误。我个人的问题是由于.env文件的位置。
我的文件结构如下:

BASEDIRECTORY
  Django-Project
    myapp1
    myapp2
    myInitializedProjectApp
      settings.py
      wsgi.py
      ...
  .env
  .gitignore
  Dockerfile
  ...

所以我的env应用程序和我的Django-project文件夹在同一层
在我的www.example.com中settings.py,在声明BASE_DIR之后,我包括:env.read_env('../.env')
我猜这基本上是将文件夹从BASE_DIR向上发送到它需要读取的.env的位置。
