PythonAnyWhere SECRET_KEY設置不能為空

Question

所以我想在pythonanywhere上部署我的網站。 我創建了virtualenv，安裝了Django和網站所需的所有應用程序。 我創建了新應用，並將其與從GitHub克隆的項目連接。 這是我的Web應用程序中的設置的屏幕截圖：

我的項目結構如下：

我的settings.py

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/1.10/howto/deployment/checklist/

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.environ.get('SECRET_KEY')

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False
ADMIN_ENABLED = False

ALLOWED_HOSTS = []

還有我的/var/www/falca94_pythonanywhere_com_wsgi.py

# +++++++++++ DJANGO +++++++++++
# To use your own django app use code like this:
import os
import sys
#
## assuming your django settings file is at '/home/falca94/mysite/mysite/settings.py'
## and your manage.py is is at '/home/falca94/mysite/manage.py'
path = '/home/falca94/blog_project'
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'blog_project.settings'
os.environ['SECRET_KEY'] = 'mysecretkey'
os.environ['EMAIL_PASS'] = 'emailpassword'
os.environ['DATABASE_PASS'] = 'databasepass'

# then, for django >=1.5:
from django.core.wsgi import get_wsgi_application
from django.contrib.staticfiles.handlers import StaticFilesHandler
application = StaticFilesHandler(get_wsgi_application())
## or, for older django <=1.4
#import django.core.handlers.wsgi
#application = django.core.handlers.wsgi.WSGIHandler()

我不明白為什么會收到此錯誤：

Answer 1

您的settings.py嘗試從環境變量讀取SECRET_KEY ：

SECRET_KEY = os.environ.get('SECRET_KEY')

該錯誤表明您嘗試運行Django應用程序的環境中未設置此環境變量。
