PythonAnyWhere SECRET_KEY 设置不能为空

Question

所以我想在 pythonanywhere 上部署我的网站。我创建了 virtualenv，安装了 Django 和我的网站所需的所有应用程序。我创建了新应用程序并将其与我从 GitHub 克隆的项目连接起来。这是我的网络应用程序中设置的屏幕截图:

我的项目结构是这样的:

我的设置.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__)))

# 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!

还有我的/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()

我不明白为什么会出现此错误:

Answer 1

您的 settings.py 尝试从环境变量中读取 SECRET_KEY:

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

错误表明您尝试运行 Django 应用程序的环境中未设置此环境变量。

就 Python Anywhere 而言，您可以在其文档中阅读有关此案例的信息:https://help.pythonanywhere.com/pages/environment-variables-for-web-apps
