我正在尝试Codecademy的DjangoVet final模块，当我尝试通过PythonAnywhere部署时，在error.log中收到以下错误

下面是dollarbi11_pythonanywhere_com_wsgi.py文件的代码，该文件是我从项目教程中复制的

# +++++++++++ DJANGO +++++++++++
import os
import sys
#
## assuming your django settings file is at '/home/yourname/mysite/mysite/settings.py'
## and your manage.py is is at '/home/yourname/mysite/manage.py'
path = '/home/DollarBi11/djangovet'
if path not in sys.path:
    sys.path.append(path)
#
os.environ['DJANGO_SETTINGS_MODULE'] = 'djangovet.settings'
#
## then:
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

www.example.com的第26至29行settings.py

KEYSDIR = str(BASE_DIR)+"/keys.json"

with open(KEYSDIR) as k:
    project_keys = json.loads(k.read())

keys.json

{
    "SECRET_KEY" = "XXXX"
}
