PythonAnywhere部署DjangoVet项目时遭遇JSONDecodeError求助

部署Codecademy的DjangoVet最终模块到PythonAnywhere时，error.log中出现如下JSON解析错误：

1. dollarbi11_pythonanywhere_com_wsgi.py #

# +++++++++++ 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()

2. settings.py 第26-29行 #

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

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

3. keys.json 内容 #

{
    "SECRET_KEY" = "XXXX"
}

解决方案 #

问题出在keys.json的语法错误：JSON规范中键值对必须用冒号:分隔，而你用了等号=。修改keys.json内容如下：

{
    "SECRET_KEY": "XXXX"
}

修改后重启PythonAnywhere上的Django应用即可解决该错误。
