运行django本地服务器时出错：`__init __（）得到了一个意外的关键字参数＆＃39; tcp_nodelay＆＃39;`

Question

一切都很好，总是没有问题。现在，当我从浏览器加载应用程序时，我收到错误。似乎没有与代码相关的东西，因为我跳过最旧的分支，我得到了同样的错误。这是我的python和django版本

$ python --version
Python 3.6.0
$ python -c "import django; print(django.VERSION)"
(1, 11, 5, 'final', 0)

这是我尝试加载127.0.0.1:8000网址时的错误

Traceback:

Exception Type: TypeError at /
Exception Value: __init__() got an unexpected keyword argument 'tcp_nodelay'

任何建议在哪里寻找解决这个令人讨厌的问题？谢谢

我遇到了相同的错误，在我的情况下，这是与settings.py文件中的缓存设置有关的问题，请检查缓存设置的选项键中是否可能有类似的内容

CACHES = {
'default': {
    'BACKEND': '-----',
    'TIMEOUT': 30000,
    'KEY_PREFIX': CACHE_MIDDLEWARE_KEY_PREFIX,
    'OPTIONS': {'ketama': True, 'tcp_nodelay': True}

我删除了选项，对我有用
