TypeError:set\u cookie（）获得意外的关键字参数“samesite”（flask）

Question

我尝试运行一些flask的扩展来提供用户管理和身份验证/登录，比如flaskadmin。问题是，每当我试图运行一个简单的用户登录/注册页面的示例，然后单击login或register按钮，我总是得到以下错误：

TypeError: set_cookie() got an unexpected keyword argument 'samesite'

Python报告的完整错误日志是：

Traceback (most recent call last):
  File "/usr/lib64/python2.7/site-packages/flask/app.py", line 2309, in __call__
    return self.wsgi_app(environ, start_response)

我四处寻找，但找不到解决办法。我使用的不同组件的版本是否不匹配？我们非常感谢您的帮助。在

我升级到：

Flask>=1.0.2
Flask-Login==0.4.1
Werkzeug==0.14.1

错误就消失了。我怀疑这是一个老巫师的问题
