断言错误：视图函数映射正在覆盖现有的端点函数：包装器

问题描述

如果我使用 Flask-JWT-Extended 3.25.0，一切都很好，但是当我使用最新版本时，我收到此错误

AssertionError: View function mapping is overwriting an existing endpoint function: wrapper

名为 wrapper 的函数是否与另一个函数冲突？我的应用程序中没有这样的函数/端点，我使用的其他一些包是：

• pip
• 轮子
• 烧瓶
• Flask-JWT-Extended==4.0.2
• sqlAlchemy
• Flask_sqlAlchemy
• Flask_Migrate
• alembic
• pytz
• google-api-python-client
• gevent
• pytest
• pytest-cov
• firebase 管理员
• psycopg2-二进制
• boto3

为什么？

解决方法

请务必仔细阅读 4.0.0 重大更改和升级指南：https://flask-jwt-extended.readthedocs.io/en/stable/v4_upgrade_guide/。

您可能错过了其中的某些内容，例如仍在使用 @jwt_required 而不是 @jwt_required()
