cannot import name 'PyJWTError' from 'jwt'

这个错误通常是由于导入的 `PyJWTError` 类的名称错误导致的。

请确保您的代码中正确导入了 `PyJWTError` 类，正确的导入方式如下：

from jwt.exceptions import PyJWTError

如果您还没有安装 PyJWT 库，请使用以下命令安装：

pip install PyJWT

如果您已经安装了 PyJWT 库，但仍然遇到此错误，请尝试更新库：

pip install --upgrade PyJWT

如果问题仍然存在，请检查您的代码是否存在其他导入错误或语法错误。

cannot import name 'token_required'

This error typically occurs when you are trying to use a function or decorator called `token_required` but it cannot be found in the current scope or module.

If you are trying to use the `token_required` decorator from the Flask-RESTful library, you may need to make sure that you have imported it correctly. Here is an example of how to properly import and use `token_required` in a Flask-RESTful application:

from flask import Flask
from flask_restful import Api, Resource, reqparse
from flask_jwt_extended import jwt_required, get_jwt_identity
from your_module import token_required

app = Flask(__name__)
api = Api(app)

class SecretResource(Resource):
    @jwt_required
    @token_required
    def get(self):
        current_user = get_jwt_identity()
        return {'secret': 'Hello, {}! This is a secret message.'.format(current_user)}

api.add_resource(SecretResource, '/secret')

if __name__ == '__main__':
    app.run(debug=True)

In this example, we have imported `token_required` from `your_module` and used it as a decorator alongside `jwt_required` to protect a resource endpoint. Make sure that the `token_required` function is defined and imported correctly in your module.

python3.12.0 from jwt.jwt import JWT 报错

根据提供的引用内容，似乎是使用了Java JWT库的依赖，而不是Python的JWT库。因此，如果你想在Python中使用JWT库，需要使用Python的JWT库，而不是Java的。你可以使用以下命令安装Python的JWT库：

pip install PyJWT

然后，你可以使用以下代码导入JWT库：

import jwt
