Python AttributeError:type object'；皮蒙戈'；没有属性'；db'；和Mongodb在一起

我是flask和mongodb的新手，我正在尝试将我的应用程序拆分为多个部分，但是我在导入时遇到了问题，我返回了以下错误

错误在routes/users.py中 AttributeError:type对象“PyMongo”没有属性“db” 你能帮我一下吗

在users.py中解析

app.config['MONGO_URI'] = 'mongodb://localhost:27017/Users'
app.register_blueprint(users)

mongo = PyMongo(app)
