Flask一个蓝图的名字发生了碰撞

Question

我遇到了一个问题。控制台说发生了蓝图名称冲突，但我认为这不属于烧瓶bootsrap问题。我相信我有一些配置或未知的东西，它让我遇到了问题。在

Traceback (most recent call last):

7770>.  Both share the same name "bootstrap".  Blueprints that are created on the fly need unique names.

这是我的密码。我不知道发生了什么。在

或者任何人都可以告诉我如何在app中查找blueprint对象并让我跟踪bug。谢谢。在

看起来你的应用程序注册了两次引导蓝图。引导程序的源代码中有一行代码将其注册到init_app()

尝试将其从此处删除：

    ...
    bootstrap,
    db,
    ma,  # Warning: Flask-SQLAlchemy must be initialized before Flask-Marshmallow.
    login_manager,

或者从这个元组：
