我已经安装并安装了 Flask_security 包并发送电子邮件 我想按照在我的笔记本电脑上运行 pgadmin4 服务器模式的过程
他们要求 运行以下命令创建配置数据库： python setup.py
有人可以帮助我吗？
这是版本 4.0.0rc2
上的旧删除发布 2021 年 1 月 18 日
作为 Flask-Security 初始化一部分的 send_mail_task 和 send_mail 方法已被删除并替换为新的 MailUtil 类。实用方法 send_mail() 仍然可以使用。
如果您的应用程序没有使用任何已弃用的方法，那么唯一需要的更改是将 Flask-Mail 添加到您的包要求中（因为 Flask-Security 不再列出它）。请参阅电子邮件以获取更新的示例。
https://flask-security-too.readthedocs.io/en/stable/changelog.html#id24
那么，
from flask_security import send_mail
将会生成
ImportError: cannot import name 'send_mail' from 'flask_security'
