对pydantic2.x的支持

[hanasa2023]

看了下依赖要求为pydantic<2，能否提供对pyd2.x的支持

[Perseus037]

pydantic>2是可以正常使用的，没用到验证器应该没影响。

BaseSettings在V2中被移动了…… 而且我看现有代码中似乎没有用到config？

[Perseus037]

是的，你把config.py里的导入语句改为from pydantic_settings import BaseSettings试试，应该就能确保BaseSettings正确导入了

[hanasa2023]

嗯，但是我认为不应该是用户来修改

[SaltyFishFly]

pip install pydantic_settings并修改import后出现如下错误：

开了一个pr，maintainer可以稍微看一下？为了不破坏当前的依赖关系所以没有改pyproject.toml
