这种问题是如何解决的

@miaoxiannv
您当前使用的是Python 3.12版本，而本项目仅针对Python
3.11进行过测试。建议您参考此指南，其中提供了最
新可运行的版本（具备完整的API支持），包含预编译的二进制.whl文件及自行编译安装的详细说明。另外，本人从未使用
conda或poetry，当前uv已成为最佳选择，其功能已基本取代传统的pip工具。You are using python 3.12 - I've only tried with python 3.11
I would suggest you look at this guide which provides the newest working version with full API support including prebuilt binary .whl files as well as how to install it yourself. Also I never use
condanorpoetry,uvis the best tool for the job these days and basically has replacedpip.@ErvinXie commented on GitHub (Dec 11, 2025):
