python包管理工具uv

安装

参考： https://github.com/astral-sh/uv

安装python3.13： https://www.python.org/downloads/

安装到读写速度较快的盘： C:\Python313

删除系统和用户path中的WindowsApps路径，避免命令行输入python启动windows store：

%USERPROFILE%\AppData\Local\Microsoft\WindowsApps

删除后需要重新启动windows，阿三真不是东西，改的windows越来越臭。

安装uv :

python.exe -m pip install --upgrade pip
pip install uv

使用

参考： https://docs.astral.sh/uv/guides/projects/
