初始化项目：
cd uvTestProject
uv python pin 3.14t
uv init
会生成 .python_version 文件，内容： 3.14+freethreaded
pyproject.toml
[project]
name = "uvtestproject"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.14"
dependencies = []
运行脚本： uv run main.py
uv run main.py
Using CPython 3.14.4+freethreaded interpreter at: C:\Python314\python3.14t.exe
Creating virtual environment at: .venv
Hello from uvtestproject!
会使用制定编译器创建环境 .venv
spyder
参考： https://www.dschoni.de/programming/144/
windows系统层级安装spyder：
uv tool install spyder
warning: `~\.local\bin` is not on your PATH. To use installed tools, run `$env:PATH = "~\.local\bin;$env:PATH"` or `uv tool update-shell`.
项目层级安装Spyder kernels 到uv创建的项目 .venv 中（不会添加到项目requirements） ：
cd uvTestProject
uv pip install spyder-kernels
启动：
uvx spyder
其他
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
