1、下载pyenv
进入git官网，打包下载zip到本地
2、解压到安装目录
解压下载好的pyenv-win-master.zip到自己的安装目录，如D:\Program Files
3、配置环境变量
右击桌面 此电脑 --> 属性 --> 高端系统设置 --> 环境变量 --> 新建系统变量
变量名: PYENV
变量值: D:\Program Files\pyenv-win-master
- 作用：
PYENV环境变量指向pyenv-win的安装目录。- 用途：这个变量帮助系统识别
pyenv的安装路径，使得命令行可以正确调用pyenv工具。例如，如果pyenv安装在用户目录的某个位置，PYENV变量会告诉操作系统pyenv所在的路径。
变量名: PYENV_HOME
变量值: D:\PythonEnv
- 作用：
PYENV_HOME指定了pyenv存储所有 Python 版本和环境的目录。- 用途：这个环境变量告诉
pyenv要把下载和安装的 Python 版本存储在哪里。通常，PYENV_HOME与PYENV环境变量指向的位置有关，但它专门用于存储和管理 Python 版本的文件。
编辑系统变量 Path，新增两行
%PYENV%\pyenv-win\bin
%PYENV%\pyenv-win\shims
4、验证是否安装成功
C:\Users\Administrator>pyenv --version
The system cannot find the file specified.
pyenv 3.1.15、查询可安装版本
C:\Users\Administrator>pyenv install --list | findstr 3.9
3.9.0a1-win32
3.9.0a1
3.9.0a2-win32
3.9.0a2
3.9.0a3-win32
3.9.0a3
3.9.0a4-win32
3.9.0a4
3.9.0a5-win32
...# 先升级一下pyenv，我发现即使下载最新的，有可能也会找不到最新版本

* 3.13.2 (set by D:\Program Files\pyenv-win-master\pyenv-win\version)3.9.137、安装virtualenv
因为一个项目要配置一个虚拟环境，所以搭配virtualenv使用，当前在全局3.13.2版本下
C:\Users\Administrator>python -V
Python 3.13.2C:\Users\Administrator>pip list

[notice] To update, run: python.exe -m pip install --upgrade pip9、配置字virtualenv的环境变量
因为使用pyenv时会有多个python的解释器，而且安装的python并没有添加环境变量，这里需要手动添加，我们通过pyenv安装的所有的python都存放在 %PYENV%/pyenv-win\versions下
编辑环境变量 Path，添加
D:\Program Files\pyenv-win-master\pyenv-win\versions\3.13.2\Scripts
添加后安装虚拟环境env1 env2，发现可以 指定我们安装过的所有版本的虚拟环境。

修改virtualenv的虚拟环境目录
先删除安装的虚拟环境

env2C:\Users\Administrator>rmvirtualenv env1Deleted C:\Users\Administrator\Envs\env1C:\Users\Administrator>rmvirtualenv env2Deleted C:\Users\Administrator\Envs\env2配置环境变量
新建系统变量

变量值：D:\PythonEnv （自定义）
重新打开cmd，重新创建虚拟环境

依次重后往前删除已配置的环境变量、删除D:\PythonEnv、删除D:\Program Files\pyenv-win-master安装目录
