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 3.1.1

5、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
C:\Users\Administrator>pyenv update

实际使用中会发现无法安装，因为下载不下来，使用国内源下载包之后放入D:\Program Files\pyenv-win-master\pyenv-win\install_cache目录下，重新执行安装语句就可以了。

C:\Users\Administrator>pyenv install 3.13.2

:: [Installing] ::  3.9.13 ...
:: [Info] :: completed! 3.9.13

6、查看已安装版本，设置全局版本

C:\Users\Administrator>pyenv versions3.13.23.9.13C:\Users\Administrator>pyenv global 3.13.2C:\Users\Administrator>pyenv versions
* 3.13.2 (set by D:\Program Files\pyenv-win-master\pyenv-win\version)3.9.13

7、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
Package Version
------- -------

8、安装virtualenvwrapper-win

C:\Users\Administrator>pip install virtualenvwrapper-win

9、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。

C:\Users\Administrator\Envs> mkvirtualenv env1
created virtual environment CPython3.13.2.final.0-64 in 1071mscreator CPython3Windows(dest=C:\Users\Administrator\Envs\env1, clear=False, no_vcs_ignore=False, global=False)seeder FromAppData(download=False, pip=bundle, via=copy, app_data_dir=C:\Users\Administrator\AppData\Local\pypa\virtualenv)added seed packages: pip==25.0.1activators BashActivator,BatchActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivatorC:\Users\Administrator\Envs>mkvirtualenv -p "D:\Program Files\pyenv-win-master\pyenv-win\versions\3.9.13\python.exe" env2
created virtual environment CPython3.9.13.final.0-64 in 2053mscreator CPython3Windows(dest=C:\Users\Administrator\Envs\env2, clear=False, no_vcs_ignore=False, global=False)seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=C:\Users\Administrator\AppData\Local\pypa\virtualenv)added seed packages: pip==24.2, setuptools==72.0.0, wheel==0.43.0activators BashActivator,BatchActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator

但是默认情况下，虚拟环境是安装到C:\Users\Administrator\Envs（用户目录下的）

修改virtualenv的虚拟环境目录

先删除安装的虚拟环境

C:\Users\Administrator>workonPass a name to activate one of the following virtualenvs:
==============================================================================
env1
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

变量名：WORKON_HOME

变量值：D:\PythonEnv （自定义）

重新打开cmd，重新创建虚拟环境

D:\PythonEnv>mkvirtualenv env1
created virtual environment CPython3.13.2.final.0-64 in 623mscreator CPython3Windows(dest=D:\PythonEnv\env1, clear=False, no_vcs_ignore=False, global=False)seeder FromAppData(download=False, pip=bundle, via=copy, app_data_dir=C:\Users\Administrator\AppData\Local\pypa\virtualenv)added seed packages: pip==25.0.1activators BashActivator,BatchActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivatorD:\PythonEnv>mkvirtualenv -p "D:\Program Files\pyenv-win-master\pyenv-win\versions\3.9.13\python.exe" env2
