pyenv-win管理windows上多个版本python

pyenv是一款管理多个python版本的工具，可以便捷的切换使用的python版本，但是不支持windows环境，在windows环境需要使用pyenv-win

pyenv-win安装

官方介绍的安装方式比较多，在此主要记录一下我习惯的安装方式

下载pyenv-win,可以从github上下载，也可这里下载
创建文件加.pyenv, 将下载文件解压到此目录
根据解压后的文件路径设置环境变量PYENV, PYENV_HOME and PYENV_ROOT，path，参考如图所示

PYENV, PYENV_HOME and PYENV_ROOT环境变量设置
path环境变量设置
4. 验证是否成功，在控制台中执行pyenv --version输出对应版本即表示成功
