python 多版本切换

第一步

在系统变量的Path中，添加：%WherePython% 和 %WherePython%\Scripts\ 两组值，系统根据这个寻找python内容

第二部

@echo off
%1 mshta vbscript:CreateObject("Shell.Application").ShellExecute("cmd.exe","/c %~s0 ::","","runas",1)(window.close)&&exit
choice /c 123 /m "Python37->Press 1,    Python39->Press 2,   Python310->Press 3"
if errorlevel 3 goto Python310
if errorlevel 2 goto Python39
if errorlevel 1 goto Python37
 

:Python37
setx WherePython D:\Python37 /M
goto end

:Python39
setx WherePython C:\ProgramData\Anaconda3 /M
goto end

:Python310
setx WherePython D:\Python310 /M
goto end
 
:end
echo GoodBye
