Windows安装Python3.11

在Python安装包大陆镜像站下载python本体。推荐python3的稳定版 python3.11.8

双击刚刚下载的exe文件，在安装界面，不要勾选Install launcher for all uers，一定要勾选Add Python 3.x to PATH，然后点Install Now

检查：安装完成后，在系统环境变量PATH中应有如下条目

%LOCALAPPDATA%\Programs\Python\Python3x\
%LOCALAPPDATA%\Programs\Python\Python3x\Scripts\
%LOCALAPPDATA%\Programs\Python\Launcher\
