python - 无法从 powershell 访问 python

问题描述

当我尝试从 Windows 机器上的 powershell 命令提示符访问已安装的 python 时，出现以下错误。

我从从门户下载的 .exe 文件安装了 python，并且在安装时我在启动时检查了环境变量设置选项。

python安装在我的系统上的“C:\Users\username\AppData\Local\Programs\Python\Python38-32”这个位置

任何人都可以帮助我哪里出错了。

错误：当我从系统文件夹中输入 python

PS C:\WINDOWS\system32> python
