You got to add python to your PATH variable. One thing you can do is Edit your Path variable now and add
您必须将 python 添加到您的 PATH 变量中。您可以做的一件事是现在编辑您的 Path 变量并添加
;%PYTHON%;
;%PYTHON%;
Your variable PYTHON should point to the root directory of your python installation.
你的变量 PYTHON 应该指向你的 python 安装的根目录。

You are running the Command Prompt as an admin. You have only defined PYTHON for your user. You need to define it in the bottom "System variables" section.
您正在以管理员身份运行命令提示符。您只为您的用户定义了 PYTHON。您需要在底部的“系统变量”部分定义它。
Also, you should only point the variable to the folder, not directly to the executable.
此外，您应该只将变量指向文件夹，而不是直接指向可执行文件。
