Terminal process terminated with exit code: 127

I've just installed(and think I added the settings right from the warning...) and I'm trying to just do a hello world with py but it terminates with that 127 code error when I actually try to run it so I can't even attempt to see if it works.

该 issue 提到了 VS Code 终端和一次 Python hello-world 尝试，但没有提供文件或测试。首先重现返回退出代码 127 的终端命令，并检查相关的安装和设置。完成标准是确定缺少的命令或配置，并确认 Python hello-world 程序能够成功运行。
