无法将“ python”识别为内部或外部命令 [英] 'python' is not recognized as an internal or external command

问题描述

所以我最近安装了Python版本2.7.5，并做了一些循环操作，但是问题是，当我转到cmd并键入 python testloop.py 我收到错误消息：

So I have recently installed Python Version 2.7.5 and I have made a little loop thing with it but the problem is, when I go to cmd and type python testloop.py I get the error:

'python'不被识别为内部或外部命令

'python' is not recognized as an internal or external command

我尝试设置路径但无济于事。

I have tried setting the path but no avail.

这是我的路径：

C：\Program Files\Python27
