求问，windows安装babel出错

Question

gyp ERR! configure error

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

gyp ERR! stack     at failNoPython (C:\Users\Administrator\AppData\Roaming\npm\node_modules\cnpm\node

_modules\npminstall\node_modules\node-gyp\lib\configure.js:401:14)

gyp ERR! stack     at C:\Users\Administrator\AppData\Roaming\npm\node_modules\cnpm\node_modules\npmin

stall\node_modules\node-gyp\lib\configure.js:356:11

按http://www.ruanyifeng.com/blog/2016/01/babel.html里面的教程，我在文件夹内通过安装 cnpm install --save-dev babel-cli 出错了，是不是要安装python，求分析谢谢！
