文章问题描述：

关于window10，安装node.js在前端项目下打包（npm install）失败，提示找不到python的情况，安装python以后依然提示找不到python，即使你配置了环境变量也无法找了python的正确路径。

出现原因：

之前用的是window7的操作系统，以前环境没有装python，项目打包正常，后来操作系统升级windos10后出现打包失败的问题。试了网上说的通过语句设置环境变量，发现不行，试了网上说的很多方法都还是不行。

最终我出现问题的解决办法：

通过读打包报错的日志，发现上面报错日志的第22条记录。

gyp verb ensuring that file exists: C:\Python27\python.exe

于是怀疑是不是因为python的安装路径不对，所以一直报错找不到。经过重新安装python在C:\Python27\路径后，果然问题解决了。

疑问：

虽然问题解决了，但是我想python的这个路径问题一定是在哪配置的，于是我尝试在node下找了下相关的配置文件，由于手头还有其他事情最后还是放弃了，如有高手知道还请指点一下。
