npm install时报错gyp ERR! stack Err

当你确定你做的所有操作基本符合正确但无法解决你的问题的时候，尝试换一个方向突破

环境：windows10

具体报错信息如下

gyp verb ensuring that file exists: C:\Python27\python.exe
gyp ERR! configure error

我的主要搜索目标是在python2.7找不到这个信息上，根据网上各种帖子尝试都没成功，

gyp ERR! stack Error: Can't find Python executable "python2.7", you can set the PYTHON env variable.

最后一次搜索是搜索的node-sass错误

npm ERR! node-sass@4.11.0 postinstall: `node scripts/build.js`

最终在这个贴子找到了答案，被墙了，很多时候，可能真的需要换个方向，emmm，头铁啊老铁

//windows设置变量 sass_binary_site，指向淘宝镜像地址。
set SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass/ && npm install node-sass

或者

//设置全局镜像源：
npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
