node-sass安装失败解决

老项目安装node-sass@4.14.1一直失败

"node-sass": "^4.14.1",

报错环境变量Path 中没有 python2.7

gyp verb check python checking for Python executable "python2.7" in the PATH

安装python2.7,然后设置npm config set python C:\Python27

安装node-sass还是报错，看网上说用cnpm装node-sass,试了下安装node-sass 成功了

我的node版本是16.14.0，node-sass@4.14最高只支持14，换到14版本的node，又报错了

Module build failed: Error: Missing binding F:\electricity-tools\node_modules\node-sass\vendor\win32-x64-83\binding.node
Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 14.x

Found bindings for the following environments:
  - Windows 64-bit with Unsupported runtime (93)

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to download the binding for your current environment.

根据提示npm rebuild node-sass ,执行一下这个命令，最后项目终于跑起来了

话说这node-sass是真恶心，就没几次顺利安装成功过

还是用less好，哪有这么多麻烦事
