背景

把Hexo博客源码整个从32位的Linux系统搬到64位系统下，本来还没发现32位和64位，直到执行hexo clean的时候提示错误才发现。node_modules文件夹的指定模块报错。

# hexo clean
ERROR Plugin load failed: hexo-generator-amp
Error: Missing binding /blog/node_modules/node-sass/vendor/linux-x64-64/binding.node
Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 10.x

Found bindings for the following environments:
  - Linux 32-bit with Node.js 8.x

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.

错误信息

主要就是下面这两句

Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 10.x

Found bindings for the following environments:
  - Linux 32-bit with Node.js 8.x

就是node sass找不到适合你现在Linux 64位系统的环境捆绑， 当前找到的是适合32位Linux系统的。

解决方法

里面也附带了解决的办法

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.

这通常是因为你换了环境然后执行npm install导致。 执行npm rebuild node-sass 来下下载适合你的当前环境的捆绑。
