2019-12-09Node.js升级报错：Node Sass could not find a binding for your current environment···

问题：

把 node 从 6.x 升级到 8.x 后，旧项目编译 scss 文件时报错：

Module build failed: Error: Missing binding D:\web\my-project\node_modules\node-sass\vendor\win32-x64-57\binding.node
Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 8.x
Found bindings for the following environments:
  - Windows 64-bit with Node.js 6.x
This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass --force` to build the binding for your current environment.

原因：

升级了node版本，sass包和现在node版本不一致，

解决方法：

重新构建 node-sass，命令如下：

npm rebuild node-sass --force

如果执行完成后不报错，就可以了。

也有可能会报 gyp Error 错误：

gyp ERR! configure error 
gyp ERR! stack Error: `gyp` failed with exit code: 1
....
gyp ERR! node -v v8.11.1 
gyp ERR! node-gyp -v v3.6.2

就需要先卸载 node-sass，然后重新安装。

npm uninstall node-sass
npm install node-sass
