Error: Missing binding C:win32-x64-51_binding.node
Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 10.x
Found bindings for the following environments:

This usually happens because your environment has changed since running `npm install`.

缺啥補啥，上面提示的是C盤缺少C:win32-x64-51_binding.node文件，那么我們就去下載 https://github.com/sass/node-sass/releases/tag/v4.7.2一個相應的文件放到C盤，再重新npm run dev運行一下就好了。
我的是這樣解決的！
