Vue学习问题（一）——Run `npm rebuild node-sass` to download the binding for your current environ问题

当使用npm运行Vue项目时候出现问题Run `npm rebuild node-sass` to download the binding for your current environ时，

 

Node Sass could not find a binding for your current environment: OS X 64-bit with Node.js 6.x

Found bindings for the following environments:
- OS X 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.

然后 照着提示 运行 npm rebuild node-sass --force 也没有起作用 但是可以看的出

 

可以看的出 是因为下载不了  

这个时候 不知道为啥下载不了 

换了淘宝镜像 又试了一下 可以了

cnpm install node-sass 

不行的 可以试试 我的亲测可以的
