node-sass 安装报错解决办法

npm install安装node-sass时出现以下问题:

Cannot download https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-46_binding.node

Hint: If github.com is not accessible in your location
try setting a proxy via HTTP_PROXY, e.g.
export HTTP_PROXY=http://example.com:1234
or configure npm proxy via
npm config set proxy http://example.com:8080'

• 直接解决：npm install node-sass
• 上面方法不行的话，原因是node-sass被墙掉了，那我们用淘宝镜像cnpm安装：

npm install -g cnpm --registry=https://registry.npm.taobao.org

cnpm install node-sass@4.5.3 --save
