求大佬指点，给大佬递茶。公司内网，代理已经配置好，不过我的权限可能有的网站和端口会访问不了，github能上，node.js官网能上，源用的是cnpm。

Answer 1

Create a file named .npmrc in the same directory as package.json, and then install python, preferably version 2.X

Put the following sentence in it

sass_binary_site=https://npm.taobao.org/mirrors/node-sass/

Answer 2

The prompt is that you need to install python. You can install python and try it, then set the PYTHON environment variable and reinstall it.

Answer 3

Create .npmrc in the root directory

phantomjs_cdnurl=http://cnpmjs.org/downloads
sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
registry=https://registry.npm.taobao.org

After saving, re-npm install

Answer 4

I also tried to install nodesass yesterday and it failed. Later I switched to Taobao mirror and installed it successfully
$ npm install -g cnpm --registry=https://registry.npm.taobao.org (install Taobao mirror)

$ cnpm install node-sass --save (use Taobao image to install node-sass)
