node-sass安装的坑

set SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass/
npm install node-sass

修改.npmrc

sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
phantomjs_cdnurl=https://npm.taobao.org/mirrors/phantomjs/
electron_mirror=https://npm.taobao.org/mirrors/electron/
registry=https://registry.npm.taobao.org

npm install -g cnpm; cnpm install

如果是Nexus则set SASS_BINARY_SITE=https://nexus/repository/npm/
