es 安装head插件的问题

/usr/local/node-v9.9.0/bin/npm install 执行该命令

npm WARN deprecated [email protected]: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)

npm WARN registry Unexpected warning for https://registry.npmjs.org/: Miscellaneous Warning ECONNREFUSED: request to https://registry.npmjs.org/grunt-contrib-copy failed, reason: connect ECONNREFUSED 151.101.228.162:443
npm WARN registry Using stale package data from https://registry.npmjs.org/ due to a request error during revalidation.
以上是安装head插件的报错。 node 版本 

v9.9.0

采用网上的解决办法
/usr/local/node-v9.9.0/bin/npm install -g cnpm --registry=https://registry.npm.taobao.org

/usr/local/node-v9.9.0/bin/npm start 还是报错

/usr/local/node-v9.9.0/bin/npm config set registry https://registry.npm.taobao.org 设置淘宝的  pacakge mirror

/usr/local/node-v9.9.0/bin/npm install

此时再执行/usr/local/node-v9.9.0/bin/npm run start
一切ok
