安装nodeJs插件时遇到错误

版本：es:5.6.10 , head:5.0

git clone git://github.com/mobz/elasticsearch-head.git

安装nodejs

npm install grunt-cli
npm install grunt
grunt -version 

启动

cd elasticsearch-head
grunt server

可能遇到的报错：

1. Local Npm module "grunt-contrib-clean" not found. Is it installed?
2. Local Npm module "grunt-contrib-concat" not found. Is it installed?
3.  Local Npm module "grunt-contrib-watch" not found. Is it installed?
4.  Local Npm module "grunt-contrib-connect" not found. Is it installed?
5.  Local Npm module "grunt-contrib-copy" not found. Is it installed?
6. Local Npm module "grunt-contrib-jasmine" not found. Is it installed?
Warning: Task "connect:server" not found. Use --force to continue.

运行一下命令（PS：此处需要在head的目录中运行）：

npm install grunt-contrib-clean --registry=https://registry.npm.taobao.org
npm install grunt-contrib-concat --registry=https://registry.npm.taobao.org
npm install grunt-contrib-watch --registry=https://registry.npm.taobao.org
npm install grunt-contrib-connect --registry=https://registry.npm.taobao.org
npm install grunt-contrib-copy --registry=https://registry.npm.taobao.org
np install grunt-contrib-jasmine --registry=https://registry.npm.taobao.org
