1096 error network This is most likely not a problem with npm itself
1096 error network and is related to network connectivity.
1096 error network In most cases you are behind a proxy or have bad network settings.

1096 error network If you are behind a proxy, please make sure that the
1096 error network 'proxy' config is set properly.  See: 'npm help config'
1097 verbose exit [ 1, true ]

解决办法：

1、执行：

npm config get proxy
npm config get https-proxy

如果返回值不为null，继续执行：

npm config set proxy null
npm config set https-proxy null

2、执行：

npm config set registry http://registry.cnpmjs.org/

3、直接编辑c盘下的.npmrc文件，将registry的值修改为：

registry = http: //registry.cnpmjs.org

ps：建议直接执行第2种或第三种方法应该就可以了
