解决办法：

1. 先清除掉以前的代理设置

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

也可以先通过以下代码查看代理设置，如果返回null那就不需要清理。

npm config get proxy
npm config get https-proxy

2. 重新设置

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

或者安装一下cnpm
npm install -g cnpm –registry=https://registry.npm.taobao.org

其他
npm设置代理

设置代理
npm config set proxy=http://127.0.0.1:8087
npm config set registry=http://registry.npmjs.org

关于https
经过上面设置使用了http开头的源，因此不需要设https_proxy了，否则还要增加一句:

npm config set https-proxy http://server:port

代理用户名和密码
npm config set proxy http://username:password@server:port
npm confit set https-proxy http://username:password@server:port
