npm 安装yeoman时出现npm WARN deprecated npmconf@2.1.2报错…解决办法

我是nodeJS 小白，在用npm命令安装yeoman是，给出了这样的错误提示：

$ npm install -g yo grunt-cli bower

安装其他package是没问题的；
google 了一下好像说是npm本身因素导致的，解决办法是在执行安装yeoman命令之前先执行

npm i -g yeoman-doctor

命令，就不报错了，如图：

如果没能解决你的问题可以参考：https://github.com/yeoman/yo/issues/403
或者到npm社区寻求解决办法；
