我今天安裝依賴包時一直報錯
$ npm install npm ERR!

我之前把npm的registry換成國內的淘寶鏡像的所以一開始認為報錯跟鏈接什么的沒什么關系。后來我在網上看了一下相關博客，都說換成cnpm就可以，我也嘗試了一下，果然成功了。雖然我還不是特別理解這其中的奧妙之處，但是也得到了解決問題的方法。
下面三種方法都可以
1.通過config命令
npm config set registry http://registry.cnpmjs.org npm info underscore （如果上面配置正確這個命令會有字符串response）
2.命令行指定
npm --registry http://registry.cnpmjs.org info underscore
3.編輯 ~/.npmrc 加入下面內容
registry = http://registry.cnpmjs.org
結果
