錯誤代碼如上：

解決辦法：

刪除npmrc文件。

使用鏡像

鏡像使用方法（三種辦法任意一種都能解決問題，建議使用第三種，將配置寫死，下次用的時候配置還在）:

1.經過config命令

1 2	npm config set registry http://registry.cnpmjs.org npm info underscore （若是上面配置正確這個命令會有字符串response）

2.命令行指定

1	npm --registry http://registry.cnpmjs.org info underscore

3.編輯 ~/.npmrc 加入下面內容

1	registry = http://registry.cnpmjs.org
