今天安裝mongoose一直報錯，上圖

具體的錯誤記錄：

看下面，發現是npm 的 shasum check failed，查資料發現，可能是因為NPM未更換國內淘寶鏡像所致....換一下

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.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

我選用了第一種方法，然後成功安裝。

npm install mongoose錯誤解決
