看後面那麼多404想必是因為網路引起，安裝出錯，於是於是去查了一下，原來npm，也像Linux的軟體一樣有自己的鏡像源，感覺不錯，雖然也存在依賴關係，非常不錯、

下面就是切換npm鏡像源的方法有三種：

1.通過config命令

npm config set registry https://registry.npm.taobao.org  npm info underscore （如果上面配置正確這個命令會有字串response）

2.命令列指定

npm --registry https://registry.npm.taobao.org info underscore 

3.編輯~/.npmrc加入下面內容

registry = https://registry.npm.taobao.org

如果還是失敗就把三個方法都做一次
