NPM 设置代理

**一、简介**

NPM 是Node的模块挂利器。

答案是 npm 模块仓库提供了一个查询服务，叫做 registry 。以 npmjs.org 为例，它的查询服务网址是 [https://registry.npmjs.org/][https_registry.npmjs.org] 。

这个网址后面跟上模块名，就会得到一个 JSON 对象，里面是该模块所有版本的信息。比如，访问 [https://registry.npmjs.org/react][https_registry.npmjs.org_react]，就会看到 react 模块所有版本的信息。

它跟下面命令的效果是一样的。

>     $ npm view react
>     
>     # npm view 的别名 $ npm info react
>     $ npm show react
>     $ npm v react

registry 网址的模块名后面，还可以跟上版本号或者标签，用来查询某个具体版本的信息。比如， 访问 https://registry.npmjs.org/react/v0.14.6 ，就可以看到 React 的 0.14.6 版。

**二、为访问速度等，手动修改代理为淘宝NPM镜像。**

官网地址：[https://npm.taobao.org/][https_npm.taobao.org]

### 1.临时使用 ###

npm --registry https://registry.npm.taobao.org install express
     
      
       1

### 2.持久使用 ###

npm config set registry https://registry.npm.taobao.org
     
      
       1

*  配置后可通过下面方式来验证是否成功   
    `npm config get registry`
 *  或   
    `npm info express`

### 3.通过cnpm使用 ###

npm install -g cnpm --registry=https://registry.npm.taobao.org
     
      
       1

*  使用   
    `cnpm install express`

**三、使用代理3**

镜像使用方法（三种办法任意一种都能解决问题，建议使用第三种，将配置写死，下次用的时候配置还在）:

1.通过config命令

<table style="border-collapse:collapse; border-spacing:0px; max-width:100%; background-color:transparent; margin:0px; padding:0px; border:0px; font-size:14px"> 
 <tbody style="margin:0px; padding:0px; border:0px"> 
  <tr style="margin:0px; padding:0px; border:0px"> 
   <td style="margin:0px; padding:0px; border:0px; font-size:14px"> 
    <div style="margin:0px; padding:0px; border:0px">
      1 
    </div> 
    <div style="margin:0px; padding:0px; border:0px">
      2 
    </div> </td> 
   <td style="margin:0px; padding:0px; border:0px; font-size:14px"> 
    <div style="margin:0px; padding:0px; width:1190px; border:0px"> 
     <div style="margin:0px; padding:0px; border:0px"> 
      <code style="font-family:Monaco,Menlo,Consolas,&quot;Courier New&quot;,monospace; font-size:12.6px; padding:0px; color:rgb(199,37,78); white-space:nowrap; background-color:rgb(249,242,244); margin:0px; border:0px">npm&nbsp;config&nbsp;set&nbsp;registry&nbsp;http:</code> 
      <code style="font-family:Monaco,Menlo,Consolas,&quot;Courier New&quot;,monospace; font-size:12.6px; padding:0px; color:rgb(199,37,78); white-space:nowrap; background-color:rgb(249,242,244); margin:0px; border:0px">//registry.cnpmjs.org</code> 
     </div> 
     <div style="margin:0px; padding:0px; border:0px"> 
      <code style="font-family:Monaco,Menlo,Consolas,&quot;Courier New&quot;,monospace; font-size:12.6px; padding:0px; color:rgb(199,37,78); white-space:nowrap; background-color:rgb(249,242,244); margin:0px; border:0px">npm&nbsp;info&nbsp;underscore&nbsp;（如果上面配置正确这个命令会有字符串response）</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

2.命令行指定

<table style="border-collapse:collapse; border-spacing:0px; max-width:100%; background-color:transparent; margin:0px; padding:0px; border:0px; font-size:14px"> 
 <tbody style="margin:0px; padding:0px; border:0px"> 
  <tr style="margin:0px; padding:0px; border:0px"> 
   <td style="margin:0px; padding:0px; border:0px; font-size:14px"> 
    <div style="margin:0px; padding:0px; border:0px">
      1 
    </div> </td> 
   <td style="margin:0px; padding:0px; border:0px; font-size:14px"> 
    <div style="margin:0px; padding:0px; width:1190px; border:0px"> 
     <div style="margin:0px; padding:0px; border:0px"> 
      <code style="font-family:Monaco,Menlo,Consolas,&quot;Courier New&quot;,monospace; font-size:12.6px; padding:0px; color:rgb(199,37,78); white-space:nowrap; background-color:rgb(249,242,244); margin:0px; border:0px">npm&nbsp;--registry&nbsp;http:</code> 
      <code style="font-family:Monaco,Menlo,Consolas,&quot;Courier New&quot;,monospace; font-size:12.6px; padding:0px; color:rgb(199,37,78); white-space:nowrap; background-color:rgb(249,242,244); margin:0px; border:0px">//registry.cnpmjs.org&nbsp;info&nbsp;underscore</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

3.编辑 `~/.npmrc` 加入下面内容

<table style="border-collapse:collapse; border-spacing:0px; max-width:100%; background-color:transparent; margin:0px; padding:0px; border:0px; font-size:14px"> 
 <tbody style="margin:0px; padding:0px; border:0px"> 
  <tr style="margin:0px; padding:0px; border:0px"> 
   <td style="margin:0px; padding:0px; border:0px; font-size:14px"> 
    <div style="margin:0px; padding:0px; border:0px">
      1 
    </div> </td> 
   <td style="margin:0px; padding:0px; border:0px; font-size:14px"> 
    <div style="margin:0px; padding:0px; width:1190px; border:0px"> 
     <div style="margin:0px; padding:0px; border:0px"> 
      <code style="font-family:Monaco,Menlo,Consolas,&quot;Courier New&quot;,monospace; font-size:12.6px; padding:0px; color:rgb(199,37,78); white-space:nowrap; background-color:rgb(249,242,244); margin:0px; border:0px">registry&nbsp;=&nbsp;http:</code> 
      <code style="font-family:Monaco,Menlo,Consolas,&quot;Courier New&quot;,monospace; font-size:12.6px; padding:0px; color:rgb(199,37,78); white-space:nowrap; background-color:rgb(249,242,244); margin:0px; border:0px">//registry.cnpmjs.org</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>
