nodejs npm国内镜像

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

<code style="padding:0px; font-family:Monaco,Menlo,Consolas,'Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px; line-height:16px"><span class="pln" style="color:#000000;">npm config </span><span class="kwd" style="color:#0088;">set</span><span class="pln" style="color:#000000;"> registry http</span><span class="pun" style="color:#66660;">:</span><span class="com" style="color:#8800;">//registry.cnpmjs.org </span><span class="pln" style="color:#000000;">
npm info underscore </span><span class="pun" style="color:#66660;">（如果上面配置正确这个命令会有字符串</span><span class="pln" style="color:#000000;">response</span><span class="pun" style="color:#66660;">）</span></code>

2.命令行指定

<code style="padding:0px; font-family:Monaco,Menlo,Consolas,'Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px; line-height:16px"><span class="pln" style="color:#000000;">npm </span><span class="pun" style="color:#66660;">--</span><span class="pln" style="color:#000000;">registry http</span><span class="pun" style="color:#66660;">:</span><span class="com" style="color:#8800;">//registry.cnpmjs.org info underscore </span></code>

3.编辑 ~/.npmrc 加入下面内容

<code style="padding:0px; font-family:Monaco,Menlo,Consolas,'Courier New',monospace; font-size:12px; color:inherit; background-color:transparent; border:0px; line-height:16px"><span class="pln" style="color:#000000;">registry </span><span class="pun" style="color:#66660;">=</span><span class="pln" style="color:#000000;"> http</span><span class="pun" style="color:#66660;">:</span><span class="com" style="color:#8800;">//registry.cnpmjs.org</span></code>
