<p>成功显示版本号则安装成功</p>
<h2 id="3配置npm在安装全局模块和缓存cache的路径">3、配置npm在安装全局模块和缓存cache的路径</h2>
<p>在Node.js的安装目录下新建两个文件夹，node_global和node_cache。</p>

<p>然后在命令行执行下面两个命令，注意把路径换成你们自己的路径</p>
<pre><code class="language-shell">npm config set prefix "G:\Program Files\nodejs\node_global"
npm config set cache "G:\Program Files\nodejs\node_cache"
</code></pre>

<p>执行成功后，在系统变量中新建一个变量名为 “NODE_PATH”， 值为“G:\Program Files\nodejs\node_modules” (注意换成自己的路径)</p>
