我们经常会遇到node版本过低致使不兼容当前的npm而产生报错，如图：
ERROR: npm is known not to run on Node.js v4.4.3
Node.js 4 is supported but the specific version you're running has
a bug known to break npm. Please update to at least ${rel.min} to use this
version of npm. You can find the latest release of Node.js at https://nodejs.org
解决方法：建议去官网下载 https://nodejs.org/en/下载最新版本的 nodejs（如下载nodejs v8.10.0版本： https://nodejs.org/dist/v8.10.0/node-v8.10.0-x64.msi），下载完成后将其安装到之前nodejs安装目录即可。
