我們經常會遇到node版本過低致使不兼容當前的npm而產生報錯，如圖：
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
解決方法：建議去官網下載 https://nodejs.org/en/下載最新版本的 nodejs（如下載nodejs v8.10.0版本： https://nodejs.org/dist/v8.10.0/node-v8.10.0-x64.msi），下載完成後將其安裝到之前nodejs安裝目錄即可。
