執行npm install報錯：npm ERR! code EINTEGRITY

　　命令行執行npm install報錯以下：

D:\frontend\viewsdev>npm install
npm ERR! code EINTEGRITY
npm ERR! sha512-8qtu6VYSXUExVPx6H8s8+OhQo0UQP7ogAoOa2bOPCvnhlpaGVYf3yh45WNa7PhhdWSOGQW3DdblqMX8UJ7Cu6g== integrity checksum failed when using sha512: wanted sha512-8qtu6VYSXUExVPx6H8s8+OhQo0UQP7ogAoOa2bOPCvnhlpaGVYf3yh45WNa7PhhdWSOGQW3DdblqMX8UJ7Cu6g== but got sha512-OvgW+e/pBS2QuX5CTDaaE+DM62t8mMk+IJfcpE3Zv1DC03DwoOKcyqRHlA+lkXWahSOPmvYZJSEDUKX0nOeLDw==. (4954746 bytes)

　　後來發現是npm版本問題，須要更新至最新版本：

D:\frontend\viewsdev>npm install -g npm
C:\Users\wulf\AppData\Roaming\npm\npx -> C:\Users\wulf\AppData\Roaming\npm\node_modules\npm\bin\npx-cli.js
C:\Users\wulf\AppData\Roaming\npm\npm -> C:\Users\wulf\AppData\Roaming\npm\node_modules\npm\bin\npm-cli.js
+ npm@6.3.0
added 396 packages in 45.85s

　　從新install成功：

D:\frontend\viewsdev>npm install
