Vue-cli 配置開發環境讓測試服務器監聽所有IP

//config/inex.js

// Various Dev Server settings
host: '0.0.0.0', // can be overwritten by process.env.HOST
port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
autoOpenBrowser: false,
errorOverlay: true,
notifyOnErrors: true,
poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-

將 host 屬性從 localhost 改為 0.0.0.0

則啟動服務器后，從相同網段可以訪問，解決了手機和電腦同時測試的問題。
