• 1參考antd-design-mobile官方與create-react-app按需引用是有問題的。
• 2原因create-react-app 最新版并不支持這么配置。
• 3解決方法 在上述配置的基礎上
  npm customize-cra react-app-rewired --save
  這兩個是按需加載的
  npm customize-cra react-app-rewired less less-loader --save
  這兩個是自定義主題色用less

修改package.json

  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
//改成
  "scripts": {
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test --env=jsdom",
    "eject": "react-scripts eject",
    "client": "serve build"
  },

• 4然后在根目錄中新建config-overrides.js

//config-overrides.js
const {
    override,
    fixBabelImports,
    addLessLoader,
  } = require("customize-cra");
  
  
  module.exports = override(
    
    addLessLoader({
      javascriptEnabled: true,
      modifyVars: { "@brand-primary": "#1cae82", "@brand-primary-tap": "#1DA57A", "@hd": "1px"},
    //   strictMath: true,
    //   noIeCompat: true,
    //   localIdentName: '[local]--[hash:base64:5]'
    }),
    fixBabelImports("import", {
        libraryName: "antd-mobile", libraryDirectory: "es", style: true // change importing css to less
      })
  )
