兼容性问题

在 package.json 的配置中加入 browserslist

"browserslist": [
  "last 2 version",
  "> 1%"
]

postcss.config.js 中可配置

module.exports = {
  map: false, //关闭source-map
  plugins: {
    "postcss-preset-env": {
      stage: 0, //哪怕是处于草案阶段的语法，也需要转换
      preserve: false,
    },
    "postcss-apply": {},
    "postcss-color-function": {},
  },
};

.babelrc

{
    "presets": [
        ["@babel/preset-env", {
            "useBuiltIns": "usage",
            "corejs": 3
        }]
    ]
}
