安装npm i react-scripts-rewired 和 customize-cra -D;
根目录新建config-overrides.js
内容如下，addDecoratorsLegacy 为react添加装饰器模式。需要再次安装 @babel/plugin-proposal-decorators

const { override, addDecoratorsLegacy } = require('customize-cra');
module.exports = override(
    addDecoratorsLegacy()
);

最后修改package.json中的react的script启动配置

"scripts": {
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",
    "eject": "react-scripts eject"
}
