MOBX 遇到的问题

一、Support for the experimental syntax ‘decorators-legacy’ isn’t currently enabled

用到了es7的装饰器功能，按照官网的方法不好用，后经查找使用了两个插件，方法如下：

1、npm install --save-dev customize-cra react-app-rewired @babel/plugin-proposal-decorators

2、根目录新建config-overrides.js

在文件中加入如下语句：

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

    module.exports = override(

    addDecoratorsLegacy()

);

3、修改package.json文件

"scripts": {

    "start": "react-app-rewired start",

    "build": "react-app-rewired build",

    "test": "react-app-rewired test",

    "eject": "react-app-rewired eject"

  },

4、重启服务器
