React 添加装饰器依赖

• 安装依赖

  yarn add @babel/plugin-proposal-decorators

• 修改package.json文件中的babel依赖

  "babel": {
      "plugins": [
        [
          "@babel/plugin-proposal-decorators",
          {
            "legacy": true
          }
        ]
      ],
      "presets": [
        "react-app"
      ]
    }
