Support for the experimental syntax 'decorators-legacy' isn't currently enabled

react项目中自己写了一个装饰器，运行的时候发现报错

这是因为我们么有装支持装饰器的组件

Support for the experimental syntax 'decorators-legacy' isn't currently enabled

然后 npm run eject

在package.json文件下找到bebel属性

增加下面配置

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

项目重启
