React does not recognize the `computedMatch` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `computedmatch` instead

今天启动一个项目发现报如下错误：

React does not recognize the `computedMatch` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `computedmatch` instead

然后搜索了一下，是由于在react-router-dom的<Switch>中使用了<div>标签导致，只需要把div移到外层或者使用React.Fragment包裹即可。
