Warning: 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. If you accidentally passed it from a parent component, remove it from the DOM element.
引起警告的原因是： 在react-router-dom的<Switch>中使用了<div>
就像这样：
<Router>
<Switch>
<div>
<Route path="/" exact component={Home} />
<Route path="/newMeetings" exact component={NewMeetings} />
<Route path="/changeMeetings" exact component={ChangeMeetings} />
<Route path="/peopleSetting" exact component={PeopleSetting} />
</div>
</Switch>
</Router>
解决办法很简单，把<div>换成<Fragment>就行了~
