react-router4 map循环出的<Link>可以切换路由地址，但是切换不了组件

Question

<ul className="nav">     <li>         <Link to="/section1">test1</Link>     </li>     <li>         <Link to="/section2">test2</Link>     </li>     <li>         <Link to="/section3">test3</Link>     </li>     //上边直接写正常     ////////////////////////////////////////     //下边就不行，地址可以切换，组件出不来，也切换不了    {list.map((item, index) => {         return <li key={index}>            <Router>                 <Link to={`/section${index + 1}`}>{item}</Link>             </Router>             </li>         })}</ul>{this.props.children}<Switch>     <Route path="/section1" component={Section1}/>1    <Route path="/section2" component={Section2}/>2    <Route path="/section3" component={Section3}/>3</Switch>

Answer 1

{list.map((item, index) => {    return <li key={index}> 
            <Link to={`/section${index + 1}`}>{item}</Link>
        </li>
    })}

因为我嵌套了2层<Router>去掉就可以了...
