You should not use <Route component> and <Route children> in the same route; <Route children> will be ignored

　　import Home from './programme/containers/home.jsx'

<Switch>
    <Route exact path="/login" component={Login}/>
    <Route path="/home" component={Home}>
     　　<Route path="/model" component={Model}/>
        <Route path="/result" component={Result}/>
    </Route>
    <Redirect from="/" to="/home" />
</Switch>

调整为

import Home from './programme/containers/home.jsx'

<Switch>
    <Route exact path="/login" component={Login}/>
    <Home>
         <Route path="/model" component={Model}/>
         <Route path="/result" component={Result}/>
    </Home>
    <Redirect from="/" to="/home" />
</Switch>

没有足够的理论知识，没有多余的解释，暂做项目问题记录
