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

这个报错在以下情形会出现

第一种

<Switch>
       <Route exact path="/home/index" component={HomeIndex} />
       <Route path="/home/order" component={HomeOrder}>
          <Route path="/home/order2" component={HomeOrder2}></Route>
       </Route>
       <Route path="/home/assets" component={Assets} />
    </Switch>

Route组件下面不能嵌套Route组件，react-router4版本以上就不让这么写了

第二种（超级坑！！！）

<Switch>
       <Route exact path="/home/index" component={HomeIndex} />
       <Route path="/home/order" component={HomeOrder}>
       </Route>
       <Route path="/home/assets" component={Assets} />
    </Switch>

Route组件之间不能有空格换行！所以，要么<Route></Route>这种样子或者写成一个自闭和标签<Route />!!!
