Question

在我的App组件中，我有：

 <Switch>                                         
         <Route exact path="/" render={() => <Redirect to="/en"/> }
        />
          <Route path="/:lang(en|sv|fr)" component={Master} />
         <Route component={PageNotFound} />
 </Switch>

如果我转到mysite.com/en，则路径成功匹配激活主组件的路由。

但是，如果我转到主域（“ /”），则url重定向到mysite.com/en，但是Master组件未激活，因此不会呈现任何内容。为什么？
