For resource controllers its namesinstead of name:
Naming Resource Routes
By default, all resource controller actions have a route name; however, you can override these names by passing a names array with your options:
命名资源路由
默认情况下，所有资源控制器操作都有一个路由名称；但是，您可以通过传递带有选项的名称数组来覆盖这些名称：
Route::resource('photos', 'PhotoController')->names([
'create' => 'photos.build'
]
