为什么在Lumen项目中找不到类'Illuminate \ Http \ Resources \ Json \ JsonResource'，如何在Lumen项目中添加JSON资源？

use Illuminate\Http\Resources\Json\ResourceCollection;

works and can be retrieved inside a Lumen project. But, using

use Illuminate\Http\Resources\Json\JsonResource;

will return

Class 'Illuminate\Http\Resources\Json\JsonResource' not found`

So, how can I add JsonResource inside a Lumen project?

i think you can check your autoload_classmap.php in vendor/composer folder otherwise you simply use this use Illuminate\Http\Resources\Json\JsonResource;
