未找到Laravel-Lcurd类

namespace App\Modules\CashFlowdata\Controllers;

use App\Http\Controllers\Controller; 
use App\Modules\CashFlowdata\Models\CashModel; 
use App\Modules\CashFlowdata\Lcurd\CashFlowdataLcurd;

use Auth, Womp, Graphs, Projects, Input , Permissions, LcrudForm, LcrudTable, Redirect, Session, Meta;

class CashFlowdataController extends Controller
{
    private $lcrud;
    
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct() {
        $this->middleware('auth'); 
          $this->lcrud = new CashFlowdataLcurd();
    }
}

但在这一点上我犯了错误

Class 'App\Modules\CashFlowdata\Lcurd\CashFlowdataLcurd' not found

但文件在那里,而且同名。
