我已经花了几个小时在这上面，但无法克服这个错误，它突出显示了vendorapp.blade.php文件中的“@foreach（$vendors as $vendor）”行。
登录（微风）工作正常，我可以输入用户凭据，所以我知道数据库工作正常。不知何故，尽管供应商刀片似乎不使用供应商应用控制器。当我将vendorapp.blade.php文件更改为仅显示$vendoritems时，它给出了相同的错误（未定义变量$vendoritems）。 为了还测试刀片文件是否未使用控制器，我可以在控制器中输入任何垃圾（例如“哈哈”）而不会引发错误。
路由是web.php:
<?php
use Illuminate\Support\Facades\Route;
Route::view('/', 'welcome')
->middleware(['auth', 'verified'])
->name('welcome');
require __DIR__.'/auth.php';
welcome.php 文件如下：
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<body class="antialiased font-sans">
@livewire('vendorapp')

vendorapp.php 控制器：
<?php
namespace App\Livewire;
use App\Models\VendorItem;
use App\Models\Vendor;
use Livewire\Component;
use App\Livewire\Actions\Logout;
use Livewire\WithPagination;

use WithPagination;
public $perPage = 25;
public $search = '';
public $sortDirection = 'ASC';
public $sortColumn = 'price';
public $filter = [];
public $filterInStockSydney;
public $filterInStockOther;
private $vendoritems = [];
/**

*/
public function logout(Logout $logout): void
{
$logout();
$this->redirect('/', navigate: true);
}
public function doSort($column)
{
if($this->sortColumn == $column) {
if ($this->sortDirection == "ASC") {
$this->sortDirection = "DESC";
}else{
$this->sortDirection = "ASC";
}
}else{
$this->sortColumn = $column;
$this->sortDirection = "ASC";
}
}
//lifecycle hooks
// reset the page when there is an updated perpage field
public function updatedPerPage(){
$this->resetPage();
}
// reset when there is an updated search
public function updatedSearch(){
$this->resetPage();
}
public function render()
{
$vendoritems = VendorItem::search($this->search);
if (!empty($this->filterInStockSydney)) {
$vendoritems = $vendoritems->Where('in_stock_sydney',true);
}
if (!empty($this->filterInStockOther)) {
$vendoritems = $vendoritems->Where('in_stock_other',true);
}
return view('livewire.vendorapp',
[
'vendoritems' => $vendoritems->orderBy($this->sortColumn, $this->sortDirection)
->paginate($this->perPage),
'vendors' => Vendor::orderBy('vendor','ASC')->get()
]
);
}
}
还有vendorapp.blade.php刀片文件：

我查看了班级的首都并尝试了不同的选项，但没有成功。
任何帮助都会很棒！
