Php 在Laravel中未找到弹性类

我在Laravel项目中安装弹性搜索时遇到问题。我犯了一个错误

未找到类“Elastica\Client”

当我尝试使用VisualStudio选项导入类时，会收到“找不到类”通知。我通过composer安装了elasticsearch，方法是添加

composer.json

文件elasticsearch，然后输入

composer update

，然后在

app/config.php

文件中添加classed并运行

composer dump autoload

。当我在测试页面上进入我的站点时，我得到了那个错误。还要提到的是，我使用了最新版本的

laravel

、

php

和

mysql

。感谢您的帮助。这是我的密码

CategoryController.php

<?php
namespace App\Http\Controllers;

use App\User;
use App\Category;
use App\Property;
use Illuminate\Http\Request;
use Elasticsearch\ClientBuilder;
use Elastica\Client as ElasticaClient;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Cookie;

class CategoryController extends Controller
{
    protected $elasticSearch;
    protected $elastica;

    public function __construct()
    {
        $this->elasticSearch = ClientBuilder::create()->build();

        $elasticaConfig = [
            'host' => 'localhost',
            'port' => 9200,
            'index' => 'pets'
        ];

        $this->elastica = new ElasticaClient($elasticaConfig);
        // Here is error!!!
    }

    public function elasticSearchTest()
    {
        dump($this->elasticSearch);
        echo "\n\nRetrieve a document:\n";
        $params = [
            'index' => 'real-estate-laravel',
            'type' => 'properties',
            'id' => '1'
        ];

        $response = $this->elasticSearch->get($params);
        dump($response);
    }
}

'providers' => [
    Elasticquent\ElasticquentServiceProvider::class,
],

'aliases' => [
    'Es' => Elasticquent\ElasticquentElasticsearchFacade::class,

尝试安装

composer

而不是

composer update

，因为

composer update

会更新整个应用程序的依赖项的较新版本。@techguru就是这么做的。相同的错误导航到您的供应商路径，并检查包是否存在或存在not@AshrafHefny它们存在你用的是哪种型号的橡皮筋？
