Class“Magento\Elasticsearch7\Model\Client\ClientBuilder”not found#0

我按照这个教程在我的Windows设备上安装Magento：https://ccbill.com/kb/install-magento-windows#ftoc-heading-4
第3步是使用此命令安装Magento：php bin/magento安装：安装--base-url=”http://mystore.magento.com“--db-host=“localhost”--db-name=“magento”--db-user=“root”--db-password=“magento2”--admin-firstname=“Bruce”--admin-lastname=“Banner”--admin-email=”thehulk@store.com“--admin-user=“Hulk”--admin-password=“Hulk123”--language=“en_US”--currency=“USD”--timezone=“America/芝加哥”--use-rewrites=“1”--search-engine=“elasticsearch7”--elasticsearch-host=“localhost”--elasticsearch-port=“9200”
但安装总是失败，给我这个：

研究这个问题给了我两个选项，来运行这个命令：composer require elasticsearch/elasticsearch：~5.1
给了我一个兼容性问题，但运行这个没有错误：composer require elasticsearch/elasticsearch
我还发现有人建议我添加以下内容：使用Elastic\Elasticsearch\ClientBuilder
不知道它应该去哪里，但我试图将它添加到elasticSearch.php文件，这两个都没有解决问题。
