@chongshengdz I released elastic-transport-php v8.0.0-rc4 and elasticsearch-php v8.0.0-rc2. In order to install these RC versions you need to install elastic-transport-php and after elasticsearch-php as follows:

composer require elastic/transport:8.0.0-rc4
composer require elasticsearch/elasticsearch:8.0.0-rc2

This will produce the following composer.json:

"require": {
    "elastic/transport": "8.0.0-rc4",
    "elasticsearch/elasticsearch": "8.0.0-rc2"
}

Regarding the error message The client noticed that the server is not Elasticsearch and we do not support this unknown product this means you are using a previous 7.x version of Elasticsearch server or a not supported product. Starting from version 8 the elasticsearch-php client supports only Elasticsearch 8+ server.

composer require elasticsearch/elasticsearch:8.0.0-rc2

I did follow your above instruction. but the error still persist. PHP Fatal error: Uncaught Error: Class "Composer\InstalledVersions" not found in /vendor/elastic/transport/src/Transport.php:439 I am using elasticsearch version 8.1.0 elasticsearch-php v8.0.0-rc2 elastic-transport-php v8.0.0-rc4 php 8.0+

$this->client = \Elastic\Elasticsearch\ClientBuilder::create()->setHosts($host)->build(); is it correct?

Composer version 1.10.22 2021-04-27 13:10:45 centos 7

[chongshengdz]

it works fine after upgrading to Composer 2.0+. the problem is due to i was using an old version of 1.0+. "Composer\InstalledVersions" is only available on Composer 2.0+.
