also i have error

php-http/discovery contains a Composer plugin which is blocked by your allow-plugins config. You may add it to the list if you consider it safe.
You can run "composer config --no-plugins allow-plugins.php-http/discovery [true|false]" to enable it (true) or disable it explicitly and suppress this
exception (false)
See https://getcomposer.org/allow-plugins

@vahidalvandi this is no error, but an information. and the information explains you what you can do to not see the message anymore, as well as a link to the composer information on what plugins are.

the plugin would automatically install a suitable PSR-7/PSR-17/PSR-18 implementation if one is required but none explicitly selected by your application.
