I am relatively inexperienced with Composer. I am attempting to migrate from the EOL Swiftmailer package to using Symfony/mailer using directions from https://doeken.org/blog/using-symfony-mailer-without-framework
None of the related questions on SO seem to be same issue.
Server is Debian 10 (buster); PHP 8.1.7 (cli) built: Jun 25 2022; Composer 1.8.4.
composer init -n --name symfony-mailer-test succeeds in my new test directory though deprecation warnings are thrown. composer.json is created with the namespace set.
{ "name": "symfony-mailer-test", "require": {} }
Then issuing composer require symfony/mailer install dies with

composer.json is updated before it dies to
"name": "symfony-mailer-test",
"require": {
"symfony/mailer": "^6.1"
}
}
composer -V also produces errors now:

This is such a basic operation that I do not know how to begin debugging it. What should my next step be?
CodePudding user response：
You can try composer self-update.
Current Composer version 2.3.8 2022-07-01 12:10:47.
CodePudding user response：
Probably you have memory limit for the CLI config, try
php -d "memory_limit=-1" $(which composer) require symfony/mailer
To avoid warnings of the composer -V update it to the latest version.
