Symfony 4控制台命令无法读取env变量

I have a small console command where I'd like to read some environment variables, but it does not seem to read the vars from the .env file or the server configs in the console (php file works)

The code

protected function execute(InputInterface $input, OutputInterface $output)
{
    $io = new SymfonyStyle($input, $output);
    $debug = $input->getArgument('debug') === 'y' ? true : false;
    $this->project = $input->getArgument('project');

    $start = new DateTime();

    $debug ? $io->text('<fg=green>Starting upload</>') : null;
    dump(getenv('APP_ENV'));
    dump(getenv('MAILER_USERNAME'));
    die;
    ...
}

Commands to test

php bin/console app:make-backup

Output:

Starting upload
false
false

php bin/console app:make-backup --env=prod

Output:

Starting upload
"prod"
false

php bin/console app:make-backup --env=dev

Output:

Starting upload
"dev"
false

.env File

APP_ENV=dev
MAILER_USERNAME=info@xxx.com

I don't see where I am doing wrong? Issue exists on nginx and apache server, BUT using getenv('MAILER_USERNAME') in any php-file works.

    I think your best bet would be to go ahead and inject the env variables. Trying to access them directly can be a bit tricky.

    # config/services.yaml
    services:
        App\Command\MyCommand:
            $appEnv:         '%env(APP_ENV)%'
            $mailerUsername: '%env(MAILER_USERNAME)%'
    
    # src\Command\MyCommand
    class MyCommand extends Command {
        protected static $defaultName = 'app:mine';
    
        private $appEnv;
        private $mailerUsername;
    
        public function __construct($appEnv,$mailerUsername) {
            parent::__construct();
            $this->appEnv = $appEnv;
            $this->mailerUsername = $mailerUsername;
        }
        protected function execute(InputInterface $input, OutputInterface $output) {
            $output->writeln(("My Command " . $this->appEnv . " " . $this->mailerUsername));
        }
    }
