To get the current memory_limit value, run: php -r "echo ini_get('memory_limit').PHP_EOL;" Try increasing the limit in your php.ini file (ex. C:\xampp\php\php.ini for Windows-like systems): ; Use -1 for unlimited or define an explicit value like 2G memory_limit = -1 Or, you can increase the limit with a command-line argument: php -d memory_limit=-1 composer.phar require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle
