How to Fix 'Allowed memory size of 1610612736 bytes exhausted' Error in Composer Require?

Composer Require Fails with Memory Exhaustion Error: "Allowed memory size of 1610612736 bytes exhausted"

To resolve the memory exhaustion error encountered while running "composer require hwi/oauth-bundle", investigate the following solutions:

1. Increase the PHP Memory Limit:

   • Check the current memory limit using "php -r "echo ini_get('memory_limit').PHP_EOL;"".
   • Modify the "memory_limit" value in "/etc/php5/cli/php.ini" (for Debian-like systems) to "-1" for unlimited memory or set an explicit value such as "2G".

2. Override Memory Limit with Command-Line Argument:

   • Include "-d memory_limit=-1" in the composer command: "php -d memory_limit=-1 composer.phar require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle".

3. Check PHP.ini Location:

   • Execute "php --ini" to determine the locations of loaded php.ini files.

4. Temporary Solution:

   • Use the "COMPOSER_MEMORY_LIMIT=-1 composer require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle" command.

5. Simplified Solution:

   • Run "COMPOSER_MEMORY_LIMIT=-1 composer require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle" to override the memory limit.
