Solution 1:

A quick solution for memory limit in Magento 2 command is directly adding memory limit inside command.

For Compilation command,

php -dmemory_limit=5G bin/magento setup:di:compile

For Deployment

php -dmemory_limit=5G bin/magento setup:static-content:deploy

You can change as per 5G to max if issue not resolve.


Solution 2:


If you are using PHP >= 5.3.0 and you used the Magento 2.1.x and above, then after you run composer install, two files will be created in your root directory and your pub directory named .user.ini

Edit those files to override your PHP.ini settings, in this case is the memory_limit

; Set PHP memory limit to 768M which already enough for compilation tasks 
memory_limit = 768M 
max_execution_time = 18000

If you are using Apache, you will need to care the files inside root directory only, not the /pubone and vice versa if you are using engineX (nginx)


Hope it helps.
