Memory limit errors#

Composer may sometimes fail on some commands with this message:

PHP Fatal error: Allowed memory size of XXXXXX bytes exhausted <...>

In this case, the PHP memory_limit should be increased.

Note: Composer internally increases the memory_limit to 1.5G.

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. /etc/php5/cli/php.ini for Debian-like systems):

; Use -1 for unlimited or define an explicit value like 2G
memory_limit = -1
