Composer Update failed — out of memory

Question

I got this error when running composer.phar update on my VM:

PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried t

Answer 1

Rather than permanently setting your memory limit to an increased number (or unlimited), I use this;

# Running an update
COMPOSER_MEMORY_LIMIT=-1 composer update

COMPOSER_MEMORY_LIMIT=-1 composer require PACKAGE/NAME

That temporarily set's the composer memory limit env variable to unlimited.
