PHP Fatal error: Allowed memory size

[directonlijn]

After running: composer require mtownsend/response-xml

I get the following error:

PHP Fatal error:  Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///cygdrive/c/ProgramData/ComposerSetup/bin/composer.phar/src/Composer/DependencyResolver/Solver.php on line 220

@directonlijn You have to set your memory limit to a higher amount in your php.ini file

; Maximum amount of memory a script may consume
; http://php.net/memory-limit
memory_limit=512M // default
memory_limit=1G // 1 GB
memory_limit=-1 // unlimited
