Memory error when installing sulu-minimal via Composer

[JOduMonT]

even after trying this trick

# php -dmemory_limit=-1 $HOME/bin/composer.phar create-project sulu/sulu-minimal . -n
Installing sulu/sulu-minimal (1.6.22)

mmap() failed: [12] Cannot allocate memory

Fatal error: Out of memory (allocated 779100160) (tried to allocate 75497472 bytes) in phar:///home/jodumont/bin/composer.phar/src/Composer/DependencyResolver/RuleSet.php on line 90

so what else I could try ?

Hello @JOduMonT,
is it possible that you have only 750mb ram available on your system?

[JOduMonT]

@alexander-schranz sorry I omit few detail
it's a VPS, and yes the 750mb seams a hard limit

[alexander-schranz]

@JOduMonT maybe you find some help in the composer https://github.com/composer/composer/issues.
Performance improvements can be make when you have unzip installed in your OS also make sure you have the newest version of composer by running php $HOME/bin/composer.phar self-update.

Else I would try to create the project on a machine which has more memory. Then deploy the project to your VPS with the composer.lock file which was created after the create project where you then run just composer install which should not need so much memory as it don't need to resolve the dependencies.

thank @alexander-schranz; I'll try the composer.lock alternative
