Composer memory exhausted on shared host

Question

A previously working sandbox on a shared FreeBSD host now fails to run composer update or install with a memory exhausted error. Before yesterday I was able to run php ./composer.phar update without a problem. I do not believe that more memory is required. I can update the project on a Windows system without any issue. What variables other than memory size contribute to the memory exhausted error?

To test this I moved the contents of .../vendor and the composer.lock file to a different directory then ran php ./composer.phar install --prefer-dist. [Composer is in the project directory so that I can update it locally rather than expect the host master to keep it updated.] The above command results in:

% php ./composer.phar install --prefer-dist

Edit #2, fatal error (using composer 1.1.0) continued, as it differs from that above:

Answer 1

you can try this, I'm success

php -d memory_limit=-1 /usr/local/bin/composer/composer.phar require guzzlehttp/guzzle

this is my first answer!!!wow

Answer 2

Composer update use a lot memory to resolve dependencies

Your only option on server with so little memory is to provide composer.lock either by committing it to the repository or copy to server from continuous integration server.

There is no other way to run composer on server with 128mb ram
