Php artisan命令用32Gb的RAM运行内存

Question

I have in DigitalOcean a droplet of 32Gb ram with 12 CPU (resize for occasion)

I run php artisan command (laravel 4.2) which never ran. What could be happening?

And the error message after more than 10 minutes:

I answer my own question, with the help of @aynber and @MartinBarker

I solved the problem droping the current database, updating composer (composer update in my local and pushing composer.lock which contain the updates to the server, in the server run composer install with sudo (is not recommendable use sudo with composer.) and runing sudo php artisan.
