Question

Is 1GB RAM enough for installing composer and laravel?

Debian 9 (1 GB RAM, 25 GB storage) Apache MariaDB PHP 7.2

Composer and Laravel installed successfully

Then, attempted to add a package with composer … ran following line in Putty composer require mobiledetect/mobiledetectlib

returned the following…

Using version ^2.8 for mobiledetect/mobiledetectlib ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev)

mmap() failed: [12] Cannot allocate memory

mmap() failed: [12] Cannot allocate memory PHP Fatal error: Out of memory (allocated 878714880) (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/Solver.php on line 223

Fatal error: Out of memory (allocated 878714880) (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/Solver.php on line 223

Checked for the mobiledetect folder in /var/www/domainname/html/projectname/vendor but no folder there

Currently have 1 GB RAM in DigitalOcean, do I need to up it to 2 GB RAM for composer to run updates properly?

I ran the command … php -r “echo ini_get(‘memory_limit’).PHP_EOL;” and -1 was returned which means unlimited

I checked the php.ini file and found… ; Maximum amount of memory a script may consume (128MB) ; http://php.net/memory-limit memory_limit = -1

I used the ‘top’ command to view that only 1 % of CPU is in use

and free -m returns total used free shared buff/cache available Mem: 996 134 800 21 60 750

I read that composer increases internal memory to 1.5 GB here https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors

Any suggestions would be appreciated.

The OS you’re using plays an integral role in memory management, one of the easy hacks to eliminate these memory errors is to add Swap memory file and SSD storage also helps in faster swaps. Refer to the tutorial below: https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-centos-7
