I got a problem, I tried to install a new package to my Laravel 4 project.
But when I run php composer.phar update I get this:
Loading composer repositories with package information
Updating dependencies (including require-dev)
Killed
I have looked for the problem in the Internet and saw that the memory is the problem, I think I don't have enough RAM available, I've checked this I have about 411mb free. Does composer really need more RAM?
The "Killed" message usually means your process consumed too much memory, so you may simply need to add more memory to your system if possible. At the time of writing this answer, I've had to increase my virtual machine's memory to at least 768MB in order to get composer update to work in some situations.
However, if you're doing this on a live server, you shouldn't be using composer update at all. What you should instead do is:
composer update in a local environment (such as directly on your physical laptop/desktop, or a docker container/VM running on your laptop/desktop) where memory limitations shouldn't be as severe.git push the composer.lock file.composer install on the live server.composer install will then read from the .lock file, fetching the exact same versions every time rather than finding the latest versions of every package. This makes your app less likely to break, and composer uses less memory.

Alternatively, you can upload the entire vendor directory to the server, bypassing the need to run composer install at all, but then you should run composer dump-autoload --optimize.
If like me, you are using some micro VM lacking of memory, creating a swap file does the trick:
#Check free memory before
free -m
mkdir -p /var/_swap_
cd /var/_swap_
#Here, 2G ~ 2GB of swap memory. Feel free to add MORE
sudo fallocate -l 2G swapfile
chmod 600 swapfile
mkswap swapfile
swapon swapfile
#Automatically mount this swap partition at startup
echo "/var/_swap_/swapfile none swap sw 0 0" >> /etc/fstab
#Check free memory after
free -m
As several comments pointed out, don't forget to add sudo if you don't work as root.
btw, feel free to select another location/filename/size for the file./var is probably not the best place, but I don't know which place would be, and rarely care since tiny servers are mostly used for testing purposes.
Unfortuantely composer requires a lot of RAM & processing power. Here are a few things that I did, which combined, made the process bearable. This was on my cloud playpen env.
service mysql stop (kill your DB/mem-hog services to free some RAM - don't forget to start it again!) top to watch memory/swap consumption until process is complete.composer.phar update --prefer-dist -vvv (verbose output [still hangs at some points when working] and use distro zip files). Maybe try a --dry-run too? DigitalOcean fix that does not require extra memory - activating swap, here is an example for 1gb:
in terminal run below
/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
sudo /sbin/swapon /var/swap.1
The above solution will work until the next reboot, after that the swap would have to be reactivated. To persist it between the reboots add the swap file to fstab:
sudo nano /etc/fstab
open the above file add add below line to the file
/var/swap.1 swap swap sw 0 0
now restart the server. Composer require works fine.
Here's how I succeeded in installing maatwebsite\excel package from composer in Laravel Framework:
composer update from local command prompt (then wait until all the install process finished).composer install on remote server (then wait until all process finished).If you're using docker you can use COMPOSER_PROCESS_TIMEOUT
environment:
COMPOSER_MEMORY_LIMIT: -1
COMPOSER_PROCESS_TIMEOUT: 2000 #seconds
