Executing composer throws Killed solution

The following tutorial column of composer will introduce to you the solution to the Killed problem when executing composer. I hope it will be helpful to friends in need!

1. The error is reported as follows

root@test2:/work/usrc$ composer require qcloud/cos-sdk-v5
./composer.json has been updated
The "extra.asset-installer-paths" option is deprecated, use the "config.fxp-asset.installer-paths" option
Loading composer repositories with package information
Updating dependencies (including require-dev)
Killed

2. Solution

This reason is mostly caused by insufficient cache. It can be increased in the Linux environment. Caching is resolved.

free -m
mkdir -p /var/_swap_
cd /var/_swap_
dd if=/dev/zero of=swapfile bs=1M count=2000
mkswap swapfile
swapon swapfile
echo “/var/_swap_/swapfile none swap sw 0 0” >> /etc/fstab
free -m
