lack of memory and not having swap configured

I just started working with Forge + Envoyer + DigitalOcian. I'm getting this error on envoyer while I'm trying to deploy one of my old Larave 4.2 projects.

Using global Composer installation.
Loading composer repositories with package information
Installing dependencies (including require-dev)
  - Installing symfony/translation (v2.5.12)
    Loading from cache
The following exception is caused by a lack of memory and not having swap configured
Check https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors for details

                                                     
  [ErrorException]                                   
  proc_open(): fork failed - Cannot allocate memory

How can I fix this ..?

Create a swapfile in your VPS.

$ sudo fallocate -l 4G /swapfile
$ sudo chmod 600 /swapfile
$ sudo mkswap /swapfile
$ sudo swapon /swapfile

// Mount the swapfile by default
$ sudo nano /etc/fstab
// Add this line the the bottom
/swapfile   none    swap    sw    0   0

We use this handy Forge recipe:

if [ -f /swapfile ]; then
 echo "Swap file already exists."
else
 sudo fallocate -l 1G /swapfile
  sudo chmod 600 /swapfile
  sudo mkswap /swapfile
  sudo swapon /swapfile
  echo "/swapfile none swap sw 0 0" >> /etc/fstab
  echo "vm.swappiness=30" >> /etc/sysctl.conf
  echo "vm.vfs_cache_pressure=50" >> /etc/sysctl.conf
  echo "Swap created and added to /etc/fstab for boot up."
fi

Works a treat.
