While installing packages via npm, it failed with just the message “Killed”. Automatically this triggers me to believe it is memory related. I was after all running the VM with only 1G memory.

Fix npm install Killed

So to resolve this, you need to create and extend a swap file.

You can do this in Ubuntu 14.04 and 16.04 with the following commands:

sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon --show
sudo cp /etc/fstab /etc/fstab.bak
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
sudo sysctl vm.swappiness=10
echo 'vm.swappiness=10' | sudo tee -a /etc/sysctl.conf
sudo sysctl vm.vfs_cache_pressure=50
echo 'vm.vfs_cache_pressure=50' | sudo tee -a /etc/sysctl.conf

As always, I hope this helps anyone else with the same issue!
