I absolutely love this script and use it on my Ghost blog. Do you mind adding a header to the top with usage documentation and a license?

Unfortunately this isn't working for me for some reason. I keep getting errors like this:

npm-f3-install.sh: line 115:  8272 Killed                  npm install --verbose --only="$only" > /dev/null 2>&1

For what it is worth, I'm running it with npm-f3-install.sh production --silent (also tried with all) based on this recommendation. Anyone have any ideas?

Update: Ended up just resizing my droplet to 1GB of RAM and then resizing it after I finished the NPM install.

Epic script! 😄

I'll leave the following commands; May be help for those wishing to run this from a terminal:

curl -o npm-f3-install.sh https://gist.githubusercontent.com/SuperPaintman/851b330c08b2363aea1c870f0cc1ea5a/raw/4d3e792c6a54def095f451eeedc50d33ae361339/npm-f3-install.sh
sudo chmod +x npm-f3-install.sh
./npm-f3-install.sh
