Step one is getting some prerequisites.

Updated for Ubuntu 18.04

sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev libpq-dev

This install a system ruby and node from Ubuntu, it might be better to use RVM and NVM instead: https://rvm.io/ and https://github.com/nvm-sh/nvm

sudo apt-get install nodejs ruby-dev ruby

Next, you are ready to install bundler and rails.

sudo gem install bundler
sudo gem install rails

Rails will install some more gems once you create your first app:

rails new blog

After that you have one working ruby version with all the gear to run the recent stable rails apps.

Not all apps are created the same. Google for rvm or rbenv and consider using those if you need multiple ruby and rails versions installed in parallel. But for now if you followed the steps above you are already set to go with Ruby on Rails!

Please, take a note, that this is not a way to install ruby on rails for production! Hardening is also not discussed here.

Thanks for reading my blog!
