sudo apt-get update

sudo apt-get git

sudo apt-get install curl

sudo apt-get install nodejs

RVM (Ruby Version Manager)

RVM is a tool for managing, installing and facilitating use of Ruby environments. In short, it would be something like a "version manager" for Ruby. It create isolated environments to develop in Ruby, giving the conditions to use multiple versions of Ruby and gems in a single machine in a clear and unconstrained way.

Installing RVM

To install RVM, run in the terminal:

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

\curl -sSL https://get.rvm.io | bash -s stable

Opening RVM

The RVM will be installed in your HOME directory. To open RVM, run the command line below by replacing USER with your username:

source /home/USER/.rvm/scripts/rvm

To check if the RVM was opened, type:

rvm --version

Note: If you want the RVM to start automatically when the terminal is opened, add the following line to your .bashrc:

[[ -s $HOME/.rvm/scripts/rvm ]] && source $HOME/.rvm/scripts/rvm

Installing Ruby and Ruby on Rails in the RVM:

First, enter the following command to authorize RVM to automatically install required dependencies on your system:

rvm autolibs enable

After that, use RVM to install Ruby and set the default version of Ruby to use:

rvm install ruby 2.4

rvm use 2.4 --default

Next, install Ruby on Rails using the RubyGems package manager (RubyGems is installed in conjunction with Ruby):

gem install rails -v 5.0.2

And finally, test Ruby on Rails:

rails --version
