Before we can start to build your Rails project, you normally need to have the followings available:

Database -- which is used to store Rails project's objects.

For example, PostgreSQL

NodeJS -- a JavaScript runtime

$ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
$ sudo apt-get install  nodejs

$ nodejs -v

v6.11.3

Bundler -- which is used to manage project's version control.

$ gem install bundler

Successfully installed bundler-1.15.4
Parsing documentation for bundler-1.15.4
Done installing documentation for bundler after 6 seconds
1 gem installed

$ bundler -v
Bundler version 1.15.4

With Ruby available, the RubyGems packaging system should be included. You can check by:
$ gem -v 2.6.8

Then you can install Rails (which is a gem) by:
$ gem install rails

Later on, you can update your Rails by:
$ gem update rails

If the installation process goes well, you should be able to run the version checking:
$ rails -v Rails 5.1.4
