This document provides instructions for installing Ruby on Rails on OSX. It explains that Ruby on Rails is a model-view-controller web application framework written in Ruby. It then details installing Homebrew and dependencies like rbenv and Ruby. Instructions are provided for generating a new Rails project, creating the database, and running the Rails server. The final section thanks the reader.

INTRO - WHAT’S RUBY ON RAILS
Ruby on Rails, or simply Rails, is a server side web application
framework written in RUBY under MIT Licence. Rails is a Model-
View-Controller (MVC) framework, providing default structures
for a database, a web service and web pages [Wikipedia]

3. UP AND RUNNING WITH RUBY ON RAILS
INSTALLATION (OSX)
The first thing to do is to install
Homebrew
> ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Homebrew installs the stuff you need that Apple didn’t.

4. UP AND RUNNING WITH RUBY ON RAILS
INSTALLATION (OSX)
Maybe the installation gives you some error, just like these:
Then Just type:
>rm -fr /usr/local/share/man/man1/brew.1 /usr/local/share/zsh/site-functions/_brew /usr/local/share/doc/homebrew /usr/local/
etc/bash_completion.d/brew

5. UP AND RUNNING WITH RUBY ON RAILS
INSTALLATION (OSX)
Maybe the installation gives you some error, just like these:
And re-run
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
brew link autoconf
brew install rbenv ruby-build

6. UP AND RUNNING WITH RUBY ON RAILS
INSTALLATION (OSX)
Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile
rbenv install 2.3.1
rbenv global 2.3.1
ruby -v
If mysql is needed then
brew install sqlite3

7. UP AND RUNNING WITH RUBY ON RAILS
INSTALLATION (OSX)
Next important step ...installing Rails but maybe you have an old
version of gem and the rails 4 require a new gem so you have to
gem update --system 2.0.3
brew uninstall xz
since install nokogiri without giving this command
could lead an error for a dependency issue so then
gem install nokogiri -v 1.6.8

8. UP AND RUNNING WITH RUBY ON RAILS
INSTALLATION (OSX)
gem install rails -v 4.2.6
rbenv rehash
Then finally install Rails

9. UP AND RUNNING WITH RUBY ON RAILS
INSTALLATION (OSX)
brew install mysql
gem install mysql2 -v '0.4.5'
You may need a mysql client (with the relative jam)

10. UP AND RUNNING WITH RUBY ON RAILS
CREATE A NEW RAILS PROJECT
To create a brand new project go in your favourite workspace directory and type:
rails new new_rails_app
rails new new_rails_app -d mysql
but if you need mysql support type:

If you setup MySQL or Postgres with a username/password, modify the
config/database.yml file to contain the username/password that you specified
Create the database
rake db:create
rails server
