  Step 1: Dependencies for Ruby

  edit move example delete share

  8

  Mac

  Open terminal and run the following command to install

  # install XCode or GCC to compile native gems
  xcode-select --install
  # install Homebrew from brew.sh to install libraries and dependencies
  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  # check if Homebrew is working
  brew doctor
  

  Ubuntu/Debian

  Open terminal and run the following command:

  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
  

  Windows

  In Windows, you have several options. You can decide to opt-in for a Linux conversion using cygwin, or just install Ruby on your system.

  Bare-Windows

  Nothing in particular to do. See step 2/bare windows.

  Cygwin

  Open cygwin and run the following commands

  mkdir repositories
  cd repositories
  mkdir developwithpassion
  cd developwithpassion
  git clone git://github.com/developwithpassion/devtools
  cd devtools
  

  Run the script

  ./osx_or_cygwin_kick_off
  

  And repeat the above step

  Step 2: Installing Ruby

  edit move example delete share

  7

  Mac / Linux

  For Mac / Linux, you'll want to install rvm. Type in the following commands

  sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
  gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
  curl -sSL https://get.rvm.io | bash -s stable
  source ~/.rvm/scripts/rvm
  rvm install 2.3.1
  rvm use 2.3.1 --default
  

  Windows

  RVM is unavailable on bare-windows, however you can have a look at Ruby versions managers like uru if you like. The following assume you don't use any version manager

  Installing Ruby

  The Ruby installers can be found on the [Ruby Installer website][2]. In the downloads section you will find the installers for Ruby, pick the appropiate one.

  For each version, there are two download links and the one you choose depends on your Operating System.

  Windows OS	Download
  32 Bits	Ruby 2.3.1
  64 Bits	Ruby 2.3.1(x64)

  Beware of the most recent versions, as you might run into dependency problems with gems that have not yet been adapted to run under that version of Ruby on windows. At the time of writing, some gems like bcrypt were not yet available for Ruby 2.3+

  It is always best to install Ruby in short paths, without accents, without spaces, an remember that on Windows capitalization does not matter. For example the following directory

  C:\dev\Ruby22-x64
  

  If this is your only Ruby version, you should add the executables to your PATH during the installation so you can run ruby or gems without extra steps. Otherwise you should setup the RUBY_HOME envronment variable, and add %RUBY_HOME% to your PATH variable.

  Now that you've installed Ruby, you can run the ruby -v command to make sure you have everything installed correctly

  ruby -v or rvm current
  # ruby-2.3.1
  

  Installing the DevKit

  In most cases you will also need the devkit (you can skip this section if you are sure you won't need it). After installing Ruby, download the appropriate version of the devkit and run it using

  ruby dk.rb init # Should detect your installed version of RUby, otherwise follow instructions
  ruby dk.rb install

  Step 4: Installing Rails

  edit move example delete share

  7

  Mac / Linux

  Rails ships with a lot of dependencies so it's recommended to install a JavaScript runtime like NodeJS.

  This can help speed up your production environment, because you can use CoffeeScript and the Rails Asset Pipeline. The pipeline minifies JavaScript and CSS files.

  To install NodeJS, we're going to add it using the official repository:

  curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
  sudo apt-get install -y nodejs
  

  Now we are ready to Install Rails

  gem install rails -v 4.2.6
  

  If installation was successful, the rails -v command will return the version number

  rails -v
  # Rails 4.2.6
  

  Windows

  If you use Windows, you can use this website to install the full stack, or you will need, like on Linux, to install nodejs and the rails gem.

  gem install rails
  

  Note : If you have configured your packet manager on Windows, you can also use Install-Package nodejs on PowerShell

  Step 5: Configuring Git

  edit move example delete share

  7

  We'll be using Git for our version control system so we're going to set it up to match our Github account. If you don't already have a Github account, make sure to register. It will come in handy for the future. Replace my name and email address in the following commands with the ones you used for your Github account

  git config --global color.ui true
  git config --global user.name "YOUR NAME"
  git config --global user.email "[email protected]"
  ssh-keygen -t rsa -b 4096 -C "[email protected]"
  

  The next step is to take the newly generated SSH key and add it to your Github account. You want to copy and paste the output of the following command and paste it here.

  cat ~/.ssh/id_rsa.pub
  

  Once you've done this, you can check and see if it worked:

  ssh -T [email protected]
  

  You should get a message like this

  Hi excid3! You've successfully authenticated, but GitHub does not provide shell access.

  Step 6: Setting Up MySQL

  edit move example delete share

  7

  Rails ships with sqlite3 as the default database. You are free to use a more robust database like MySQL or PostgreSQL, or a non-relational database like MongoDB.

  You can install MySQL server and client from the packages in the Ubuntu repository. As part of the installation process, you'll set the password for the root user. This information will go into your Rails app's database.yml file in the future

  sudo apt-get install mysql-server mysql-client libmysqlclient-dev
  

  Installing the libmysqlclient-dev gives you the necessary files to compile the mysql2 gem which Rails uses to connect to MySQL when you setup your Rails app

  Step 7: Setting Up PostgreSQL

  edit move example delete share

  7

  For PostgreSQL, we're going to add a new repository to easily install a recent version of Postgres.

  sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
  wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -
  sudo apt-get update
  sudo apt-get install postgresql-common
  sudo apt-get install postgresql-9.5 libpq-dev
  

  The postgres installation doesn't setup a user for you, so you'll need to follow these steps to create a user with permission to create databases. Feel free to replace 'fakhir' with your username

  sudo -u postgres createuser fakhir -s
  

  If you would like to set a password for the user, you can do the following

  sudo -u postgres psql
  postgres=# \password fakhir

  Step 8: Final Steps

  edit move example delete share

  7

  And now for the moment of truth. Let's create your first Rails application

  #### If you want to use SQLite (not recommended)
  rails new myapp
  
  #### If you want to use MySQL
  rails new myapp -d mysql
  
  #### If you want to use Postgres
  # Note that this will expect a postgres user with the same username
  # as your app, you may need to edit config/database.yml to match the
  # user you created earlier
  rails new myapp -d postgresql
  
  #### If you want to use another database (especially noSQL/MongoDB)
  rails new myapp --skip-active-record
  
  # Move into the application directory
  cd myapp
  
  # 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
  

  You can now visit http://localhost:3000 to view your new website!

  Note: If you received an error that said 'Access denied for user 'root'@'localhost' (using password: NO)' then you need to update your config/database.yml file to match the database username and password.

  Installing Rails On Ubuntu

  edit move example delete share

  0

  On a clean ubuntu, installation of Rails should be straight forward

  Upgrading ubuntu packages

  sudo apt-get update
  sudo apt-get upgrade
  

  Install Ruby and Rails dependecies

  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
  

  Installing ruby version manager. In this case the easy one is using rbenv

  git clone https://github.com/rbenv/rbenv.git ~/.rbenv
  echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
  echo 'eval "$(rbenv init -)"' >> ~/.bashrc
  

  Installing Ruby Build

  git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
  echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
  

  Restart Shell

  exec $SHELL
  

  Install ruby

  rbenv install 2.3.1
  rbenv global 2.3.1
  rbenv rehash
  

  Installing rails

  gem install rails
