How to install Ruby on Rails on macOS Sierra 10.12

  1. Install Homebrew. Homebrew simplifies the installation of software on Apple’s macOS operating system. Open Terminal and run the following command:
    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  2. Install Xcode. Xcode is a software package to help you develop iOS and OS X applications. You don’t need the full Xcode package to get the Command Line Tools. Check if the full Xcode package is already installed:
    xcode-select -p

    if you see:

    /Applications/Xcode.app/Contents/Developer

    it means the full package is already installed. If you don’t have it, type this command to install:

    xcode-select --install

    then will appear this :

    xcode-select: note: install requested for command line developer tools.

    An update popup window will appear to install the command line developer tools. You can choose to confirm by clicking “install”. Wait for the Command Line Tools package download to complete.

     

  3. Install Ruby. Run the following commands in your Terminal:
    brew install rbenv ruby-build
    rbenv install 2.4.1
    rbenv global 2.4.1
    ruby -v

    #ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin15]

     

  4. Install Rails
    gem install rails -v 5.0.1

    installingrailinstallingrail2

  5. Execute the Rails with this command:
    rbenv rehash
  6. Verify Rails version:

    #Rails 5.0.1

  7. Setting up a database using mySQL

    To have launchd start mysql now and restart at login:
    brew services start mysql
    Or, if you don’t want/need a background service you can just run:
    mysql.server start

  8. Final steps to create your first Rails application:
    rails new myfirstapp
    rails new myfirstapp -d mysql
    #move to the folder directory
    cd myfirstapp
    #Create the database
