Udemy Ruby On Rails Developer Course 2020 ( Free Download Tutorial) The Complete Ruby on Rails Developer Course Learns to make innovative web apps with Ruby on Rails and unleash your creativity. What you’ll learn in Udemy Ruby On Rails Developer Course 2020 ( Free Download Tutorial). Here you can get the latest Ruby distributions in your favorite flavor. The current stable version is 2.7.2. Please be sure to read Ruby’s License. I made it clear how to install it from scratch — on a clean install Mac. I have recently done a clean install of macOS Mojave 10.14.5 and installed Ruby on Rails and PostgreSQL to start web.

Setting Up A Database

Rails ships with sqlite3 as the default database. Chances are you won't want to use it because it's stored as a simple file on disk. You'll probably want something more robust like MySQL or PostgreSQL.

There is a lot of documentation on both, so you can just pick one that seems like you'll be more comfortable with.

If you're new to Ruby on Rails or databases in general, I strongly recommend setting up PostgreSQL.

If you're coming from PHP, you may already be familiar with MySQL.

MySQL

You can install MySQL server and client from Homebrew:

Once this command is finished, it gives you a couple commands to run. Follow the instructions and run them:

By default the mysql user is root with no password.

When you're finished, you can skip to the Final Steps.

PostgreSQL

You can install PostgreSQL server and client from Homebrew:

Once this command is finished, it gives you a couple commands to run. Follow the instructions and run them:

By default the postgresql user is your current OS X username with no password. For example, my OS X user is named chris so I can login to postgresql with that username.

This is an article from the RailsApps project. The RailsApps project provides Rails Example Applications that developers use as starter apps.

Install Ruby on Rails 6.0 on macOS 10.15 Catalina. Up-to-date and detailed instructions, plus troubleshooting, for the Rails newest release. How to set up and install Rails 6.0, the newest version of Rails, on macOS 10.15 Catalina.

The most complete and up-to-date installation guide for Ruby on Rails on macOS and a favorite of Rails developers. It explains how to set up a development environment for Rails, the same used by any professional Rails developer.

If You Are New to Rails

To use Rails on macOS, you'll need Ruby (an interpreter for the Ruby programming language) plus gems (software libraries) containing the Rails web application development framework. If you're new to Rails, see What is Ruby on Rails? or get the free book Learn Ruby on Rails.

Ruby Version Managers

You may hear about one-click installation programs such as RailsInstaller, Cinderella, and BitNami RubyStack. These installation programs are often outdated. Most developers install from scratch.

MacOS comes with a 'system Ruby' pre-installed. MacOS Catalina includes Ruby 2.6.3 which is not the newest version. Do not use the system Ruby (see an article for why). You should install a Ruby version manager and update to the newest Ruby version. You'll find instructions below.

Use Chruby to switch between Ruby versions. Some developers prefer RVM or rbenv but I now recommend Chruby.

A Ruby version manager makes it easy to switch between Ruby versions. I recommend Chruby. RVM was popular in the past but its additional features (its gemsets) are no longer necessary and it adds unnecessary complexity. Sam Stephenson's rbenv is also popular, but requires extra steps (the rehash command) and modifies gems when you install them.

Even if you are a student only building new Rails applications, you should be prepared to manage multiple versions of Ruby. In the future, you will need to install newer Ruby versions as they are released. And if you maintain older Rails applications, you will need a Ruby version manager.

You'll need to prepare your computer before installing Ruby on Rails.

Prepare Your Computer

A Hosted Development Alternative

You can use Ruby on Rails without actually installing it on your computer. Hosted development, using a service such as AWS Cloud9, means you get a computer 'in the cloud' that you use from your web browser. Any computer can access the hosted development environment, though you'll need a broadband connection. Cloud9 is free for small projects.

Using a hosted environment means you are no longer dependent on the physical presence of a computer that stores all your files. If your computer crashes or is stolen, you can continue to use your hosted environment from any other computer. Likewise, if you frequently work on more than one computer, a hosted environment eliminates the difficulty of maintaining duplicate development environments. However, most developers set up a local developmemt environment on their own computer.

These instructions are for macOS Catalina 10.15.

If You Updated to macOS Catalina

If you updated to Catalina from an earlier version of macOS (sometimes called an 'over the top' installation), and you previously installed a Rails development environment, your earlier installation remains intact. You will need to install the new version of Xcode Command Line Tools (full instructions below). Though Rails is still intact after an update, read through this article and take this opportunity to update your development environment.

Upgrade macOS to Catalina

MacOS Catalina was released on October 7, 2019. Make sure you have the latest version of macOS. Under the Apple menu, check 'About This Mac.' It should show 'Version 10.15.0' or newer. If you've owned your Mac for several years and haven't updated macOS, be prepared to spend several hours updating the operating system.

If you need to upgrade, see Apple's instructions Upgrade to macOS Catalina. You can install macOS 10.15 (Catalina) from the Mac App Store for free. Allow plenty of time for the download and installation (it may take several hours).

If you've already done development on earlier Mac versions, be aware of these changes in Catalina:

Catalina uses Zsh as a default shell instead of Bash. You'll set configurations (such as PATH and aliases) in the .zshrc file.
Apple has removed the /usr/include folder making it difficult to compile some older system tools.

Terminal Application (for Beginners)

To learn more about Unix shell commands, read The Command Line Crash Course or Learn Enough Command Line to Be Dangerous.

You'll need to use the Terminal application to install Ruby and develop Rails applications. The Terminal application or console gives us access to the Unix command line, or shell. We call the command line the shell because it is the outer layer of the operating system's internal mechanisms (which we call the kernel). Search for the macOS Terminal application by pressing the Command-Spacebar combination (which Apple calls 'Spotlight Search') and searching for 'Terminal.' Or look in the Applications/Utilities/ folder for the Terminal application.

You'll also need a text editor (typically VS Code or Atom) to configure your Mac (and for writing code).

Launch the Terminal application. Then try out the terminal application by entering a shell command:

$ whoami

Don't type the $ character. The $ character is a cue that you should enter a shell command. This is a longtime convention that indicates you should enter a command in the terminal application. The Unix shell command whoami returns your username.

Just a reminder to absolute beginners: Press 'Enter' after you type the command.

Is Xcode Already Installed?

You need to install Apple's Xcode Command Line Tools to get the Unix tools needed to install Ruby and develop with Rails. Xcode is Apple's software library for macOS developers. You don't need all of Xcode for Rails development. You just need the Xcode Command Line Tools. Only install the full Xcode package if you are doing development of applications for the Apple operating systems.

Check if you have previously installed the full Xcode package:

$ xcode-select -p

Scenario 1

If you see:

xcode-select: error: unable to get active developer directory...

The Xcode package is not ins
