macOS install

Install rbenv (ruby environment)

rbenv is a ruby version manager similar to rvm however rbenv works on both Mac & Linux. If you have to learn something - it's nicer to learn something that covers two environments rather than one in case you ever need to use it in a mac/linux environment.

1. Install developer libraries from Apple

xcode-select --install

2. Install brew
3. Install rbenv (Terminal app)

brew install rbenv

4. Setup rbenv

rbenv init

5. Add rbenv to your ~/.bash_profile NOTE: these will not give you back any feedback to tell you they are complete.

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile

echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

6. Reopen the terminal and install ruby

rbenv install 2.4.1

7. Setup the version of Ruby you wish to use

rbenv local 2.4.1

8. Once Ruby has been set to local you should be able to verify which version you have

ruby -v

9. Install Ruby On Rails

gem install rails --version 5.1.1 --no-ri --no-rdoc && rbenv rehash

Type rails -v to test your version

Ubuntu Install

Install rbenv (ruby environment)

rbenv is a ruby version manager similar to rvm however rbenv works on both Mac & Linux. If you have to learn something - it's nicer to learn something that covers two environments rather than one in case you ever need to use it in a mac/linux environment.

1. Install git if you haven't already
2. Update your Ubuntu (in your terminal)

sudo apt-get update

3. Get some required dependancies

sudo apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3 libgdbm-dev nodejs sqlite3 libsqlite3-dev  

4. Using git - download rbenv git repo to a hidden directory

git clone https://github.com/rbenv/rbenv.git ~/.rbenv

5. Add terminal commands for rbenv NOTE: these will not give you back any feedback to tell you they are complete.

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc

echo 'eval "$(rbenv init -)"' >> ~/.bashrc

6. Run command for rbenv

source ~/.bashrc

7. Check if rbenv works

type rbenv

You should get back a "rbenv is a function" in the terminal

8. Install ruby-build to help rbenv using git

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

9. Install ruby using rbenv

rbenv install 2.4.1

10. Setup the version of Ruby you wish to use

rbenv local 2.4.1

11. Once Ruby has been set to local you should be able to verify which version you have

ruby -v

12. Install Ruby On Rails

gem install rails --version 5.1.1 --no-ri --no-rdoc && rbenv rehash

Type rails -v to test your version

Windows Install

1. Download and install Ruby 2.4.1-1 (x64)
2. You will be given options during the install [1,2,3]. One at a time use all 3 options.
3. Once Ruby has been installed you should be able to verify which version you have, open Powershell or cmd and type:

ruby -v

4. Install rails using Powershell/CMD

gem install rails

5. Type rails -v to test your version
