Getting Started

Check to make sure you're not running Ruby from /usr/bin $ which ruby Get version info $ ruby -v macOS ships with a system Ruby installed in /usr/bin/ruby. Don't use. Instead use rbenv (not rvm) to manage Ruby versions and gem bundles.

Install rbenv

rbenv manages different versions of Ruby on your machine.

# Install
$ brew install rbenv

# Add rbenv to bash
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
$ exec $SHELL -l

Install Ruby and gem bundler

# List all Ruby versions available for install
$ rbenv install -l

# Install Ruby
$ rbenv install 2.0.0-p247

# Check target version
$ rbenv version

# Switch global version
$ rbenv global 2.0.0-p247

# Switch local version (project-specific, usually for legacy code)
$ rbenv local 2.0.0-p247

# Install gems
$ gem install bundler

Install Rails

# Install Rails
$ gem install rails --version 4.0.0 --no-ri --no-rdoc

# Verify install
$ rails -v

To switch version of Rails used in project, change Rails number in Gemfile in root folder of application and run $ bundle install.

Database

# Install global postgresql
$ brew install postgresql

# Install Postgres adapter gem
$ gem install pg -v 0.18.4

# Add to Gemfile
gem 'pg', '~> 0.18.4'

# Resolve dependencies
$ bundle install

Production Testing

$ rake db:setup
$ rails server

Troubleshooting

# Run this before rake db:setup
$ brew services start postgresql
