Ruby Debugger

The Ruby debugger is a separate gem which requires installation, usually through your Gemfile. Note that the debugger relies on native extensions, so you need to have the Ruby headers and compilation tools setup on your system.

Ruby 1.8.7

Add the dependency to your development gems in the Gemfile:

1
2
3

group :development do
  gem 'ruby-debug'
end

Or install it from the terminal with gem install ruby-debug

Ruby 1.9.X

Assuming you’re using Bundler, add the dependency to your development gems in the Gemfile:

1
2
3

group :development do
  gem 'debugger'
end

Or install it from the terminal with gem install debugger

If you leave off the 19 you would instead get the package for use with 1.8.7 and it is incompatible with 1.9.

Redis

Ubuntu

There are a few options to install Redis on Ubuntu. The first and easiest is to use apt:

$

sudo apt-get install redis-server

This will set up redis-server to startup with the OS, but it may be a slightly dated version.

To get the latest stable version you can download from http://redis.io/download and install using their directions.

MacOS

Presuming you have Homebrew installed, you can install the Redis recipe:

$

brew install redis

Windows

There is no official Redis server version for Windows. There is a third-party port of the original service which can be used for development but may not offer 100% compatibility:

GhostScript

OS X

Use homebrew and install it with brew install ghostscript.

Linux

Install it with apt-get install ps2pdf. If you get an error that ps2pdf package can not be found, try typing ps2pdf to see if it is already installed as part of the OS.

Windows

Download and run the installer from http://www.ghostscript.com/download/gsdnld.html
