This is a short writeup to help everyone get ready for the Rails 3 BugMash. The following steps and notes were taken to help you put together a new, working Rails 3 application. Many of these steps will match Yehuda Katz’s post on getting started.

It’s important to note here that Bundler doesn’t currently work if there are spaces in your path. We’ll be submitting a patch for this shortly, but for the time being, please be aware that having no spaces in your working path is a requirement to move on.

First, clone the current rails repository using git:

$ git clone git://github.com/rails/rails.git

Then, generate a new application by typing the following (from below the cloned rails directory):

$ ruby rails/railties/bin/rails new_app_name
$ cd new_app_name


Edit the new Gemfile, adding the following to the top:

directory "/path/to/rails", :glob => "{*/,}*.gemspec"
git "git://github.com/rails/arel.git"
git "git://github.com/rails/rack.git"


Double check that you change the /path/to/rails entry to point to the full path to the git clone you made of the rails repository. Then triple check that you typed it correctly. ;) Then, bundle up!

$ gem bundle
