Rails 2.3.5 + bundler 0.9.x

This is the best way I’ve seen so far to get Rails 2.3.5 working with Bundler 0.9.x:

Create config/preinitializer.rb with the following code:

begin

  # Require the preresolved locked set of gems.

  require File.expand_path('../../.bundle/environment', __FILE__)

rescue LoadError => e

  raise RuntimeError, "Please run `bundle lock` and try again."

  # Fallback on doing the resolve at runtime.

  require "rubygems"

  require "bundler"

  Bundler.setup

end

Update config/boot.rb and add the following before Rails.boot!

class Rails::Boot

  def run

    load_initializer

    extend_environment

    Rails::Initializer.run(:set_load_path)

end

  def extend_environment

    Rails::Initializer.class_eval do

      old_load = instance_method(:load_environment)

      define_method(:load_environment) do

        Bundler.require :default, Rails.env

        old_load.bind(self).call

end

end

end

end

Now, just run bundle install and bundle lock and you’re good to go.
