Solve rack issue for Dreamhost and Rails 3 rc

Question

my environment.rb contains:

ENV['GEM_PATH'] = File.expand_path('~/.gems') + ':/usr/lib/ruby/gems/1.8' 

My gemfile contains:

source 'http://rubygems.org'
source :gemcutter

gem 'rails', '3.0.0.rc'


gem 'mysql'
gem 'haml'
gem 'RedCloth'
gem "friendly_id", "~> 3.0"
gem 'agnostic-will_paginate', "~> 3.0.0"


# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
#gem 'capistrano'


# To use debugger
# gem 'ruby-debug'

# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri', '1.4.1'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

The error after deploying a Rails 3 app on dreamhost is:

You have already activated rack 1.1.0, but your Gemfile requires rack 1.2.1. Consider using bundle exec.

Other notes: Rails 3 beta 4 is working.

Reverted to beta 4 version for now. Would be good to know how to fix this issue for Rails 3. Dreamhost is ok for staging apps.

Did you find a solution for this?

Answer 2

I had the same problem on my shared account on Dreamhost, I was able to do it works this way:

On my local machine:

bundle package

On Dreamhost:

bundle install --path vendor/bundle --local

And it looks work perfectly, I hope I was help you ...
