Solve rack problem 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' 

Error deploying Rails 3 application on Dreamhost:

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

Other notes: Rails 3 beta 4 works.

Reverted to the beta version at the moment. It would be nice to know how to fix this problem for Rails 3. Dreamhost is approved for hosting applications.

Answer 1

I had the same problem with my shared Dreamhost account that I was able to do it like this:

On my local machine:

 bundle package 

In Dreamhost:

 bundle install --path vendor/bundle --local 

And it works great.
