解决Dreamhost和Rails 3 rc的机架问题

Question

我的environment.rb包含:

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

我的gemfile包含:

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'

在dreamhost上部署Rails 3应用程序后出现的错误是:

您已经激活了机架1.1.0,但您的Gemfile需要机架1.2.1.考虑使用bundle exec.

18  config.ru

其他说明:Rails 3 beta 4正在运行.

现在恢复到beta 4版本.很高兴知道如何解决Rails 3的这个问题.Dreamhost可以用于暂存应用程序.

我在Dreamhost上的共享帐户上遇到了同样的问题,我能够这样做:

在我的本地机器上:

bundle package

在Dreamhost上:

bundle install --path vendor/bundle --local

而且效果很好.
