I am attempting to deploy a RoR app using Passenger onto my DreamHost hosting

  • 0

I am attempting to deploy a RoR app using Passenger onto my DreamHost hosting account, but am having trouble getting it up and running.

My application requires two custom gems ‘amazon-ecs’ and ‘nokogiri.’ As per the instructions on the DreamHost wiki (http://wiki.dreamhost.com/Freezing_Gems) I froze the gems to vendors by coding them into my config file (config.gem “nokogiri”) and then used the rake gems:unpack command to build them into vendor.

I then froze the rails gems using rake rails:freeze:gems, and uploaded it to my subdomain.

The last seven lines of my backtrace go as follows:

0   /home/rclosner/demo.spubooks.com/vendor/rails/railties/lib/initializer.rb   336     in `abort'
1   /home/rclosner/demo.spubooks.com/vendor/rails/railties/lib/initializer.rb   336     in `check_gem_dependencies'
2   /home/rclosner/demo.spubooks.com/vendor/rails/railties/lib/initializer.rb   170     in `process'
3   /home/rclosner/demo.spubooks.com/vendor/rails/railties/lib/initializer.rb   113     in `send'
4   /home/rclosner/demo.spubooks.com/vendor/rails/railties/lib/initializer.rb   113     in `run'
5   ./config/environment.rb     9   
6   /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb     31  in `gem_original_require'
7   /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb     31  in `require'

My config file looks like this:

RAILS_GEM_VERSION = '2.3.3' unless defined? RAILS_GEM_VERSION
require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
config.gem "nokogiri"
config.gem "amazon-ecs"
config.time_zone = 'UTC'
end

Did I miss a step with the gems? Am I on the right track?

    Any gem that has native extensions can’t be vendored with your app, and there’s a good bet that on DH, config.gem won’t work right either. You have to install your own rubygems and make your app use it. I recommend taking a look at this:

    http://railstips.org/2008/11/24/rubygems-yours-mine-and-ours

    It has great instructions for setting up your environment on DH. I just had to do this last week after a server upgrade, and it still applies.
