deploy can't find asset folders in the public dir - ruby-on-rails-3

Question

I'm using ror 3.1 rc4, somehow when I deploy into a production server, the directories for images, stylesheets, and javascript are not found, and deployment fails. I do have the necessary code in deploy.rb
namespace :deploy do
task :start do ; end
task :stop do ; end
desc "Restarting mod_rails with restart.txt"
task :restart, :roles => :app, :except => { :no_release => true } do
run "touch #{current_path}/tmp/restart.txt"
end
task :precompile do
run "cd #{release_path}; RAILS_ENV=production rake assets:precompile"
end
end
after 'deploy:update_code', 'deploy:precompile'
And here is the error I get
executing "find /var/www/nattyvelo/releases/20110624033801/public/images /var/www/nattyvelo/releases/20110624033801/public/stylesheets /var/www/nattyvelo/releases/20110624033801/public/javascripts -exec touch -t 201106240338.03 {} ';'; true"

Answer 1

There's two errors happening here.
The first is that there is no longer a public/images, public/stylesheets or public/javascripts folder within a Rails 3.1 application. They have all been moved into app/assets. However, if you run rake assets:precompile then there will be a public/assets folder. This is where the static assets for your application will be served out of.
Whatever it is in your deploy script that is referencing these three folders needs to stop doing so or otherwise you'll continue to get this error.
The second error is that, just like the two other people before me have kind of suggested, you need to have the Bundler gem installed on the server.

Answer 2

You have a PATH problem by the look of it:
** [out :: 66.228.39.243] bash: bundle: command not found
You need to fix your PATH environment variable.

Answer 3

You probably have to install bundler in the production server.
sudo gem install bundler
