Deploying Ruby on rails on Deamhost fails

Question

I'm trying to deploy a simple Ruby on Rails app to dreamhost but I'm getting an error related to the bundle command. Here is the error:

    servers: ["bullseye.dreamhost.com"]
    [bullseye.dreamhost.com] executing command
    command finished

Here is my deploy.rb file.

require 'bundler/capistrano'

set :user, "MY-USERNAME"
set :password, "MY-PASSWORD"
set :domain, 'bullseye.dreamhost.com'  # Dreamhost servername where your account is located 
set :project, 'blog'  # Your application as its called in the repository
set :application, 'MY-DOMAIN'  # Your app's location (domain or sub-domain name as setup in panel)
set :applicationdir, "/home/#{user}/#{application}"  # The standard Dreamhost setup

# version control config
set :scm_username, 'MY-SVN-USERNAME'
set :scm_password, 'MY-SVN-PWD'
set :repository, "http://MY-SVN-URL/01/blog/"

# roles (servers)
role :web, domain
role :app, domain
role :db,  domain, :primary => true

# deploy config
set :deploy_to, applicationdir
set :deploy_via, :export

# additional settings
default_run_options[:pty] = false  # Forgo errors when deploying from windows

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end
end

I found a similar question at Bundle install failing when deploying a Rails 3 app to Dreamhost with Capistrano but the solution didn't work. Anybody have any ideas as to what might be happening in my case?

Answer 1

Besides adding the path to bundle, as specified above, I also had to add the following line to my config/deploy.rb in order to force capistrano to use bash, instead of the default shell, which, on dreamhost, is dash:

set :shell, '/bin/bash'

Answer 2

I got this figured out eventually. What I did was

• ssh into the dreamhost server and execute which bundle command
• from ssh session execute echo $PATH command

• edit config/deploy.rb and combine both strings with a : between and place inside default_environment PATH value, see below

  set :default_environment, { 'PATH' => "'/usr/lib/ruby/gems/1.8/bin//bundle:/home/sayed3/.gems/bin:/usr/lib/ruby/gems/1.8/bin/:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games'" }

Once I did this it was able to execute the bundle command successfully, but then I started running into some other issues. I eventually decided to use a VPS that I have hosted elsewhere, but I'm sure if I spent a bit more time I could have figured it out.
