Capistrano v3 could not find a Bundler

Question

I have a problem in deploying my App with Capistrano v3. When I run '$ cap production deploy' I see an error...

 INFO [825ad68d] Running /usr/bin/env bundle --gemfile /home/username/www/myapp/releases/20131026181031/Gemfile --path /home/username/www/myapp/shared/bundle --deployment --quiet --binstubs /home/username/www/myapp/shared/bin --without development test on myhostname.com

DEBUG [825ad68d]    /usr/bin/env: 
DEBUG [825ad68d]    bundle
DEBUG [825ad68d]    : No such file or directory

But when I run the last command...

cd /home/username/www/myapp/releases/20131026181031 && ( RAILS_ENV=production /usr/bin/env bundle --gemfile /home/username/www/myapp/releases/20131026181031/Gemfile --path /home/username/www/myapp/shared/bundle --deployment --quiet --binstubs /home/username/www/myapp/shared/bin --without development test )

... via ssh on my server I don't see any errors.

Here is my server's environment:

• Ubuntu 13.04
• rvm 1.23.5
• rubygems 1.8.25
• Bundler 1.3.5
• ruby 1.9.3p448
• capistrano (3.0.0)
• capistrano-bundler (1.0.0)
• capistrano-rails (1.0.0)

Here is a piece of my Gemfile which includes capistrano's gems

...
group :development do
  ...
  # Deploy with Capistrano
  gem 'capistrano', '~> 3.0.0'
  gem 'capistrano-rails'
  gem 'capistrano-bundler'
end
...

Please see below capistrano's configuration:

Capfile

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # Your restart mechanism here, for example:
      # execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end

  after :finishing, 'deploy:cleanup'
end

set :bundle_dir, -> { shared_path.join('bundle') }
set :bundle_flags, '--deployment --quiet'

role :db,  %w{myhostname.com}

server 'myhostname.com', user: 'username', roles: %w{web app}, my_property: :my_value

fetch(:default_env).merge!(rails_env: :production)

Please help me.

SOLVED

I've solved my problem by following steps:

Add capistrano-rvm into Gemfile and do

...
group :development do
  ...
  gem 'capistrano', '~> 3.0.0'
  gem 'capistrano-rails'
  gem 'capistrano-bundler'
  gem 'capistrano-rvm'
end
...

Add this line into Capfile

require 'capistrano/rvm'

Add these lines into the deploy.rb file.

set :rvm_ruby_version, '1.9.3-p448'
set :default_env, { rvm_bin_path: '~/.rvm/bin' }
SSHKit.config.command_map[:rake] = "#{fetch(:default_env)[:rvm_bin_path]}/rvm ruby-#{fetch(:rvm_ruby_version)} do bundle exec rake"

Solution

It seems that you had to add capistrano-rvm. It will take care about your ruby and bundler paths.

bundle install doesn't work from capistrano

possible duplicate of bundle install doesn't work from capistrano

I added capistrano-rvm and it solved the problem but another problem appeared. I think this one and previous one are similar (see below): DEBUG [3686e995] Command: cd /home/username/www/myapp/releases/20131027130646 && ( RVM_BIN_PATH=~/.rvm/bin RAILS_ENV= ~/.rvm/bin/rvm ruby-1.9.3-p448 do rake assets:precompile ) DEBUG [3686e995] /home/username/.rvm/gems/ruby-1.9.3-p448@global/gems/bundle‌​r-1.3.5/lib/bundler/‌​spec_set.rb:92:in block in materialize' DEBUG [3686e995] : DEBUG [3686e995] Could not find i18n-0.6.1 in any of the sources DEBUG [3686e995] ( DEBUG [3686e995] Bundler::GemNotFound

@ekondr As you can see, you haven't specified RAILS_ENV try to add set :rails_env, "production" instead of fetch(:default_env).merge!(rails_env: :production)

[ekondr]

I've added set :rails_env, "production" instead of fetch(:default_env).merge!(rails_env: :production) but nothing changed.

[ekondr]

I've fixed my problem. I've added these lines into the deploy.rb file. set :rvm_ruby_version, '1.9.3-p448' set :default_env, { rvm_bin_path: '~/.rvm/bin' } SSHKit.config.command_map[:rake] = "#{fetch(:default_env)[:rvm_bin_path]}/rvm ruby-#{fetch(:rvm_ruby_version)} do bundle exec rake"

[freemanoid]

@ekondr so all works as expected now? If migrations and assets compilation works well?

I don't see any instructions on that link for how to resolve. Good explanation of the problem though.
