ruby on rails 4 - deploy - RVM, Capistrano 3 y el paquete falla

github capistrano

Question

Estoy usando Capistrano 3:

➜  webapp git:(rails) ✗ cap --version
Capistrano Version: 3.1.0 (Rake Version: 10.1.1)

Mi Capfile es:

# Load DSL and Setup Up Stages
require ''capistrano/setup''

# Includes default deployment tasks
require ''capistrano/deploy''

require ''capistrano/rails''
require ''capistrano/rvm''
require ''capistrano/bundler''
require ''capistrano/rails/assets''
require ''capistrano/rails/migrations''

# Loads custom tasks from `lib/capistrano/tasks'' if you have any defined.
Dir.glob(''lib/capistrano/tasks/*.cap'').each { |r| import r }

Y mi deploy.rb es:

set :rvm_type, :user 

set :application, "my_app"

set :scm, :git
set :repo_url,  ''[email protected]:nanounanue/my_app.git''
set :scm_passphrase, ""


set :ssh_options, {:forward_agent => true}
set :default_run_options, {:pty => true}
set :stages, ["vagrant"]
set :default_stage, "vagrant"


namespace :deploy do
  task :start do ; end
  task :stop do ; end
  desc ''Restart application''
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      run "sudo touch #{File.join(current_path,''tmp'',''restart.txt'')}" 
    end
  end

  after :publishing, :restart

  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

end

Como puede ver, estoy intentando implementar en una Vagrant VM .

El problema es que cuando ejecuto (cualquier) comando de Capistrano ocurre lo siguiente:

➜  webapp git:(rails) ✗ cap vagrant deploy --trace

No tengo idea de lo que está pasando ... ¿Tienes ideas antis?

EDITAR:

En la máquina virtual vagrant , .bash_profile es:

vagrant@vagrant-ubuntu-saucy-64:~$ cat .bash_profile 

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

EDITAR (25 de marzo de 2014):

Después de las sugerencias de @GhostGambler, el nuevo Capfile es:

set :default_environment, {
  ''PATH'' => "/usr/local/rvm/gems/ree-1.8.7-2012.02@<gemset>/bin:/usr/local/rvm/gems/ree-1.8.7-2012.02@global/bin:/usr/local/rvm/rubies/ree-1.8.7-2012.02/bin:/usr/local/rvm/bin:$PATH",
  ''RUBY_VERSION'' => ''ree-1.8.7-2012.02'',
  ''GEM_HOME''     => ''/usr/local/rvm/gems/ree-1.8.7-2012.02@<gemset>'',
  ''GEM_PATH''     => ''/usr/local/rvm/gems/ree-1.8.7-2012.02@<gemset>''
 #,
  #''BUNDLE_PATH''  => ''/usr/local/rvm/gems/ree-1.8.7-2012.02''  # If you are using bundler.
}



# Load DSL and Setup Up Stages
require ''capistrano/setup''

# Includes default deployment tasks
require ''capistrano/deploy''


require ''rvm1/capistrano3''

# Loads custom tasks from `lib/capistrano/tasks'' if you have any defined.
Dir.glob(''lib/capistrano/tasks/*.cap'').each { |r| import r }

Y agregué en deploy.rb

...

before ''deploy'', ''rvm1:install:gems'' 


namespace :deploy do
... 

El error aún aparece ( RVM is not a function... ) pero puede instalar las gemas, pero ahora falla con otro error:

Answer 1

¿Has oído hablar de rvm1-capistrano3 ?

Esto se instala poniendo en Gemfile

gem ''rvm1-capistrano3'', :require => false

(no olvide instalar paquete) y poner en Capfile

require ''rvm1/capistrano3''

Esto resolvió mis problemas de una vez.

Mientras modificas el Capfile debes eliminar (o comentar)

require ''capistrano/rvm''

ya que esto no es necesario con esta joya y puede romper cosas.
