I'm currently trying to deploy a Rails 4 app using Capistrano 3. All going smoothly but I've got an issue, yeah ! I can't run any rails commands in my app.

Here is my related capistrano plugins :

gem 'capistrano-rails'
gem 'capistrano-unicorn-nginx'
gem 'capistrano-rbenv'
gem 'capistrano-secrets-yml'
gem 'capistrano-rails-console'

So when I run a cap production rails:console it give me this output:

    [b2458a1e] Running /usr/bin/env [ -d ~/.rbenv/versions/2.1.1 ] as [email protected]
DEBUG [b2458a1e] Command: [ -d ~/.rbenv/versions/2.1.1 ]
DEBUG [b2458a1e] Finished in 0.528 seconds with exit status 0 (successful).

Any idea ?

update 13/03 - add deploy.rb

# config valid only for current version of Capistrano
lock '3.3.5'

set :application, 'my_app'
set :repo_url, '[email protected]:foo/my_app.git'

# Default branch is :master
# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }.call
set :branch, 'master'

# Default deploy_to directory is /var/www/my_app_name
set :deploy_to, '/var/www/my_app'

# Default value for :linked_files is []
set :linked_files, fetch(:linked_files, []).push('config/database.yml')

# Default value for linked_dirs is []
set :linked_dirs, fetch(:linked_dirs, []).push('bin', 'log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system')

set :rbenv_ruby, '2.1.1'

I think the problem is that you are missing bin/rails in the deployed copy of your Rails app. Here's what I would do:

Make sure the contents of your bin directory are added, committed, and pushed to your git repository. This will include bin/rails and bin/rake.
Remove bin from Capistrano's :linked_dirs setting in your deploy.rb.
Re-deploy.
