ruby-on-rails – 在使用capistrano部署后,Rails 4不会检测应用

这是我的相关capistrano插件：

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

所以当我运行一个cap生产rails：console它给我这个输出：

[b2458a1e] Running /usr/bin/env [ -d ~/.rbenv/versions/2.1.1 ] as user@x.x.x.x
DEBUG [b2458a1e] Command: [ -d ~/.rbenv/versions/2.1.1 ]

任何的想法 ？

更新13/03 – 添加deploy.rb

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

set :application,'my_app'
set :repo_url,'git@github.com: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'
