Ошибка Capistrano во время установки установки

Question

Я новичок в Rails и Capistrano. Я пытаюсь установить Rails-приложение на нашем демонстрационном сервере, и я столкнулся с ошибкой во время развертывания крышки: setup. Ошибка: камни/Capistrano-2.11.2/Библиотека/Capistrano/конфигурация/callbacks.rb: 105: в `на ': просьба указать только имя задачи или блок, но не оба (ArgumentError)

Я не уверен, где искать, чтобы исправить это. Любая помощь будет очень оценена.

Вот развернуть/demo.rb

# server-based syntax 
# ====================== 
# Defines a single server with a list of roles and multiple properties. 
# You can define all roles on a single server, or split them: 

# server 'example.com', user: 'deploy', roles: %w{app db web}, my_property: :my_value 
# server 'example.com', user: 'deploy', roles: %w{app web}, other_property: :other_value 
# server 'db.example.com', user: 'deploy', roles: %w{db} 

server 'demo1.demo.com', user: 'demo-admin', roles: %w{web app db} 


# role-based syntax 
# ================== 

# Defines a role with one or multiple servers. The primary server in each 
# group is considered to be the first unless any hosts have the primary 
# property set. Specify the username and a domain or IP for the server. 
# Don't use `:all`, it's a meta role. 

# role :app, %w{deploy@example.com}, my_property: :my_value 
# role :web, %w{user1@primary.com user2@additional.com}, other_property: :other_value 
# role :db, %w{deploy@example.com} 

role :app, %w{demo-admin@demo1.demo.com} 
role :web, %w{demo-admin@demo1.demo.com} 
role :db, %w{demo-admin@demo1.demo.com} 



# Configuration 
# ============= 
# You can set any configuration variable like in config/deploy.rb 
# These variables are then only loaded and set in this stage. 
# For available Capistrano configuration variables see the documentation page. 
# http://capistranorb.com/documentation/getting-started/configuration/ 
# Feel free to add new variables to customise your setup. 

set :rails_env, 'demo' 
set :migrate_env, 'demo' 
set :rvm_ruby_version, '2.2.1@evcc' 
set :passenger_rvm_ruby_version, '2.2.1' 

#set :branch, 'develop' 



# Custom SSH Options 
# ================== 
# You may pass any option but keep in mind that net/ssh understands a 
# limited set of options, consult the Net::SSH documentation. 
# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start 
# 
# Global options 
# -------------- 
# set :ssh_options, { 
# keys: %w(/home/rlisowski/.ssh/id_rsa), 
# forward_agent: false, 
# auth_methods: %w(password) 
# } 
# 
# The server-based syntax can be used to override options: 
# ------------------------------------ 
# server 'example.com', 
# user: 'user_name', 
# roles: %w{web app}, 
# ssh_options: { 
#  user: 'user_name', # overrides user setting above 
#  keys: %w(/home/user_name/.ssh/id_rsa), 
#  forward_agent: false, 
#  auth_methods: %w(publickey password) 
#  # password: 'please use keys' 
# } 

Вот это deploy.rb поднимается

#config valid only for current version of Capistrano 
#lock '3.4.0' 

set :application, 'my_app' 
set :repo_url, 'git@bitbucket.org:foo/my_app.git' 

# Default branch is :master 
# ask :branch, `git rev-parse --abbrev-ref HEAD`.chomp 

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

# Default value for :scm is :git 
set :scm, :git 

# Default value for :format is :pretty 
# set :format, :pretty 

# Default value for :log_level is :debug 
# set :log_level, :debug 

# Default value for :pty is false 
# set :pty, true 

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

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

# Default value for default_env is {} 
# set :default_env, { path: "/opt/ruby/bin:$PATH" } 

# Default value for keep_releases is 5 
set :keep_releases, 5 

set :migrate_target, :latest 

# Restart using 'passenger-config restart-app' 
set :passenger_restart_with_touch, false 

namespace :deploy do 

    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

Эта ошибка, если вы используете одну из следующих on :after, ... или on :before .... Проверьте, если один из ваши файлы имеют этот код с grep -rnP "on :before|on :after" conifg/
