Rails 3.1 и Asset Pipeline: проблемы с развертыванием с помощью Capistrano

Я только что перешел с Ruby on Rails 3.0.10 на 3.1.0 и хотел бы развернуть свои файлы активов с помощью драгоценного камня Capistrano (моя локальная машина — MacOs под управлением Snow Leopard, моя удаленная машина работает под управлением Ubuntu 10.04 Lucid). Итак, как написано в Официальном руководстве, я раскомментировал load 'deploy/assets' в моем Capfile нравится:

# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'

Теперь, когда я запускаю команду cap deploy, я получаю следующую ошибку (ошибка объясняется внизу):

Итак, я попытался решить проблему, следуя ответу на этот вопрос:

# Rakefile
require 'rake/dsl_definition'

require File.expand_path('../config/application', __FILE__)

<MyApplicationName>::Application.load_tasks

После повторного запуска команды cap deploy я получаю следующую ошибку:

Где код, относящийся к Capistrano, неверен? Как правильно использовать оператор load 'deploy/assets', чтобы процесс развертывания работал?

Используете ли вы последние драгоценные камни Capistrano и Rake?   -  person Richard Hulse    schedule 26.09.2011

@Richard Hulse - Да, я так думаю: $ rake -V # => rake, version 0.9.2, $ cap -V # => Capistrano v2.8.0.   -  person Backo    schedule 26.09.2011

что происходит, когда вы запускаете rake RAILS_ENV=production RAILS_GROUP=assets assets:precompile на своей машине разработки?   -  person ErsatzRyan    schedule 03.10.2011

Пробовали ли вы просто определить свою собственную задачу? Именно это я и сделал, , когда столкнулся с этой проблемой:

task :precompile, :role => :app do  
  run "cd #{release_path}/ && rake assets:precompile"  
end  
after "deploy:finalize_update", "deploy:precompile"

Для этого вам потребуется инициализация RVM, если вы используете RVM
