Question

我正在将带有Capistrano的Rails 3.2.2，Ruby 1.9.3应用程序部署到Linux服务器上。当我运行cap deploy时，我收到此错误：

  * executing `deploy:assets:precompile'
  * executing "cd /var/www/production/releases/20120418090209 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile"
    servers: ["example.com"]
    [example.com] executing command
    [example.com] sh -c 'cd /var/www/production/releases/20120418090209 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile'
 ** [out :: example.com] rake aborted!
 ** [out :: example.com] cannot load such file -- ruby-debug
 ** [out :: example.com] 
 ** [out :: example.com] (See full trace by running task with --trace)
    command finished in 8962ms
*** [deploy:update_code] rolling back
  * executing "rm -rf /var/www/production/releases/20120418090209; true"
    servers: ["example.com"]
    [example.com] executing command
    [example.com] sh -c 'rm -rf /var/www/production/releases/20120418090209; true'
    command finished in 176ms
failed: "sh -c 'cd /var/www/production/releases/20120418090209 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile'" on example.com

它说，找不到ruby-debug宝石。但ruby-debug不在我的Gemfile中的生产组中：

group :development, :test do
  gem "steak"
  gem "linecache19", :git => "git://github.com/mark-moseley/linecache", :require => "ruby-debug"
  gem "ruby-debug-base19x", "~> 0.11.30.pre4"
  gem "ruby-debug19"
  gem "rails_best_practices"
  gem "ruby_parser"
  gem "reek"
  gem "flog"
  gem "jslint_on_rails", :git => "git://github.com/psionides/jslint_on_rails"
  gem "jasmine-rails"
end

导致rake assets:precompile命令后抛出错误，我认为它与Capistrano和我的Capfile中的load 'deploy/assets'调用有关：

load 'deploy' if respond_to?(:namespace) # cap2 differentiator
Dir['config/deploy/recipes/*.rb','vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy' # remove this line to skip loading any of the default tasks
# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'

当我删除这一行时，一切都很好，但（当然）资产在生产中找不到。而且，如果我直接在服务器上运行bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile（在app目录内），我会得到同样的错误。

那我该怎么办？

ruby-debug已过时。在ruby＆gt; = 1.9中，你应该使用优秀的debugger gem 请参阅：https://github.com/cldwalker/debugger和http://railscasts.com/episodes/54-debugging-ruby-revised

没有找到Capistrano部署，资产管道，ruby-debug
