Question

我正在使用capistrano将我的rails 3.2.16 app部署到VPS服务器。这是我使用capistrano的时间，所以请考虑我是一个新手。当我运行“cap deploy：update”时我遇到了问题，我不知道该怎么做。

以下是发生的事情的终端输出：

这是我的deploy.rb文件，问题出在这里：

server '198.**.***.***', :web, :app, :db, primary: true

set :application, '*********'
set :user, '*********'
set :deploy_to, "/home/#{user}/app/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false

set :rvm_type, :user

set :scm, 'git'
set :repository, "git@bitbucket.org:*****/#{application}.git"
set :branch, `git rev-parse --abbrev-ref HEAD`.strip

set :shared_children, shared_children + %w{ config/application.yml }

default_run_options[:pty] = true
ssh_options[:forward_agent] = true

# Using Passenger
namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end
end


# Skipping Asset Compilation With Capistrano
# http://www.bencurtis.com/2011/12/skipping-asset-compilation-with-capistrano/
namespace :deploy do
  namespace :assets do
    task :precompile, :roles => :web, :except => { :no_release => true } do
      from = source.next_revision(current_revision)
      if capture("cd #{latest_release} && #{source.local.log(from)} vendor/assets/ app/assets/ | wc -l").to_i > 0
        run %Q{cd #{latest_release} && #{rake} RAILS_ENV=#{rails_env} #{asset_env} assets:precompile}
      else
        logger.info "Skipping asset pre-compilation because there were no asset changes"
      end
    end
  end
end

require "rvm/capistrano"
require "bundler/capistrano"

我做错了什么？

您的上限部署在部署中出现错误：资产：您已在deploy.rb中覆盖的预编译任务请在您从deploy.rb评论以下给定代码后尝试运行上限部署

namespace :deploy do

  namespace :assets do

  task :precompile, :roles => :web, :except => { :no_release => true } do
    from = source.next_revision(current_revision)
    if capture("cd #{latest_release} && #{source.local.log(from)} vendor/assets/  app/assets/ | wc -l").to_i > 0
    run %Q{cd #{latest_release} && #{rake} RAILS_ENV=#{rails_env} #{asset_env} assets:precompile}
    else
      logger.info "Skipping asset pre-compilation because there were no asset changes"
    end
  end
end
