Rails 4 Capistrano部署无法找到有效的支持

Question

我试图通过Capistrano从本地计算机部署到我的部署服务器。当我部署时，它连接到服务器，然后丢弃以下信息。

** sftp upload /var/folders/x0/hyzt7pms0599ymtyjft739kw0000gn/T/20160406223514.tar.gz -> /tmp/20160406223514.tar.gz

failed: "sh -c 'cd -- /var/www/address/releases/20160406223514 && RAILS_ENV=production RAILS_GROUPS=assets rake assets:precompile'" on address 

它说，它无法找到的ActiveSupport，但是当我在服务器上运行的宝石列表，它列出，并显示版本4.2.6，4.2.4，4.2.0。

这是一个权限问题？

这里是deploy.rb

set :application, "app" 
set :repository, "repo" 

set :deploy_to, '/var/www/address' 
set :scm, :git 
set :branch, "master" 

set :user, "user" 

set :use_sudo, false 

set :rails_env, "production" 
set :deploy_via, :copy 

set :keep_releases, 5 

default_run_options[:pty] = true 

server "address", :app, :web, :db, :primary => true 


namespace :deploy do 
    desc "Symlink shared config files" 
    task :symlink_config_files do 
     run "#{ try_sudo } ln -s #{ deploy_to }/shared/config/database.yml #{ current_path }/config/database.yml" 
    end 

    desc "Restart Passenger app" 
    task :restart do 
     run "#{ try_sudo } touch #{ File.join(current_path, 'tmp', 'restart.txt') }" 
    end 
end 


after "deploy", "deploy:symlink_config_files" 
after "deploy", "deploy:restart" 
after "deploy", "deploy:cleanup"

我的猜测是，你似乎并没有试图做资产预编译之前推出在Capistrano的脚本bundle install。

预先运行软件包安装，它应该工作正常。

编辑：require 'capistrano/rails'（或require 'capistrano/bundler'）在您的Capfile里面。
