Ruby on rails 4 capistrano部署没有这样的文件或目录

这是我的deploy.rb文件

require "bundler/capistrano"

set :rvm_ruby_string, "ruby-2.0.0-p247"
set :rvm_type, :user

set :application, "myproject"
set :repository,  "git@bitbucket.org:user/project.git"
set :user, "server-login-name"
set :branch, "master"
set :stages, %w{staging production}
require 'capistrano/ext/multistage'

set :deploy_via, :copy
set :use_sudo, true
set :rvm_install_with_sudo, true

default_run_options[:pty] = true

set :port, 2021

set :scm, :git

role :web, "mydomain.com"
role :app, "mydomain.com"
role :db,  "mydomain.com", :primary => true
role :db,  "mydomain.com"

after "deploy:update_code","deploy:config_symlink"

set :rvm_type, :system

# If you are using Passenger mod_rails uncomment this:
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

  task :config_symlink do
    #run "cp #{release_path}/config/database.yml.example #{release_path}/config/database.yml"
  end
end

before 'deploy', 'rvm:install_ruby'
before 'deploy', 'rvm:create_gemset'

My staging.rb和production.rb在单独的文件中包含以下内容

set :deploy_to, "/var/rails_apps/project_stage"
set :deploy_to, "/var/rails_apps/project"

现在我面临两个错误

1. triggering before callbacks for `deploy'
the task `rvm:install_ruby' does not exist

如果我评论

rvm:install_ruby

和

rvm:create_gemset

2. cannot open: no such file or directory for all my file and folders

我不明白为什么会这样。有人能帮忙吗？

RVM:install\u ruby在capistrano RVM中不是一件事吗？

我找不到你。你是什么意思？你在1中提到的任务。这个问题根本不存在。它们不是您正在使用的gem的功能。
