Ruby on rails 4 Webfaction上的Capistrano3-未找到捆绑包

我正在为我的rails项目使用webfection。当我运行deploy时，会出现一些错误

SSHKit:：Runner:：ExecuteError:在主机web412.webpartion.com上执行时出现异常：cd/home/USER/webapps/PROHJECT/releases/20140906100427&&bundle安装--无开发测试退出>状态：127 cd/home/unrealm/webapps/minecraft_评级/发行版/20140906100427&&bundle安装版——无 未找到开发测试stderr:bash:bundle:命令

许多常见问题-

“设置默认环境”，确定，已设置

set :default_env, {
    'PATH' => "#{deploy_to}/bin:$PATH",
    'GEM_HOME' => "#{deploy_to}/gems",
    'RUBYLIB' => "#{deploy_to}/lib"
}

但它不起作用

我的deploy.rb

namespace :deploy do
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      execute "#{deploy_to}/bin/restart"
    end
  end

  task :bundle do
    on roles(:app) do
      execute "cd #{deploy_to} && bundle install --without development test"
    end
  end

  after :publishing, :bundle
  after :bundle, :restart

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end
end

Capistrano无法在服务器上安装捆绑包。请检查打包机
