Capistrano與PHP

Question

我正在嘗試將本地計算機上的helloworld站點部署到服務器。 我已經安裝了Ruby，Rails和Capistrano。 有了食譜后，我鍵入此“ cap deploy：setup”命令並得到以下錯誤

/usr/lib/ruby/1.8/capistrano/configuration/variables.rb:122：in method_missing': undefined local variable or method for的method_missing': undefined local variable or method主method_missing': undefined local variable or method

以下是我的deploy.rb文件內容。

set :application, "testapp"
set :repository,  "<url of git repo>"
set :deploy_to, "var/www/html/testapp"
set :document_root, "var/www/html/testapp/current"

set :scm, :git
set :scm_username, "MyUserName"
set :scm_password, "MyPassword"
set :scm_checkout, "clone"
# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`

set :user, "<server's user name>"
set :password, "<server's password>"
set :use_sudo, false
set :ssh_options, {:forward_agent => true}

role :web, "<server's IP>"                          # Your HTTP server, Apache/etc
role :app, "<server's IP>"                          # This may be the same as your `Web` server
role :db,  "<server's IP>", primary => true # This is where Rails migrations will run

# If you are using Passenger mod_rails uncomment this:

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

    task :finalize_update do
        transaction do          
        end
    end

    task :symlink do
        transaction do
            run "ln -nfs #{current_release} #{deploy_to}/#{current_dir}"
            run "ln -nfs #{deploy_to}/#{current_dir} #{document_root}"
        end
    end

    task :migrate do
    end

    task :restart do
    end
end
