ruby-on-rails-3 - カピストラーノ接続の問題

Question

cap deploy:setupRails プロジェクト ディレクトリで 実行しようとすると、このエラーが発生します。

私のCapfileはこれです：

load 'deploy'
# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'
load 'config/deploy' # remove this line to skip loading any of the default tasks



set :application, "myapp"

set :repository, "file://~/git/#{application}.git"
set :local_repository, "myserver:~/git/#{application}.git"
set :branch, "master"

set :scm, :git


set :deploy_to, "/var/www"

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


set :user, "me"
ssh_options[:keys] = %w(~/.ssh/id_rsa)

set :port, 33333


server "example.com", :app, :web, :db, :primary => true

このエラーは本当に私を夢中にさせています。公開/秘密キーを使用してサーバーに正常にsshでき、sshdはリモートホストのデフォルト以外のポートでリッスンするように設定されていることに注意してください（したがって、set :port行）。
