我尝试使用Capistrano，但我总是遇到一些错误。有以下Capfile：
# Load DSL and Setup Up Stages
require 'capistrano/setup'
# Includes default deployment tasks
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails'
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
deploy.rb：
lock '3.2.1'
set :application, 'superuser_web_app'
set :repo_url, 'git@github.com:some_repo'
set :deploy_to, 'some_path'
set :branch, 'develop'
set :rails_env, 'development'
set :deploy_via, :copy
set :stages, ["production"]
production.rb：
server 'Some IP', user: 'concierge', roles: %w{app web db}
错误日志：
