我的Capfile：
# Load DSL and Setup Up Stages
require 'capistrano/setup'
# Includes default deployment tasks
require 'capistrano/deploy'
# Includes tasks from other gems included in your Gemfile
# If you are using rbenv add these lines:
require 'capistrano/rbenv'
set :rbenv_type, :user # or :system, depends on your rbenv setup
set :rbenv_ruby, '2.3.1'
require 'capistrano/bundler'
require 'capistrano/rails'
# require 'capistrano/passenger'
# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }
我被困住了，不知道为什么会中止上限。
有什么想法吗？
