Rails 5.0.2，Capistrano停止部署

Question

我已经与Capistrano成功部署了几个月。经过一些更新后，它停止了工作。

最近我们添加了Spina CMS，但已经部署了一个现场版本。我们确实删除了Capistrano Lock一段时间。

如果我跑：

cap production deploy
(Backtrace restricted to imported tasks)
cap aborted!
Don't know how to build task 'start' (see --tasks)

Tasks: TOP => production
(See full trace by running task with --trace)

然后我跑了：

Daves-MBP-2:enduur dave$ cap production deploy --trace
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
cap aborted!
Don't know how to build task 'start' (see --tasks)

似乎问题是Deploy文件中的Puma任务。

这是我的capfile：

# Load DSL and set up stages
require "capistrano/setup"
require "capistrano/deploy"
require 'capistrano/rails'
require 'capistrano/bundler'
require 'capistrano/rvm'
require 'capistrano/puma'

# Include tasks from other gems included in your Gemfile
#
# For documentation on these, see for example:
#
#   https://github.com/capistrano/rvm
#   https://github.com/capistrano/rbenv
#   https://github.com/capistrano/chruby
#   https://github.com/capistrano/bundler
#   https://github.com/capistrano/rails
#   https://github.com/capistrano/passenger
#
# require 'capistrano/rvm'
# require 'capistrano/rbenv'
# require 'capistrano/chruby'
# require 'capistrano/bundler'
# require 'capistrano/rails/assets'
# require 'capistrano/rails/migrations'
# require 'capistrano/passenger'

# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

这是我的部署文件：

Answer 1

看起来这是一个Capistrano-puma问题 https://github.com/seuros/capistrano-puma/issues/213

将我的Capfile中的require行更改为以下版本：

require 'capistrano/puma'
install_plugin Capistrano::Puma
install_plugin Capistrano::Puma::Workers

Answer 2

不能将此添加为评论，因此对答案表示道歉，这不是答案。我今天将应用程序升级到5.0.2并成功部署，查看有关“不知道如何构建”错误的其他问题，它似乎指向了capfile中的'require'行。我建议你看看那个＆amp;确保一切顺利。
