Puma：未找到状态文件

Question

我正在尝试使用 Capistrano 部署 Rails 应用程序。我有一个问题bundler: command not found: pumactl，我似乎已经通过将 puma gem 添加到:development组外的 Gemfile 中解决了这个问题。

文件

source 'https://rubygems.org'

gem 'rails', '4.2.0'
gem 'sass-rails', '~> 5.0'
gem 'semantic-ui-sass', github: 'doabit/semantic-ui-sass'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'mongoid'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'prawn-rails', '0.1.1'
gem 'fastimage', '1.6.6'
gem 'mini_magick', '4.0.4'
gem 'carrierwave', '0.10.0'
gem 'puma', '2.11.1'

group :development, :test do
  gem 'capistrano', '3.3.5'
  gem 'capistrano-rvm', '0.1.2'
  gem 'capistrano-rails', '1.1.2'
  gem 'capistrano-bundler', '1.1.4'
  gem 'capistrano3-puma', '0.8.5'
  gem 'web-console', '~> 2.0'
  gem 'spring'
end

现在，当我尝试cap production deploy:initial --trace（或cap production deploy --trace）时，我得到以下输出：

...
INFO [7314ca0d] Running ~/.rvm/bin/rvm default do bundle exec pumactl -S /home/myuser/apps/myapp/shared/tmp/pids/puma.state restart as myuser@mydomain.com

我试图遵循本教程。

有什么建议？

这个问题通常是由于之前尝试使用不同的 gemcapistrano-puma而不是capistrano3-puma. 请参阅此 Github 问题。

就我而言，gem uninstall capistrano-puma即使它没有包含在我的 Gemfile 中，我也不得不这样做。感谢@seuros的帮助。
