我正在尝试将我的第一个 rails 应用程序部署到 VPS。到目前为止，我已经用 ubuntu、postgresql、node、ruby 等配置了它，并且运行cap deploy:setup命令没有错误。当我尝试运行cap deploy:cold时，我收到一个有趣的捆绑程序错误，它说由于缺少 gem 而无法继续，即使它在 gemfile 中也是如此。我正在 Windows 7 上开发，因此无法与 unicorn 捆绑，并将此 gem 放入 gem 文件中的组中：

group :production do
    if RUBY_PLATFORM =~ /win32/
      gem "pg", :platform => [:mswin, :mingw]
    else
      gem "pg", :platform => :ruby
      gem 'unicorn'
    end
end

这是我运行时得到的一些输出cap deploy:cold：

任何帮助都非常感谢，经过几天的努力，我准备放弃了！非常感谢。

在你的Gemfile：

group :production do 
  gem 'pg'
  gem 'unicorn'
end

删除:platform => :ruby.

编辑：尝试在服务器上指定环境：

export RAILS_ENV=production
