Question

我正在使用Nginx，Puma和Capistrano在VPS上部署Ruby on Rails应用程序，并且在初始部署期间出现错误。

我调查了错误（这告诉我validate不是一个函数），我找到了包含错误的文件，但找不到任何解决方案。

错误：

cap production deploy:initial --trace
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
cap aborted!
NoMethodError: undefined method `validate' for main:Object

default.rb文件的开头：

validate :application do |_key, value|
  changed_value = value.gsub(/[^A-Z0-9\.\-]/i, "_")
  if value != changed_value
    warn %Q(The :application value "#{value}" is invalid!)
    warn "Use only letters, numbers, hyphens, dots, and underscores. For example:"
    warn "  set :application, '#{changed_value}'"
    raise Capistrano::ValidationError
  end
end

%i(git_strategy hg_strategy svn_strategy).each do |strategy|
  validate(strategy) do |key, _value|
    warn(
      "[Deprecation Warning] #{key} is deprecated and will be removed in "\
      "Capistrano 3.7.0.\n"\
      "https://github.com/capistrano/capistrano/blob/master/UPGRADING-3.7.md"
    )
  end
end

你能帮我吗？谢谢:)
