如何拼合YAML文件，使其没有别名(在ruby中)？

require 'yaml'

def remove_aliases(yaml_file)
  yaml_data = YAML.load_file(yaml_file)
  yaml_data = remove_aliases_recursive(yaml_data)
  File.open(yaml_file, 'w') { |file| file.write(yaml_data.to_yaml) }
end

def remove_aliases_recursive(data)
  case data
  when Array
    data.map { |item| remove_aliases_recursive(item) }
  when Hash
    data.each_with_object({}) do |(key, value), hash|
      hash[key] = remove_aliases_recursive(value)
    end
  else
    data
  end
end

# 拼合并去除别名的示例
yaml_file = 'example.yaml'
remove_aliases(yaml_file)
