ruby - そのようなファイルを読み込めません -- whois/server/adapters/verisign

Question

whois情報を出力する単純なRuby on Railsアプリを作成しようとしています。私はルビーの初心者なので、我慢してください。

require 'whois'
require 'whois-parser'

私のコントローラー：

class WhoisController < ApplicationController
  def index
    whois = Whois::Client.new    
    msg = {:token => whois.lookup("google.com")}
    render :json => msg
  end
end

エラーが発生します：

cannot load such file -- whois/server/adapters/verisign

編集：

whois google.com各フィールドの json 出力が必要なため、ruby パッケージ whois を実行する必要がある場合、システム コール whois を実行することを提案します。たとえば、「Registrar IANA ID」などを検索します。出力のwhois google.comは：

{"whois":"   Domain Name: GOOGLE.COM\n   Registry Domain ID: 2138514_DOMAIN_COM-VRSN\n   Registrar WHOIS Server: whois.markmonitor.com\n   Registrar URL: http://www.markmonitor.com\n   Updated Date: 2018-02-21T18:36:40Z\n   Creation Date: 1997-09-15T04:00:00Z\n   Registry Expiry Date: 2020-09-14T04:00:00Z\n   Registrar: MarkMonitor Inc.\n   Registrar IANA ID: 292\n   Registrar Abuse Contact Email: abusecomplaints@markmonitor.com\n   Registrar Abuse Contact Phone: +1.2083895740\n   Domain Status: clientDeleteProhibited https://icann.org/epp#clientDeleteProhibited\n   Domain Status: clientTransferProhibited https://icann.org/epp#clientTransferProhibited\n   Domain Status: clientUpdateProhibited https://icann.org/epp#clientUpdateProhibited\n   Domain Status: serverDeleteProhibited https://icann.org/epp#serverDeleteProhibited\n   Domain Status: serverTransferProhibited https://icann.org/epp#serverTransferProhibited\n   Domain Status: serverUpdateProhibited https://icann.org/epp#serverUpdateProhibited\n   Name Server: NS1.GOOGLE.COM\n   Name Server: NS2.GOOGLE.COM\n   Name Server: NS3.GOOGLE.COM\n   Name Server: NS4.GOOGLE.COM\n   DNSSEC: unsigned\n   URL of the ICANN Whois Inaccuracy Complaint Form: https://www.icann.org/wicf/\n\u003e\u003e\u003e Last update of whois database: 2019-02-02T02:42:36Z \u003c\u003c\u003c\n\nFor more information on Whois status codes, please visit https://icann.org/epp\n\nNOTICE: The expiration date displayed in this record is the date the\nregistrar's sponsorship of the domain name registration in the registry is\ncurrently set to expire.

EDIT #2 次のプレーンな古い Ruby の作品:

require "whois"
require "whois-parser"
require "json"

class MyWhoIs
  def initialize(site)
    @site = site
  end
  def index
    whois = Whois::Client.new
    record = Whois.whois("#{@site}")
    parser = record.parser
    puts parser.created_on
  end
end

who = MyWhoIs.new("google.com")
who.index

「1997-09-15 00:00:00 -0700」を出力します
