Question

我的Rails项目中有一个gem，非常简单，它将ip地址转换为真实地址（例如Gem.locate '127.0.0.1'返回{ country: 'de' }

代码就像这样

ip_locator / lib / service.rb

module IpLocator
  class Service
    include Singleton

    attr_reader :db
    def initialize
      @db = MaxMindDB.new('db/GeoLite2-City.mmdb')
    end

    def locate(ip)
      db.lookup ip
    end
  end
end

当我进入rails项目时，我可以正确地执行此操作：IpLocator::Service.instance.locate '74.125.225.224'并获取我需要的信息。
现在我正在尝试为gem添加一些测试（不在rails项目中）。

require 'spec_helper'

RSpec.describe IpLocator do
  describe 'ip_locator' do
    context 'when the data exists' do
      let(:ip) { '74.125.225.224' }
      subject do
        IpLocator::Service.instance.locate ip
      end
      it 'return country data' do
        expect(subject.found).to be_truthy
      end
    end
  end
end

但是当我运行测试时，我得到了

  1) IpLocator ip_locator when the data exists return country data
     Failure/Error: IpLocator::Service.instance.locate ip

     NameError:
       uninitialized constant IpLocator::Service

我已尝试将IpLocator::Service更改为Service，我在规范文件中尝试了ip_locator（尽管spec_helper.rb中已经需要{}}。我很确定我做的事情非常愚蠢但不确定究竟是什么

这是我的spec_helper.rb

require 'bundler/setup'
Bundler.setup
require 'byebug'
require 'ip_locator'
Dir[File.dirname(__FILE__) + '/lib/*.rb'].each { |file| require file }

RSpec.configure do |config|
  # Enable flags like --only-failures and --next-failure
  config.example_status_persistence_file_path = '.rspec_status'

  # Disable RSpec exposing methods globally on `Module` and `main`
  config.disable_monkey_patching!

  config.expect_with :rspec do |c|
    c.syntax = :expect
  end
end

我看到了错误：

NameError: uninitialized constant IpLocator::Service::Singleton
Did you mean?  SignalException

然后，如果我在spec_helper中尝试要求singleton，我会得到

  1) IpLocator::Service ip_locator when the data exists return country data
     Failure/Error: @db = ::MaxMindDB.new('db/GeoLite2-City.mmdb')

     NameError:
       uninitialized constant MaxMindDB

我疯了
