未初始化的常量 Faker::Date 更新到 rails 5.1

Question

当我尝试从 rails 5.0 更新到 5.1 时，我有一个工作应用程序。 （我一直在从 4.2 更新到 5.0）

它不再起作用了，运行如下命令：

rails server

产生错误。我不知道如何解决这个问题，也找不到任何信息，这很奇怪，因为它指向的是伪造者的代码，而不是我的。

这是控制台输出

这是我的文件： spring.rb

#!/usr/bin/env ruby

# This file loads spring without using Bundler, in order to be fast.
# It gets overwritten when you run the `spring binstub` command.

unless defined?(Spring)
  require 'rubygems'
  require 'bundler'

  if (match = Bundler.default_lockfile.read.match(/^GEM$.*?^    (?:  )*spring \((.*?)\)$.*?^$/m))
    Gem.paths = { 'GEM_PATH' => [Bundler.bundle_path.to_s, *Gem.path].uniq.join(Gem.path_separator) }
    gem 'spring', match[1]
    require 'spring/binstub'
  end
end

Faker 已经包含在 gemfile 中，我已经更新到最新版本。 宝石文件

gem 'faker', '~> 1.8', '>= 1.8.1'

这是我的 application.rb，（前 7 行） 应用程序.rb

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups) 
...

更新时出现问题。我已经从头开始完成了这个过程，现在它可以工作了。和faker没有关系。
