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，我有一个正常工作的应用程序。 （我已经从4.2更新到5.0）

它不再起作用，运行如下命令：

rails server

产生错误。我不知道如何解决这个问题，而且我没有找到任何信息，这很奇怪，因为它指向了faker的代码，而不是我的代码。

这是控制台输出

这是我的档案： 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已包含在gemfile中，我已更新到上一版本。 的Gemfile

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

这是我的application.rb，（前7行） application.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。我从头开始完成这个过程，现在它可以工作了。它与faker无关。
