【问题描述】：

我了解，此错误很常见，但不知何故我无法找出问题所在，似乎与路径有关。 我也关注了this 的问题，但到目前为止还没有运气。

宝石文件

group :development, :test do
  gem 'faker'
  gem 'rspec-rails', '~> 3.7'
  gem 'factory_bot_rails', '~> 4.0'
  gem 'shoulda-matchers', '~> 3.1'    
end

spec/factories/user.rb

FactoryBot.define do
  factory :user do
    name "Andy"
  end
end

spec/models/user_spec.rb

require 'rails_helper'

RSpec.describe User, type: :model do

it "should be invalid without phone number" do
    user = build(:user)
    user.phone = nil
    expect(user).not_to be_valid
  end
end

spec/support/factory_bot.rb

RSpec.configure do |config|
  config.include FactoryBot::Syntax::Methods
end

.rspec

--require spec_helper
--color

rails_helper.rb

require 'spec_helper'
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'rspec/rails'
require 'support/factory_bot'
...
...

我正在运行 bundle exec rspec spec/models/user_spec.rb

我尝试过的事情：

在rails_helper.rb 下方的require 'rspec/rails' 行中添加了require 'support/factory_bot'。 rails generate rspec:install（执行成功） rspec --init（执行成功） rake db:test:prepare（执行成功） 将 user_spec.rb 中的 require 'rails_helper' 更改为 require 'spec_helper'，但运行后出现错误 NameError: uninitialized constant User。

这是完整的跟踪：

【问题讨论】：

请显示您的 rails_helper 文件的内容。

另外，完整的堆栈跟踪也会有所帮助。

@moveson 添加了 rails_helper.rb

错误与哪一行有关？你能显示堆栈跟踪吗？

@Imran 在我的例子中，我创建了一个辅助模块 class 而不是 module。

【参考方案1】：

我搞定了。

除了一件事，一切都在原地。 将module 替换为class。 我有一个lib 和一个helper 模块导致错误。刚刚用class 替换了module，现在它像黄油一样运行。
