我目前正在尝试自学如何使用rails进行rspec测试。我在这里关注博客的指南， http://everydayrails.com/2012/03/12/testing-series-rspec-setup.html 并且到了我无法运行命令的程度 “rails g rspec：install”
我最终得到了许多问题

我的models / install.rb页面是
class Install < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end
我的Gemfile页面在这里。
source 'https://rubygems.org'
gem 'rails', '4.2.1'
gem 'haml', '~> 4.0.5'
gem 'bootstrap-sass', '~> 3.2.0.2'
gem "spring-commands-rspec"
gem 'simple_form', '~> 3.0.2'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'devise'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
gem 'spring', group: :development
end
group :development, :test do
gem 'rspec-rails'
gem 'factory_girl_rails'
end
group :test do
gem 'faker'
gem 'capybara'
gem 'guard-rspec'
gem 'launchy'
end
我的任何简单路线都是
Rails.application.routes.draw do
devise_for :installs
resources :pins
root "pins#index"
end
这是我的application.rb文件
require File.expand_path('../boot', __FILE__)
require 'rails/all'
Bundler.require(*Rails.groups)
module MyApp
class Application < Rails::Application
config.active_record.raise_in_transactional_callbacks = true
end
end
老实说，我不确定还需要展示什么，但如果有人能为我快速浏览一下，我会非常感激。

确保在群组之外有
gem "devise"
devise_for路由助手由设计宝石提供。
不要忘记运行bundle install将其安装到项目中
