安裝RSpec的問題

我目前正試圖自己教導如何使用帶rails的rspec測試。我是從這裏的博客下面的指南， http://everydayrails.com/2012/03/12/testing-series-rspec-setup.html ，來到這裏我無法運行該命令點「軌摹rspec的：安裝」安裝RSpec的問題

我拉閘得到的問題一大堆被

我的模型/ install.rb頁面

class Install < ActiveRecord::Base 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 
end

我的Gemfile頁面在這裏。

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

我的任何簡單的路線是

Rails.application.routes.draw do 
    devise_for :installs 
    resources :pins 
    root "pins#index" 
end

這裏是我的application.rb中的文件

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

我真的不知道還有什麼是需要證明的，但我真的很感激如果有人會爲我快速查看它。

您沒有列出的色器件寶石來安裝它。 – DVG

你的用戶模型是否包含相應的'devise'配置？ – zetetic

嗨@zetetic，我開始認爲這可能是問題的根源。你知道我可以檢查嗎？ – kdweber89

確認，該組之外，你有

gem "devise"

的devise_for路線助手是由色器件寶石提供。

而且不要忘了運行bundle install項目

因此，在我的寶石中，我添加了「寶石'設計'」，然後運行軟件包安裝。之後嘗試再次運行該命令「鐵軌生成rspec：安裝」並最終得到另一個錯誤。可能相關，「ynamic_matchers.rb：26：在'method_missing'：未定義的方法'devise'的安裝」我也嘗試了一個「寶石安裝設計」的頂部，並再次得到同樣的問題。你會碰巧知道該怎麼辦？ – kdweber89

你能用堆棧跟蹤來更新你的問題嗎？ – DVG

另外，我對你的上下文感到困惑，聽起來你已經在你的代碼庫中設計了一些東西，但它不在你的gem文件中，那些東西是如何到達的呢？你的模型名稱似乎也不會與jive你的教程 – DVG
