rspec 核心 Ruby Rails

Question

您好，我正在使用 rspec:

测试我的应用程序

这是测试文件。

require 'spec_helper'

describe RecipesController do
    render_views
    describe "index" do
        before do
            Recipe.create!(name: "Spaghetti alla Carbonara")
            Recipe.create!(name: "Spaghetti alle vongole e cozze")
            Recipe.create!(name: "Bistecca")
            Recipe.create!(name: "Fritto")

            xhr :get, :index, format: :json, keywords: keywords
        end

        subject(:results) { JSON.parse(response.body) }

        def extract_name 
            ->(object){ object["name"] } 
        end

        context 'quando la ricerca riporta dei risultati' do
            let(:keywords) { 'Spaghetti' }
            it 'essere 200' do
                expect(response.status).to eq(200)
            end

            it 'deve ritornare due risultati' do
                expect(results.size).to eq(2)
            end

            it 'deve esserci la ricetta Spaghetti alla Carbonara' do
                expect(results.map(&extract_name)).to include('Spaghetti alla Carbonara')
            end

            it 'deve esserci la ricetta Spaghetti alle vongole e cozze ' do
                expect(results.map(&extract_name)).to include('Spaghetti alle vongole e cozze')
            end
        end

        context 'quando la ricerca non riporta alcun risulato' do
            let(:keywords) { 'tortellini' }
            it 'non deve ritornare alcun risulato' do
                expect(results.size).to eq(0)
            end
        end


    end
end

当我尝试通过命令启动测试时：

rake db:migrate RAILS_ENV=test ; rspec spec/controllers/recipes_controller_spec.rb

我收到这个错误

/var/lib/gems/2.1.0/gems/bundler-1.10.1/lib/bundler/runtime.rb:34:in block in setup': You have already activated rspec-core 3.3.1, but your Gemfile requires rspec-core 2.99.2. Prependingbundle exec` to your command may solve this. (Gem::LoadError)

如日志中所述，错误与 rspec-core v3.3.1 有一些冲突，所以在我的 gem 文件中我添加了这一行以安装 rspec -核心 v2.99.2

gem 'rspec-core', '~> 2.99.2'

但如果我再次启动该命令（在捆绑包安装之后并使用捆绑包执行），结果是一样的。有人有类似的问题吗？

你尝试了吗？

bundle exec rake db:migrate RAILS_ENV=test
bundle exec rspec spec/controllers/recipes_controller_spec.rb
