Ruby 调试“没有要加载的文件--spec_helper”

菜鸟可能会错过一些明显的东西...... 我正在尝试调试 Rspec 文件。此时 Rspec 文件已被删除：

  require 'spec_helper'

  describe PagesController do

    render_views

    describe "GET 'home'" do
        describe "when not signed in" do

        before(:each) do
          get :home
        end

        it "should be successful" do
          response.should be_success
        end

        it "should have a vendor section" do
          response.should have_selector("h1", :content => "Vendor")
        end

        it "should have a hospital section" do
          response.should have_selector("h1", :content => "Hospital")
        end
    end
  end

我从命令行进行以下调用：

rdebug spec/controllers/pages_controller_spec.rb

调试器运行，但抛出以下错误：

> require 'spec_helper'

    <internal:lib/rubygems/custom_require>:29:in `require'
    <internal:lib/rubygems/custom_require>:29:in `require'

Uncaught exception: no such file to load -- spec_helper

没有调试器的 Rspec 没有问题。我正在使用 Rspec 2.3.0、ruby-debug19 (0.11.6)、Rails 3.0.3 和 ruby​​ 1.9.2。为什么调试器看不到spec_helper 文件？

确保你已经跑了

rails generate rspec:install

创建spec_helper.rb 文件。
