Ruby on rails Ruby中的Rspec加载错误

我正在学习Hartl的RubyonRails教程，试图测试用户注册时是否有无效信息，运行rspec时出现“加载错误”。我不确定如何修复这个错误，因为我已经更新了我的gem文件

$ bundle exec rspec spec/requests/user_pages_spec.rb \ > -e "signup with invalid information"

然后我得到这个信息：

/Users/kelvinyu/.rvm/gems/ruby-2.0.0-p247@railstutorial_rails_4_0/gems/rspec-core-2.13.1/lib/rspec/core/configuration.rb:819:in `load': cannot load such file -- /Users/kelvinyu/rails_projects/sample_app/signup with invalid information (LoadError)

以下是我的规范/请求/用户页面\u spec.rb：

require 'spec_helper'

describe "UserPages" do

  subject { page }

  describe "profile page" do
    let(:user) { FactoryGirl.create(:user) }
    before { visit user_path(user) }

    it { should have_content(user.name) }
    it { should have_title(user.name) }
  end

  describe "signup page" do
    before { visit signup_path }
      # Run the generator again with the --webrat flag if you want to use webrat methods/matchers
    it { should have_content('Sign up') }
    it { should have_title(full_title('Sign up')) }
  end

  describe "signup" do

    before { visit signup_path }

    let(:submit) { "Create my account" }

    describe "with invalid information" do
      it "should not create a user" do
        expect { click_button submit }.not_to change(User, :count)
      end
    end

    describe "with valid information" do
      before do
        fill_in "Name",         with: "Example User"
        fill_in "Email",        with: "user@example.com"
        fill_in "Password",     with: "foobar"
        fill_in "Confirmation", with: "foobar"
      end

      it "should create a user" do
        expect { click_button submit }.to change(User, :count).by(1)
      end
    end
  end
end

我是否遗漏了其他信息？修复此错误的适当步骤是什么

编辑：

此处的等级库帮助器：

require 'spec_helper'
# Specs in this file have access to a helper object that includes
# the StaticPagesHelper. For example:
# describe StaticPagesHelper do
#   describe "string concat" do
#     it "concats two strings with spaces" do
#       helper.concat_strings("this","that").should == "this that"
#     end
#   end
# end
#describe StaticPagesHelper do
#   pending "add some examples to (or delete) #{__FILE__}"
#end

我注意到它是空的，但是教程的步骤不需要任何更改。

您的错误表明框架无法加载文件

“/Users/kelvinyu/rails\u projects/sample\u app/signup with invalid information”

，该文件显然不是

“spec/requests/user\u pages\u spec.rb”

。尝试将所有内容都放在一行中，而不使用

\>

（此斜线角括号仅表示在Michael Hartl键入教程时，可能有一个换行符

---

另外，要注意互换使用。这会使您编写更清晰的规范。这并没有什么神奇之处。RSpec的源代码显示，

context

只是

descripe

的另一个名称。但是当您编写同时使用这两种规范的规范时，含义会更清晰。

尝试在不使用“\”的情况下运行RSpec，即只需键入$bundle exec RSpec spec/requests/user_pages_spec.rb>-e“使用无效信息注册”你说你在共享你的

spec\u helper

文件，但那不是你共享的。你能共享你的

spec\u helper

文件吗？@SachinSingh-我尝试按照你的建议运行rspec，但同样的错误消息显示。@PeterAlfvin我已经添加了spec helper，但它是空的。你认为这是错误的根源吗？什么你想在rspec命令行中处理

\>

吗？谢谢你的解释。这个解决方案奏效了，似乎

\>

是一个换行符。正确的命令应该是

bundle exec rspec spec/requests/user\u pages\u spec.rb\

，我想你仍然误解了这个情况。the“-e”指定要运行的测试。如果完全忽略参数，则运行的是整个文件。另外，您是否介意指向教程中包含

\>

的任何内容？@PeterAlfvin！当然！就在图7.17的后面。因此，在我运行rspec之后，如上所述，作为

bundle exec rspec spec/requests/user\u pages\u spec.rb\

，

显示，我可以通过键入

-e“使用无效信息注册”

@PeterAlfvin来运行测试的其余部分，这就是我看到

\>

正在使用的地方，但实际上我将该部分误读为一个命令行。
