Ruby on rails 使用rspec时获取错误

我正在做一个关于rspec的教程，每当我试图通过终端执行rake测试或手动运行rspec时，总是会出错。以下是我得到的：

谁能告诉我我做错了什么

编辑：有关我按要求所做工作的更多信息：

我跟随教程。在上面的代码中，我尝试在hello_spec.rb文件中的hello.rb文件上运行测试，该文件中包含“require hello”代码

您给RSpec的spec文件路径错误

当前工作目录是

00\u hello

mes-mbp:00_hello Me$ rspec 00_hello/hello_spec.rb

将导致RSpec查找

00\u hello\00\u hello\hello\u spec.rb

如果运行了

rspec--init

可能有一个

.rspec

文件，如果该文件包含以下行，则需要

spec\u helper.rb

：

--require spec_helper

编写规范时最常见的做法是将规范放置在名为

spec

的目录中。这样，您就可以按运行所有项目规范

 $ rspec specs

补充： 这是gems和其他ruby项目非常常见的结构：

lib/
   hello.rb
spec/
   spec_helper.rb
   hello_spec.rb

它非常常见，RSpec会自动将

/lib

和

/spec

目录添加到加载路径

因此，您可以：

# spec/hello_spec.rb
require 'spec_helper'
require 'lib/hello' # instead of a relative path! Wehoo.

RSpec.describe Hello do
  # ...
end

你能发布一些关于你正在做什么的更多信息吗？

touch spec\u helper.rb

我根本看不到

spec\u helper

文件。这看起来甚至不像rails应用程序。也许是西纳特拉？您还需要在项目的根目录下运行

rspec--init

。这将创建类似于

spec\u helper

的文件。更多信息。那些教程已经非常过时了-我推荐类似的东西。您肯定不想开始使用RSpec2，然后必须学习新的RSpec3语法。
