Question

我正在做一个关于rspec的教程，每当我尝试执行rake测试或通过终端手动运行rspec时都会遇到错误。这是我得到的：

mes-mbp:00_hello Me$ ls
hello.rb    hello_spec.rb   index.html
mes-mbp:00_hello Me$ rspec 00_hello/hello_spec.rb
/Users/Me/.rvm/rubies/ruby-2.2.0/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- spec_helper (LoadError)

    from /Users/Me/.rvm/gems/ruby-2.2.0/bin/ruby_executable_hooks:15:in `<main>'

谁能告诉我我做错了什么？

编辑：有关我正在按要求执行的操作的更多信息：我正在关注this教程。在上面的代码中，我试图在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。

您正在为RSpec提供指定文件的错误路径。

当前工作目录为00_hello。

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

将导致RSpec查找00_hello\00_hello\hello_spec.rb。

如果您运行rspec --init，则可能有.rspec个文件，如果该文件包含该行，则该文件需要spec_helper.rb：

--require spec_helper

编写规范时最常见的做法是将规范放在名为spec的目录中。这样您就可以通过

运行所有项目规范

 $ rspec specs

对于宝石和其他红宝石项目来说，这是一个非常常见的结构：

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

它很常见，RSpec会自动将/lib和/spec目录添加到加载路径。

所以你可以这样做：

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

RSpec.describe Hello do
  # ...
end

使用rspec时出错
