“无法自动加载常量”使用rspec而不是rails

app/workers/station/http.rb

module Worker 
    module Station 
    class HTTP 
     # ... 
    end 
    end 
end

这是我的规格文件。

spec/workers/station/http_spec.rb

describe Worker::Station::HTTP do 
    it "should do something" do 
    end 
end

现在的问题是使用RSpec的运行规范文件时，我发现了以下错误。

rspec spec/workers/station/http_spec.rb

/Users/linus/.rvm/gems/[email protected]/gems/activesupport-4.0.4/lib/active_support/dependencies.rb:464:in `load_missing_constant': Unable to autoload constant Station::HTTP, expected app/workers/station/http.rb to define it (LoadError)

    from /Users/linus/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'

奇怪的是，everyting在控制台工作。

$ rails c [1] pry(main)> Worker::Station::HTTP => Worker::Station::HTTP

为什么使用这个RSpec的发生，而不是在铁轨和我将如何解决？

我使用

轨（4.0.4）
rspec的（2.14.1）

我收到了同样的错误。你有没有想过如何解决这个问题？ –

由于rspec没有自动加载app/workers路径，因为它不是标准导轨布局，您可以将autoload行添加到spec_helper或直接在规范中要求该文件！ – jfornoff

@jfornoff请插入您的评论作为答案。这将有助于其他人员遇到这个问题。谢谢您的帮助！ – avital

由于jfornoff建议你可以添加一个需要声明的规范与语句像下面这样：

require "app/workers/station/http"

但是，如果你使用的是Spring Rails应用程序预加载和上面没有解决该问题，你也可以检查是否需要重新启动Spring。您可以测试，而不使用Spring如下运行规范：

bundle exec rspec spec/workers/station/http_spec.rb

......或者......

spring stop # or bin/spring stop 
rspec spec/workers/station/http_spec.rb
