Ruby on rails 雷克流产了！未初始化常量<；类名>；

嗨，嗯，对rails来说很新，目前正在rake文件中进行任务定义。这是我的密码

test_task.rake

namespace :test_name_space do
  namespace :to do
    task :my_task do
      p "========================="
      sample_out_put = SOutput.new
      sample_out_put.createfileoutput
    end
  end
end

在我的肚子里

   class SOutput



      def createfileoutput
        current_time = Time.new
        puts "====================================="
        puts "This is a scheduled file output"
        puts "====================================="
        File.open("/home/kalanamith/Desktop/out.txt", "a+") do |file|
        p current_time.inspect.to_s
        file.write("This is a sample test")
        file.write(current_time.inspect.to_s)
        end
      end


    fileoutput = SOutput.new
    fileoutput.createfileoutput
end

当我运行

rake test_name_space:to:my_task
"========================="
rake aborted!
uninitialized constant SOutput

嗯，这是一个错误 我对这个错误不太了解。有人能指引我吗

仍然收到相同的错误**调用测试名称空间：到：我的任务（第一次）*调用环境（第一次）**执行环境**执行测试名称空间：到：我的任务”====================================rake中止！未初始化常量soutput此选项不提供问题的答案。若要评论或要求作者澄清，请在其帖子下方留下评论。@eugen ah。。好的，这是因为我确信这就是问题所在，因为我以前也遇到过这个问题。@Kalanamith您可以在rails c中使用SOutput吗？也许它装得不好？如果是，那么您需要将其移动到standarrails加载目录（如app）或要求它firstOaky。我试试看：）谢谢你的soutput班在哪里？
