嗨，对 Rails 很陌生，目前正在处理 rake 文件中的任务定义。这是我的代码

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 SOutput

   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，上面的错误我没有关于这个错误的大图景。谁能指导我？
