gem中的错误：未初始化的常量项

Question

所以我想将一个方法委托给一个单独的类，并为gem提供以下主文件：

def record(self):
    for i in range(100000000):
        t="allllaaaa"
    self.textEdit.setPlaceholderText("waiting ... ")


def threadRecord(self):
    self.textEdit.setPlaceholderText("speak now ")
    thread = Thread(target = self.record)
    thread.start()
    thread.join()

require "content/version" require "content/models/item" require "content/models/category" require "content/transformer" require "content/service" require "content/presenter" require 'active_support/core_ext/module/delegation' module Content extend self extend Forwardable def_delegator :Item, :find, :find def_delegator :Item, :find_multiple, :find_multiple def_delegator :Category, :find, :find_category end 定义如下：

require "content/models/item"

关于我哪里出错的任何想法？
