答案 0 :(得分：0)
您在初始化方法中发生的所有错误，正如您在此处列出的那样。在每种情况下，错误都是相同的，“错误的参数数量（0表示1）”。
这意味着您需要了解如何构建Fiction_Generator对象。在这种情况下，initialize方法要求您传入IO对象。所以不要只使用
fict_gen = Fiction_Generator.new
您需要在新方法中传递IO对象
fict_gen = Fiction_Generator.new(#IO object here)
编辑：
所以你从上面的代码中删除了构造函数方法，现在我不知道你的初始化方法是什么样的，所以我写的内容可能不再适用了。但是，错误仍然在初始化方法中，因此请将精力集中在那里。
