Question

此时，我只是尝试使用命令行从文件中显示一些基本行。

继承我的模块：

require "reverb_exercise/version"

module ReverbExercise
  class Parser
    attr_accessor :records

    def parse_file(file)
      @lines = []
      File.open(file, "r") do |file|
        file.each_line do |line|
          @lines << line
        end
      end
      @lines
    end

    def build_records
      @records = []
      @lines.each do |line|
        @records << Record.new(*line.split(", "))
      end
      @records
    end
  end

  class Record
    attr_accessor :first_name, :last_name, :gender, :color, :birthdate

    def initialize(first_name, last_name, gender, color, birthdate)
      @first_name = first_name
      @last_name = last_name
      @gender = gender
      @color = color
      @birthdate = birthdate
    end
  end
end

这是bin文件夹：

#!/usr/bin/env ruby

require 'reverb_exercise'

puts ReverbExercise::Parser.new.parse_file("comma.txt")

当我在终端中运行reverb时，收到以下undefined local variable or method错误：

Users / yedidyaweiner / .rbenv / versions / 2.1.2 / lib / ruby / gems / 2.1.0 / gems / reverb_exercise-0.0.1 / lib / reverb_exercise.rb:10:in block (2 levels) in parse_file': undefined local variable or method lines' for＃（NameError）

我错过了什么？

试图在终端中运行小程序，接收错误
