Question

我必须实施Rock，Paper，Scissors游戏的一小部分作为作业。这是我的代码：

class RockPaperScissors

  # Exceptions this class can raise:
  class NoSuchStrategyError < StandardError ; end

  def self.winner(player1, player2)
    # YOUR CODE HERE

    puts "player1 = " + player1[1]
    if (player1[1] || player2[1] != 'R') || (player1[1] || player[2] != 'P') || (player1[1] || player2[1] != 'S')
      raise NoSuchStrategyError.new("Strategy must be one of 'R','S','P'")
    else
      if player1[1] == player2[1]
        return player1
      elsif (player1[1] == 'R' && player2[1] == 'P') || (player1[1] == 'P' && player2[1] == 'S') || (player1[1] == 'S' && player2[1] == 'R')
        return player2
      else 
        return player1
      end
    end
  end

  def self.tournament_winner(tournament)
    # YOUR CODE HERE
  end

end

我正在使用rspec测试代码，它在以下两种情况下都会中断。我假设它与我检查的位置有关，以确保输入有效，即使输入有效，无论出于何种原因，我在行if (player1[1] || player2[1] != 'R') || (player1[1] || player[2] != 'P') || (player1[1] || player2[1] != 'S')的方式使输入失败在每个案例上。如何修复该行，以便在输入有效时，它不会引发错误？

Failures:

  1) RockPaperScissors game rock breaks scissors [10 points]
     Failure/Error: raise NoSuchStrategyError.new("Strategy must be one of 'R','S','P'")

     RockPaperScissors::NoSuchStrategyError:
       Strategy must be one of 'R','S','P'
     # ./lib/rock_paper_scissors.rb:11:in `winner'
     # ./spec/rock_paper_scissors_spec.rb:10:in `block (3 levels) in <top (required)>'

编辑：player1和player2是格式为[“playername”，“move”]的数组，其中R，S或P为摇滚，剪刀或纸张
