Question

错误：

语法错误，意外的tIDENTIFIER，期待输入结束的结束继续==＆＃34; N＆＃34;

我检查了所有代码，但我仍然没有得到它。

我应该在while continue == "N"之后添加结束代码吗？

  begin 
      puts "|===============================================|" 
      puts "|Welcome to Rock Paper Scissors!!!              |"
      puts "|===============================================|"

      begin 
        puts "please choose one of the following: R / P / S"
        user_input = gets.chomp.upcase
      end while !["R", "P", "S"].include?(user_input) 


      com_input = ["R", "P", "S"].sample

      puts "You:#{user_input} Com:#{com_input}"

      if user_input = "R" && com_input = "S" || user_input = "S" && com_input = "P" || user_input = "P" && com_input = "R"
        puts "Result:You win"  
      elsif com_input = "R" && user_input = "S" || com_input = "S" && user_input = "P" || com_input = "P" && user_input = "R"
        puts "Result:You lose"  
      else
        puts "Result:Draw"  
      end

      begin
        puts "Play Again?: Y / N"
        continue = gets.chomp.upcase
      end while !["Y", "N"].include?(continue)

    end whlie continue == "N"
    puts "Good Bye! Thanks for playing!"

Answer 1

更改whlie的{{1}}。

此外while正在检查while是否继续，我认为必须N。

如果您需要，可以减少begin ... end while continue == 'Y' puts "Good Bye! Thanks for playing!"和user输入验证，并应用一些DRY：
