在 Ruby 中没有收到输入

Question

我有一个哨兵控制循环，它似乎不接受任何输入：

response = " "
until response == "x" do
  puts"
  Xargonia
  =========
  (N)ew
  (L)oad
  (O)ptions
  (Q)uit"
  reponse = gets
  puts response

当它试图输出用户输入的内容时，它只输出用于初始化的内容。

除了语法错误，您将 gets 的值分配给 reponse 而不是 response。另外，您需要通过链接 String::chomp:

从 gets 中删除换行符

response = " "
until response == "x" do
  puts "                              # add space between gets and double-quote
  Xargonia
  =========
  (N)ew
  (L)oad
  (O)ptions
  (Q)uit"
  response = gets.chomp               # rename reponse to response; chain .chomp
  puts response
end                                   # add missing end
