如果满足给定条件，则结束ruby程序

Question

基本上，如果满足某个条件，我只是试图阻止程序运行其余的行。

unless raw_information.first
  puts "No results were returned for that query"
  break
end

然而，在程序运行之前我得到了这个错误：

  

无效的休息   编译错误（SyntaxError）

这样做的正确方法是什么？

Answer 1

abort("No results were returned for that query") unless condition

或

unless condition
  abort("No results were returned for that query")
end
