Question

我正在与朋友一起练习练习14，这是一些非常简单的字符串插值和用户输入抓取。我的代码如下所示：

if (revision == null)
        {
            assessment = _hazardAssessmentService.CustomQuery().Where(x => x.LaboratoryId == selectedLab.Id).OrderByDescending(x => x.Revision).FirstOrDefault();
        }
        else
        {
            int rev = (int) revision;
            assessment = _hazardAssessmentService.CustomQuery().FirstOrDefault(x => x.LaboratoryId == selectedLab.Id && x.Revision == rev);
        }

应该很简单，但我发现在user_name = ARGV.first prompt = '> ' puts "Hi #{user_name}." puts "I'd like to ask you a few questions." puts "Do you like me #{user_name}? ", prompt likes = $stdin.gets.chomp puts = "Where do you live #{user_name}? ", prompt lives = $stdin.gets.chomp puts "What kind of computer do you have? ", prompt computer = $stdin.gets.chomp puts """ Alright, so you said #{likes} about liking me. You live in #{lives}. Not sure where that is. And you have a #{computer} computer. Nice. """行之后，屏幕上没有显示提示“你住在哪里”的下一行，likes=提示输入。也就是说，在进入“喜欢”后立即跳转到“行”提示，而不显示之前的提示输出！从lives=开始的下一个提示按预期工作。

我正在使用ruby 2.1.2，但2.2.3上出现了相同的行为，并且在线REPL here

为什么会这样？

在第8行上有一个 = 。删除它应该可以解决问题。
