我尝试生成一个控制器,但它给了我这个错误.我无法在我的文件中找到导致此错误的位置,因此非常感谢帮助.我正在运行Ruby'2.0.0'和rails'4.2.0.beta2',如果这有帮助的话.请帮忙!谢谢
我不明白为什么这篇文章被标记为重复.我的问题与其他问题无关.另外,我想知道如何解决它,据我所知,我甚至没有看到修复该错误.请帮忙!

我需要这个检查,看看是否有零,所以我可以添加整数,如果有,如果没有零值,然后停止游戏.
var smallestArr = [Int?](count: 25, repeatedValue: nil)
if smallestArr.contains(nil){
//add ints until it doesn't contain anymore nil
}else{
//end game
