请帮助

引导sass不再与Rails 3兼容。与Rails 3.2兼容的引导sass的最新版本是v3.1.1.0

导致此错误的代码在哪里？感谢Blip的关注。请忽略它，它现在已经修好了。这是引导式sass版本问题。如果现在问题解决了，请发布问题的答案或删除问题15人投票支持此问题的答案。这怎么没用？哦，我刚刚复制了它。这就是我来这里的原因。而且，不知道如何“改进”这个问题。这是对的，这不是真的。gempec没有指定rails版本要求，changelog也没有提到放弃支持。这将需要一个大版本。有趣的是，我们在生产中使用3.3.5.1和Rails 3.2.x已经有一段时间了。这对我来说很有吸引力。@naiyyar是对的，3.1.1.0是与3.2兼容的最新版本，请参见此处
