我试图通过阅读教程将 bootstrap 添加到我的Rails应用程序中，但出现以下错误。请说明发生了什么，并请编辑我的代码以显示如何解决。而且，您会引用在Rails上获得任何改进的任何资源，将不胜感激。
P.s.我才刚开始谢谢您的阅读。 :D

最佳答案

您是否将以下内容添加到Gemfile中并在其后运行bundle install？

gem 'bootstrap-sass', '~> 3.3.6'
gem 'sass-rails', '>= 3.2'
rails使用 sprockets框架来预处理 Assets ，其中包括样式表，javascript和图像。在预处理期间，当遇到 @import "bootstrap";时，它将遍历 Assets 路径目录以找到导入的引导目录或文件。根据您遇到的错误，看来 sprockets引擎无法找到 bootstrap。

确保已将 bootstrap-sass包含在 Gemfile中，然后运行 bundle install以查看错误是否消失。
