我按照此处编写的说明进行操作 - https://github.com/twbs/bootstrap-sass 但引导程序似乎无法正常工作。我安装了所需的 gem，更新了 github 文档中编写的文件，然后在我的 application_layout 中，

它打破了布局，网格一个接一个。

我认为您的引导网格无法在浏览器中运行的原因是您的屏幕分辨率可能太小。由于它很小，它需要 col-sm-4 类，并且您还忘记了关闭容器。我发布了一个小提琴https://jsfiddle.net/rvega20/pogfb4w9/

同样如前所述，为了使用 bootstrap-sass，必须使用称为“SCSS”的主要语法（从 Sass 3 开始）。所以直接从引导文档——> 确保文件具有 .scss 扩展名（或 .sass 用于 Sass 语法）。如果您刚刚生成了一个新的 Rails 应用程序，它可能会附带一个 .css 文件。如果这个文件存在，它将被提供而不是 Sass，所以重命名它：

$ mv app/assets/stylesheets/application.css app/assets/stylesheets/application.scss

然后，从文件中删除所有//= requireand//= require_tree语句。相反，使用 @import 导入 Sass 文件。

不要//= require在 Sass 中使用，否则您的其他样式表将无法访问 Bootstrap 混入或变量。

在 app/assets/javascripts/application.js 中需要 Bootstrap Javascript：

//= require jquery
//= require bootstrap-sprockets

bootstrap-sprockets 和 bootstrap 不应同时包含在 application.js 中。

bootstrap-sprockets 提供单独的 Bootstrap Javascript 文件（例如，alert.js 或 dropdown.js），而 bootstrap 提供包含所有 Bootstrap Javascript 的串联文件。

检查您的application.css文件 - 它必须被删除，而不是它，您必须拥有application.css.scss包含内容的文件：

@import "bootstrap-sprockets"; @import "bootstrap";

我会尝试猜测您的问题是什么，但是您没有提供必要的上下文代码，因此任何人都无法确定地回答您。

我猜你没有嵌套在行 div 中。
