我一直在尝试按照documentation 将引导框架连接到我的项目，但由于某种原因我无法设置它。为什么会这样？

assets/stylesheets/application.scss

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.

我已经安装了 bootstrap-sass 3.3.5.1、sass-rails 5.0.3。

有什么帮助吗？

【问题讨论】：

尝试这样，而不是将这个 assets/stylesheets/application.scss 重命名为 assets/stylesheets/application.css.scss

标签： ruby-on-rails twitter-bootstrap ruby-on-rails-4

【解决方案1】：

阅读 bootstrap-sass gem 的说明并遵循他们的约定https://github.com/twbs/bootstrap-sass。

Import Bootstrap styles in app/assets/stylesheets/application.scss:

// "bootstrap-sprockets" must be imported before "bootstrap" and "bootstrap/variables"
@import "bootstrap-sprockets";
@import "bootstrap";
