尝试在 Heroku 上通过 bootstrap-sass 导入 bootstrap 但出现错误

我有一个 Rails 应用程序，并尝试按照此处的说明使用 Bootstrap-sass 在 Heroku 上导入 Bootstrap：https://github.com/thomas-mcdonald/bootstrap-sass https://github.com/thomas-mcdonald/bootstrap-sass

在我的 application.css 中，我有：

@import "bootstrap";
/*
 * 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 vendor/assets/stylesheets of plugins, if any, 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 top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 */

@import "overrides.css.scss";

但当我收到以下错误git push heroku master.

我究竟做错了什么？

已经有一段时间了，不确定这是否仍然相关。看来您的 application.css 应该命名为 application.css.scss ，以便 Sass 处理它。否则普通的 CSS @import 指令将无法识别 Sass Bootstrap。
