无法让 twitter-bootstrap-rails mixin 工作

Question

我在 app/assets/stylesheets/scaffolds.scss 中有以下 CSS 的片段：

.input-container {
    @include make-lg-column(3);
}

加载页面时出现以下错误：

Undefined mixin 'make-lg-column'.

我在 app/assets/stylesheets/bootstrap_and_overrides.css.less 中有以下几行：

@import "twitter/bootstrap/variables.less";
@import "twitter/bootstrap/mixins.less";

这是我在 app/assets/stylesheets/application.css 中的内容：

/*
 * 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, 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 other CSS/SCSS
 * files in this directory. Styles in this file should be added after the last require_* statement.
 * It is generally better to create a new file per style scope.
 *
 *= require bootstrap_and_overrides
 *= require_tree .
 *= require_self
 */

如有任何关于如何解决此问题的建议，我们将不胜感激。

您似乎在 LESS in a SCSS file. I'd suggest to try the SASS 版本中使用 bootstrap。

# Gemfile
gem 'bootstrap-sass', '~> 3.3.7'
gem 'sass-rails', '>= 3.2'

# SCSS file
@import "bootstrap-sprockets";
@import "bootstrap";
