将 Bootstrap 3 CSS 导入 Angular 2+ 并将 SASS 作为 CSS

Question

我需要覆盖 Bootstrap (3.3.7) CSS 中的某些内容，因此我需要在所有其他样式之前加载 Bootstrap 才能做到这一点。我知道这样做的方法是将它导入到文档顶部我的应用程序的主 styles.sass 中。但是当我通过以下方式执行此操作时：

@import ./bootstrap.css

我得到：

ERROR in ./~/css-loader!./src/bootstrap.css

那没有用，因为我没有将字体带入项目。

这让我觉得一定有更合适的安装方法 bootstrap。

然后我找到 bootstrap-sass，并使用 npm install bootstrap-sass --save 将其导入，然后将其导入 styles.sass：

@import ../node_modules/bootstrap-sass/assets/stylesheets/_bootstrap.scss

然后我得到：

ERROR in ./~/css-loader!./~/postcss-loader!./~/sass-loader!./src/styles.sass

难道不应该有一个干净的方法来做到这一点吗？

Answer 1

我假设你正在使用 webpack，所以你应该看看这个线程：

Bootstrap.sass and Webpack

Answer 2

我开始学习 Bootstrap 因为 Sass 有一个变量专门用于将它定向到字体所在的位置。如果它们是使用 npm install bootstrap-sass --save 安装的，那么您需要在 styles.sass:

的顶部使用这两行导入 bootstrap-sass

$icon-font-path: "~bootstrap-sass/assets/fonts/bootstrap/"
@import ../node_modules/bootstrap-sass/assets/stylesheets/_bootstrap.scss
