Question

Webpack和Bootstrap 4 mixins和功能出现问题。

sass | css加载程序：

{
    test: /\.(sa|sc|c)ss$/,
    use: [
        // fallback to style-loader in development
        // which creates style nodes from JS strings (IE: imports)
        process.env.NODE_ENV === 'development' ? 'style-loader' : MiniCssExtractPlugin.loader,
        {
            loader: 'css-loader',
            options: {
                sourceMap: true
            }
        },
        {
            loader: 'sass-loader',
            options: {
                sourceMap: true,
                includePaths: ['node_modules']
            }
        }
    ]
}

导入为：

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/mixins";
@import "bootstrap/scss/print";
@import "bootstrap/scss/reboot";
@import "bootstrap/scss/type";
@import "bootstrap/scss/images";
@import "bootstrap/scss/code";
@import "bootstrap/scss/grid";
@import "bootstrap/scss/tables";
@import "bootstrap/scss/forms";
@import "bootstrap/scss/buttons";
@import "bootstrap/scss/transitions";
@import "bootstrap/scss/dropdown";
@import "bootstrap/scss/button-group";
@import "bootstrap/scss/input-group";
@import "bootstrap/scss/custom-forms";
@import "bootstrap/scss/nav";
@import "bootstrap/scss/navbar";
@import "bootstrap/scss/card";
@import "bootstrap/scss/breadcrumb";
@import "bootstrap/scss/pagination";
@import "bootstrap/scss/badge";
@import "bootstrap/scss/jumbotron";
@import "bootstrap/scss/alert";
@import "bootstrap/scss/progress";
@import "bootstrap/scss/media";
@import "bootstrap/scss/list-group";
@import "bootstrap/scss/close";
@import "bootstrap/scss/modal";
@import "bootstrap/scss/tooltip";
@import "bootstrap/scss/popover";
@import "bootstrap/scss/carousel";
@import "bootstrap/scss/utilities";

除了mixin和函数，一切似乎都很好用。

例如，color: color("purple");可以很好地工作并放置适当的颜色，但是简单的<span className="badge badge-green ml-2">badge here</span>会加载徽章的基本样式，而不会加载绿色的颜色变体。

没有任何类型的错误，所以我不确定发生了什么。

您是否在$theme-colors引导变量中定义了颜色变体“绿色”？

默认情况下，只有以下选项（从bootstrap/_variables.scss复制）：

$theme-colors: () !default;
// stylelint-disable-next-line scss/dollar-variable-default
$theme-colors: map-merge(
  (
    "primary":    $primary,
    "secondary":  $secondary,
    "success":    $success,
    "info":       $info,
    "warning":    $warning,
    "danger":     $danger,
    "light":      $light,
    "dark":       $dark
  ),
  $theme-colors
);

$theme-color变量被所有组件用于这样的颜色修改器（以bootstrap/_badge.scss为例，以徽章组件为例）：

@each $color, $value in $theme-colors {
  .badge-#{$color} {
    @include badge-variant($value);
  }
}

因此，如果您要使用颜色变体“绿色”，则必须先将其注册到$theme-colors变量中，如下所示（无论您覆盖默认的引导变量）：

$theme-colors: (
  "green": #00ff00
);

更多信息可以通过引导程序本身在徽章组件的文档（https://getbootstrap.com/docs/4.1/components/badge/）和主题颜色的文档（https://getbootstrap.com/docs/4.1/getting-started/theming/#theme-colors）中找到。
