Bootstrap 4 Webpack Sass功能不起作用

Question

Webpack和Bootstrap 4 mixins和功能出現問題。

sass | css加載器：

{
    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']
            }
        }
    ]
}

導入：

@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";

一切似乎都很好，除了在mixin和函數方面。

例如， color: color("purple"); 可以正常工作，並放置適當的顏色，但是一個簡單的<span className="badge badge-green ml-2">badge here</span>會加載徽章的基本樣式，但不會加載綠色的顏色變體。

沒有任何類型的錯誤，所以我不確定發生了什么。

您是否在$theme-colors bootstrap變量中定義了顏色變體“綠色”？

默認情況下，只有以下選項（從bootstrap/_variables.scss復制）：

$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變量被所有組件用於顏色修飾符，例如bootstrap/_badge.scss使用badge組件作為示例從bootstrap/_badge.scss復制）：

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

因此，如果要使用顏色變體“綠色”，則必須首先將其注冊在$theme-colors變量中，如下所示（無論您覆蓋默認的引導變量）是什么：

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

更多信息可在該徽章組件的文檔（可以找到https://getbootstrap.com/docs/4.1/components/badge/ ）和主題顏色的文檔（ https://getbootstrap.com/docs/4.1/getting -booted / theming /＃theme-colors ）。
