Npm 引导程序5的网页包缓慢构建

当我在我的项目中导入引导SCS时，Webpack构建非常缓慢。它根据每一次代码更改构建所有引导依赖项。因此，我必须等待5-6秒，每节省文件。有什么方法可以缩短构建时间？可能只在bootsrap-variables.scss文件更改时构建bootsrap

以下是我的网页包配置：

const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const OptimizeCSSAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const TerserJSPlugin = require('terser-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const sass = require('sass');
const path = require('path');

module.exports = (env, argv) => {
    return {
        entry: {
            bundle: ['./src/index.js', './src/index.scss'],
            admin: ['./src/admin.js', './src/admin.scss'],
            print: './src/print.scss',
        },
        output: {
            path: path.resolve(process.cwd(), 'dist'),
            filename: '[name].js',
        },
        optimization: {
            minimizer: [
                new TerserJSPlugin(),
                new OptimizeCSSAssetsPlugin({
                    cssProcessorOptions: {
                        map: {
                            inline: false,
                            annotation: true,
                        },
                    },
                }),
            ],
        },
        plugins: [
            new CleanWebpackPlugin({
                cleanAfterEveryBuildPatterns: ['!fonts/**/*'],
                output: {
                    path: path.resolve(process.cwd(), 'dist'),
                },
            }),
        ],
