带有sass-loader、MiniCssExtractPlugin和uikit的MiniCssExtractPlugin

Question

我正在尝试安装uitkit模板

• webpack 4
• sass装载机
• MiniCssExtractPlugin
• 乌伊基特

我想要实现的是，构建会自动将sass转换为css，并将生成的css注入到src/index.html中。

webpack.config.js

const HtmlWebPackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
module.exports = {
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        }
      },
      {
        test: /\.html$/,
        use: [
          {
            loader: "html-loader",
            options: { minimize: true }
          }
        ]
      },
      {
    test: /\.scss$/,
    use: [
      MiniCssExtractPlugin.loader,
      {
        loader: "css-loader",
        options: {
          modules: true,
          sourceMap: true,
          importLoader: 4
        }
      },
      "sass-loader"
    ]}
    ]
  },
  plugins: [
    new HtmlWebPackPlugin({
      template: "./src/index.html",
      filename: "./index.html"
    }),
    new MiniCssExtractPlugin({
      filename: "[name].css",
      chunkFilename: "[id].css"
    })
  ]
};

index.js

import UIkit from 'uikit';
import Icons from 'uikit/dist/js/uikit-icons';
import style from "uikit/src/scss/uikit.scss"
UIkit.use(Icons);

不幸的是，的构建失败

ERROR in ./node_modules/uikit/src/scss/uikit.scss (./node_modules/css-loader??ref--6-1!./node_modules/sass-loader/lib/loader.js!./node_modules/uikit/src/scss/uikit.scss)
Module build failed (from ./node_modules/sass-loader/lib/loader.js):
$inverse-base-color: $inverse-global-color !default;
Undefined variable: "$inverse-global-color".
in new_proj/node_modules/uikit/src/scss/components/base.scss (line 607, column 49)

如果有人能解释我做错了什么，为什么sass加载器找不到变量$逆全局颜色，我会很感激。

我找到了答案。它是这样运作的：

index.js

...
import style from "./main.scss"
...

main.scss

// 1. Your custom variables and variable overwrites.
$global-link-color: #DA7D02;

// 2. Import default variables and available mixins.
@import "uikit/src/scss/variables-theme.scss";
@import "uikit/src/scss/mixins-theme.scss";

// 3. Your custom mixin overwrites.
@mixin hook-card() { color: #000; }

// 4. Import UIkit.
@import "uikit/src/scss/uikit-theme.scss";
