webpack 没有在 Vue.js 项目中加载 SCSS

Question

我正在使用 Vue.js 和 Webpack 作为我的构建工具构建一个前端项目。我将使用 SCSS 编写我的样式，因此我通常会使用 sass-loader。然而，虽然我可以requirematerialize-css 的 SCSS 版本，但当我尝试要求我的自定义 SCSS 文件时，我收到以下错误，有人能对此有所了解吗？

ERROR in ./node_modules/css-loader!./node_modules/sass-loader/lib/loader.js!./src/main.scss
Module build failed:
  display: flex;
                ^
      Invalid CSS after "  display: flex;": expected "}", was ".header--utils: {"
      in /media/transcend/projects/wp-vue-1/src/main.scss (line 2, column 18)
 @ ./src/main.scss 4:14-116 18:2-22:4 19:20-122
 @ ./src/main.js
 @ multi (webpack)-dev-server/client?http://192.168.1.20:8080 webpack/hot/dev-server ./main

这里是main.js

import Vue from 'vue';
import VueResource from 'vue-resource';
import AppComponent from './components/app-component/app-component';

require('materialize-css/sass/materialize.scss');
require('./main.scss');

Vue.use(VueResource);

// eslint-disable-next-line no-new
new Vue({
  el: '#app',
  components: {
    'app-component': AppComponent,
  },
});

main.scss.

.header {
  display: flex;

  .header--utils: {
    justify-content: flex-end;
  }

  .header--utils--login {
    align-self: flex-end;
  }
}

和我的 webpack 配置：

const path = require('path');
const webpack = require('webpack');

const APP = path.resolve(__dirname, './src');
const sassOpt = {
  sourceMap: true,
  includePaths: [
    path.resolve(APP, '**/*.scss'),
  ],
};

module.exports = {
  context: APP,
  entry: './main',
  output: {
    path: APP,
    filename: './bundle.js',
  },
  devtool: 'inline-source-map',
  devServer: {
    contentBase: './src',
    host: '0.0.0.0',
    public: '192.168.1.20:8080',
    hot: true,
  },
  module: {
    rules: [
      {
        test: /\.html$/,
        loader: 'raw-loader',
      },
      {
        enforce: 'pre',
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'eslint-loader',
        options: {
          quiet: true,
        },
      },
      {
        test: /\.js$/,
        exclude: '/node_modules',
        loader: 'babel-loader',
        query: {
          presets: ['es2015'],
        },
      },
      {
        test: /\.scss$/,
        use: [
          {
            loader: 'style-loader',
          },
          {
            loader: 'css-loader',
            options: {
              sourceMap: true,
            },
          },
          {
            loader: 'sass-loader',
            options: sassOpt,
          },
        ],
      },
      {
        test: /\.(eot|woff|woff2|ttf|svg|png|jpg)$/,
        loader: 'url-loader?limit=30000&name=[name]-[hash].[ext]',
      },
    ],
  },
  resolve: {
    alias: {
      vue: 'vue/dist/vue.js',
    },
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
  ],
};

还有package.json

Answer 1

发现问题是自己造成的。我在 .scss 文件中的元素选择器之后添加了一个冒号：

  .header--utils: {

我删除了冒号，它工作正常：-/

Answer 2

我猜你必须使用新的 webpack 语法。使用规则参数为here
