Webpack 网页包sass加载程序无效CSS

每当运行构建时，我都会遇到此错误

Invalid CSS after "module.exports": expected "{", was '= "data:text/x-scss'

我也尝试过使用一个普通的JS网页包配置，但得到了相同的错误，所以它不是TypeScript配置。也尝试提取文本网页包插件，但得到相同的错误。实际的应用程序运行良好，但显然没有CSS。这里是配置

import * as path from 'path';
import * as webpack from 'webpack'

const config: webpack.Configuration = {
    entry: {
        app: ['./js/main.ts']
    },
    output: {
        path: path.resolve(__dirname, './dist/js'),
        filename: '[name].js'
    },
    module: {
        rules:[
            {
                test: /\.html$/,
                loader: 'ngtemplate-loader?prefix=/&module=app&relativeTo=' + (path.resolve(__dirname, './js/app')) + '/!html-loader'
            },
            {
                test: /\.ts$/,
                loader: 'awesome-typescript-loader'
            },
            {
                test: /\.(sass|scss|ttf|svg|woff)$/,
                use: [{
                    loader: "style-loader"
                }, {
                    loader: "css-loader"
                }, {
                    loader: "sass-loader",
                }, {
                    loader: "url-loader"
                }]
            }
        ]
    }
}

export default config

下面是主sass文件的片段

@import "utilities/variables";
@import "utilities/animations";
@import "utilities/helpers";

在主应用程序文件中导入的，包含：

import '../sass/sass.scss';

---

我认为错误是因为您不知何故对

Sass

文件使用了

url加载程序。将webpack.config规则拆分为
（sass | scss | ttf | svg | woff）
，如下所示：

{
  test: /\.(ttf|svg|woff)$/,
  use: [{
    loader: "url-loader"
  }]
},
{
  test: /\.(sass|scss)$/,
  use: [{
    loader: "style-loader"
  }, {
    loader: "css-loader"
  }, {
    loader: "sass-loader",
  }]
}
