Webpack sass-loader无效的CSS

Question

运行我的构建时,我收到此错误.

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

我也尝试使用vanilla JS webpack配置并获得相同的错误,因此它不是TypeScript配置.还尝试了extract-text-webpack-plugin但得到了同样的错误.实际的应用程序工作正常,但显然没有CSS.这是配置.

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

这是主sass文件的片段.

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

哪个是在主app文件中导入的:

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

我认为错误是因为你url-loader以Sass某种方式使用文件.拆分webpack.config规则,(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",
  }]
}
