javascript - [webpack2]样式未加载(.css/.less)

Question

我目前正在开发一个 webpack2 + react + antd-mobile 应用程序，除了未加载的样式(.css/.less)外，一切正常。我真的找不到问题，控制台上没有打印错误。

webpack.config.js

const path = require('path');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const autoprefixer = require('autoprefixer');
const pxtorem = require('postcss-pxtorem');

// antd-mobile SVG配置方式
const svgDirs = [
  require.resolve('antd-mobile').replace(/warn\.js$/, ''),
  path.resolve(__dirname, 'src/assets/svg'),
];

module.exports = {
  devtool: 'source-map',
  context: path.join(__dirname, 'src'),
  entry: './index',
  output: {
    filename: '[hash].js',
  },
  resolve: {
    modules: ['node_modules', path.join(__dirname, 'src')],
    extensions: ['.web.js', '.js', '.json', '.less', '.css'],
  },
  module: {
    loaders: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
      },
      {
        test: /\.(css|less)$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: ['css-loader', 'postcss-loader', 'less-loader'],
        }),
      },
      {
        test: /\.html$/,
        loader: 'html-loader',
      },
      {
        test: /\.(svg)$/i,
        use: 'svg-sprite-loader',
        include: svgDirs,
      },
    ],
  },
  plugins: [
    new ExtractTextPlugin('main.css'),
    new HtmlWebpackPlugin({
      template: 'index.html',
      hash: true,
    }),
    new webpack.DefinePlugin({
      __DEV__: JSON.stringify(JSON.parse(process.env.NODE_ENV === 'development' || 'true')),
    }),
    new webpack.LoaderOptionsPlugin({
      options: {
        postcss: () => {
          return [
            pxtorem({ rootValue: 100, propWhiteList: [] }),
            autoprefixer,
          ];
        },
      },
    }),
  ],
};

我可以导入 less，但是没有加载样式，并且控制台上没有显示错误输出；

import styles from './styles/AssetItem.less';

我不知道它是否可以帮助你，但我的部分是用 webpack2 解析 css 文件

test: /\.css$/,
    use: [
      {
    loader: "style-loader"
      },
      {
        loader: "css-loader",
        options: {
          modules: false
        }
      }
    ]
  },
