包括在Webpack生產中不起作用的node_modules css文件

Question

我的代碼包括來自node_modules一些CSS，例如

import React, { PropTypes } from 'react';
import Slider from 'rc-slider';
import 'rc-slider/assets/index.css';
import styles from '../css/SeekBar.css';

我正在從node_module rc-slider導入css文件rc-slider/assets/index.css 。 這可以在我的Webpack配置中進行開發

  {
    test: /\.css$/,
    use: ['style-loader', 'css-loader'],
    include: [path.join(__dirname, '..', 'node_modules')],
  },

但是在我的生產配置中，這不起作用

{
    test: /\.css$/,
    use: ExtractTextPlugin.extract({
      fallback: 'style-loader',
      use: [
        {
          loader: 'css-loader',
          options: {
            module: true,
            localIdentName: '[path][name]__[local]___[hash:base64:5]',
          },
        },
        {
          loader: 'postcss-loader',
          options: { plugins: postCSSConfig },
        },
      ],
    }),
  },
  {
    test: /\.css$/,
    use: ['style-loader', 'css-loader'],
    include: [path.join(__dirname, '..', 'node_modules')],
  },

錯誤如下

   Child extract-text-webpack-plugin:
           [0] ../~/css-loader?{"module":true,"localIdentName":"[path][name]__[local]___[hash:base64:5]"}!../~/postcss-loader?{}!../~/style-loader!../~/css-loader!../~/rc-slider/assets/index.css 988 bytes {0} [built] [failed] [1 error]

        ERROR in ../~/css-loader?{"module":true,"localIdentName":"[path][name]__[local]___[hash:base64:5]"}!../~/postcss-loader?{}!../~/style-loader!../~/css-loader!../~/rc-slider/assets/index.css
        Module build failed: Unknown word (5:1)

          3 | // load the styles
          4 | var content = require("!!./../../css-loader/index.js!./index.css");
        > 5 | if(typeof content === 'string') content = [[module.id, content, '']];
            | ^
          6 | // add the styles to the DOM
          7 | var update = require("!./../../style-loader/addStyles.js")(content, {});

如果我刪除

 {
    test: /\.css$/,
    use: ['style-loader', 'css-loader'],
    include: [path.join(__dirname, '..', 'node_modules')],
  },

從生產的Webpack配置中沒有任何錯誤，但是樣式並未從rc-slider/assets/index.css 。

通過做解決

{
    test: /\.css$/,
    use: ExtractTextPlugin.extract({
      fallback: 'style-loader',
      use: [
        {
          loader: 'css-loader',
          options: {
            modules: true,
            localIdentName: '[path][name]__[local]___[hash:base64:5]',
          },
        },
        {
          loader: 'postcss-loader',
          options: { plugins: postCSSConfig },
        },
      ],
    }),
    include: [path.join(__dirname, '..', 'app')],
    exclude: [path.join(__dirname, '..', 'node_modules')],
  },
  {
    test: /\.css$/,
    use: ExtractTextPlugin.extract({
      fallback: 'style-loader',
      use: ['css-loader'],
    }),
    include: [path.join(__dirname, '..', 'node_modules')],
    exclude: [path.join(__dirname, '..', 'app')],
  },
