webpack 的文件加载器不会将 src 文件夹图像文件移动到 dist 文件夹

Question

{
        test: /\.(png|jpg|gif)$/,
        loader: 'file-loader?name=img/img-[hash:6].[ext]',
      },

我将此配置添加到中以通过将上述规则添加到中webpack.config.js来使用file-loader

module: {
    rules: [

部分，但没有任何图像文件移动到dist/文件夹，即使我将图像文件放入src/images/. 我是否遗漏了一些需要添加到 webpack 配置中的内容？

我正在遵循https://julienrenaux.fr/2015/03/30/introduction-to-webpack-with-practical-examples/中的示例

顺便说一句，我正在使用 webpack 2...现在有不同的方法来配置文件加载器吗？

这是整个 webpack 配置文件

const { resolve } = require('path');

const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const OpenBrowserPlugin = require('open-browser-webpack-plugin');

const config = {
  devtool: 'cheap-module-eval-source-map',

  entry: [
    'react-hot-loader/patch',
    'webpack-dev-server/client?http://localhost:8080',
    'webpack/hot/only-dev-server',
    './main.js',
    './assets/scss/main.scss',
  ],

  output: {
    filename: 'bundle.js',
    path: resolve(__dirname, 'dist'),
    publicPath: '/',
  },

  context: resolve(__dirname, 'app'),

  devServer: {
    hot: true,
    contentBase: resolve(__dirname, 'dist'),
    publicPath: '/',
  },

  module: {
    rules: [
      {
        test: /\.js$/,
        loaders: [
          'babel-loader',
        ],
        exclude: /node_modules/,
      },
      {
        test: /\.scss$/,
        exclude: /node_modules/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [
            'css-loader',
            {
              loader: 'sass-loader',
              query: {
                sourceMap: false,
              },
            },
          ],
        }),
      },
      { test: /\.(png|jpg)$/, use: 'url-loader?limit=15000' },
      { test: /\.eot(\?v=\d+.\d+.\d+)?$/, use: 'file-loader' },
      { test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/, use: 'url-loader?limit=10000&mimetype=application/font-woff' },
      { test: /\.[ot]tf(\?v=\d+.\d+.\d+)?$/, use: 'url-loader?limit=10000&mimetype=application/octet-stream' },
      { test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, use: 'url-loader?limit=10000&mimetype=image/svg+xml' },
      {
        test: /\.(png|jpg|gif)$/,
        loader: 'file-loader?name=img/img-[hash:6].[ext]',
      },
    ],
  },

  plugins: [
    new ExtractTextPlugin({ filename: 'style.css', disable: false, allChunks: true }),
    new CopyWebpackPlugin([{ from: 'vendors', to: 'vendors' }]),
    new OpenBrowserPlugin({ url: 'http://localhost:8080' }),
    new webpack.HotModuleReplacementPlugin(),
  ],
};

module.exports = config;

Answer 1

使用以下代码片段要求内部src/images/（或图像所在的任何位置）下的所有文件main.js：

// load assets
function requireAll(r) { r.keys().forEach(r); }
requireAll(require.context('src/images/', true));

这将使 Webpack 处理位于该文件夹内的所有文件。
