Question

我对Webpack 4还是陌生的，并且努力地弄清楚为什么我不能提供CSS文件。我基本上是使用以下命令启动我的开发服务器 npm start 然后，我可以使用 http://localhost:9000/js/app.bundle.js 但是当我尝试对我的css文件执行相同操作时，它会显示404 http://localhost:9000/css/app.css

我的完整配置是

const path = require('path');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const CopyPlugin = require('copy-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');

module.exports = {
  mode:  'development',
  entry: {
    app: ['./src/js/main.js','./src/scss/style.scss'],
    admin: ['./src/js/admin.js', './src/scss/admin.scss']

  },
  output: {
    filename: 'js/[name].bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  module: {
    rules: [

      {
        test: /\.(sa|sc|c)ss$/,
        use: [
            MiniCssExtractPlugin.loader,
          {
          loader: 'css-loader',
          },
          {
            loader: 'postcss-loader',
            options: {
              plugins: function () {
                return [
                  require('autoprefixer')
                ];
              }
            }
          },
          {
          loader: 'sass-loader',
          }
        ]
      },
      {
        test: /\.(svg|jpg|png|gif)$/,
        use: {
          loader: 'file-loader',
          options: {
            name: 'assets/img/[name].[ext]',
          }
        }
      },
      {
        test: /\.(woff|woff2|eot|ttf|otf)$/,
        use: {
          loader: 'url-loader',
          options: {
            name: 'assets/fonts/[name].[ext]',
          }
        }
      },
    ],
  },

  plugins: [
    new CleanWebpackPlugin(),
    new MiniCssExtractPlugin({
      filename: "/css/[name].css",
    }),
    new CopyPlugin([
      {from: './src/img', to: 'img'},
      {from: './src/icon', to: 'icon'},
      {from: './src/fonts', to: 'fonts'},
    ]),
  ],
  devServer: {
    contentBase: path.resolve(__dirname, 'dist'),
    port: 9000
  },
};

当我运行npm run build时，我在正确的子目录中看到文件即

/dist/css/app.css
/dist/css/admin.css
/dist/js/app.bundle.js
/dist/js/admin.bundle.js

如果我将CleanWebpackPlugin()移出npm run build，则npm start将提供文件，但是我不明白为什么当它在内存中运行时它不能提供此服务。

它也可以进行以下更改

new MiniCssExtractPlugin({
      filename: "/css/[name].css",  Remove this
      filename: "[name].css"  Add this
    }),

但是我没有得到想要的子目录结构。

看来我所拥有的一切都还可以，我只需要删除/

例如

new MiniCssExtractPlugin({
      filename: "/css/[name].css",  replace this line
      filename: "css/[name].css"  with this line
    }),

Webpack不提供CSS文件
