CleanWebpackPlugin在Webpack 5中未清理

我正在使用最新版本的webpack 5.3.2和“clean webpack plugin”：“^3.0.0”。显然，当我构建时，插件不会清理dist文件夹

这是我的网页信息：

  Binaries:
    Node: 12.18.1 - ~/.nvm/versions/node/v12.18.1/bin/node
    Yarn: 1.22.4 - ~/.nvm/versions/node/v12.18.1/bin/yarn
    npm: 6.14.8 - ~/.nvm/versions/node/v12.18.1/bin/npm
  Browsers:
    Chrome: 86.0.4240.111
    Firefox: 82.0
  Packages:
    clean-webpack-plugin: ^3.0.0 => 3.0.0 
    copy-webpack-plugin: ^6.2.1 => 6.2.1 
    terser-webpack-plugin: ^5.0.3 => 5.0.3 
    webpack: ^5.3.2 => 5.3.2 
    webpack-cli: ^4.1.0 => 4.1.0 
  Global Packages:
    webpack-cli: 4.1.0
    webpack: 5.3.2

这是我的网页配置：

const path = require('path');
const webpack = require('webpack');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const CopyPlugin = require('copy-webpack-plugin');

module.exports = {
  mode: 'development',
  entry: './src/index.ts',
  plugins: [
    new CleanWebpackPlugin({
  cleanOnceBeforeBuildPatterns: [path.join(__dirname, 'dist/**/*')]
}),
    new webpack.ProgressPlugin(),
    new CopyPlugin({
      patterns: [
        { from: 'src', to: 'src' },
        { from: 'package.json' },
        { from: 'README.md' }
      ],
    }),
  ],
  output: {
    filename: 'utils.min.js'
  },
  module: {
    rules: [
      {
        test: /\.(ts|tsx)$/,
        loader: 'ts-loader',
        include: [path.resolve(__dirname, 'src')],
        exclude: [/node_modules/]
      },
      {
        test: /\.m?js$/,
        exclude: [/node_modules/],
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env']
          }
        }
      }]
  },

  resolve: {
    extensions: ['.tsx', '.ts', '.js']
  }
}

 output: {
    filename: 'utils.min.js',
    clean: true,
 }

即使启用详细选项，我也看不到日志，插件也不会清理。

显然，当您指定一个选项时。输出（在我自定义输出包名称的情况下）

clean webpack plugin

也需要您指定路径，否则插件将被禁用，不会出现错误！：

  output: {
    filename: 'utils.min.js',
    path: path.resolve(__dirname, 'dist')
  },

---

从webpack v5中，您可以删除

clean webpack插件

插件，并在您的webpack配置中使用output.clean选项：

const path = require('path');
const webpack = require('webpack');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const CopyPlugin = require('copy-webpack-plugin');

module.exports = {
  mode: 'development',
  entry: './src/index.ts',
  plugins: [
    new CleanWebpackPlugin({
  cleanOnceBeforeBuildPatterns: [path.join(__dirname, 'dist/**/*')]
}),
    new webpack.ProgressPlugin(),
    new CopyPlugin({
      patterns: [
        { from: 'src', to: 'src' },
        { from: 'package.json' },
        { from: 'README.md' }
      ],
    }),
  ],
  output: {
    filename: 'utils.min.js'
  },
  module: {
    rules: [
      {
        test: /\.(ts|tsx)$/,
        loader: 'ts-loader',
        include: [path.resolve(__dirname, 'src')],
        exclude: [/node_modules/]
      },
      {
        test: /\.m?js$/,
        exclude: [/node_modules/],
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env']
          }
        }
      }]
  },

  resolve: {
    extensions: ['.tsx', '.ts', '.js']
  }
}

 output: {
    filename: 'utils.min.js',
    clean: true,
 }
