Question

我的第一个＆＃34; Hello Webpack＆＃34;项目进展顺利，直到我开始整合CleanWebpackPlugin。如果我手动删除我的/ dist文件夹然后构建，则此配置有效。但是如果/ dist文件夹存在且example按其设计删除它，则PurifyCSS会抛出此错误：

clean-webpack-plugin：\ dist已被删除 purifycss-webpack \ dist \ index.js：52 \ if（！_fs2.default.existsSync（p））抛出新错误（＆＃39;路径＆＃39; + p +＆＃39;不存在。＆＃39;）;

是否有其他方法让Webpack仅在所有其他插件执行后运行PurifyCSS？我认为我是通过将它放在插件数组中的最后一个来做到这一点，但这感觉就像执行顺序问题给我。这是我的配置：

const CleanWebpackPlugin = require('clean-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const globAll = require('glob-all');
const HtmlWebpackPlugin = require("html-webpack-plugin");
const path = require("path");
const PurifyCSSPlugin = require('purifycss-webpack');
const webpack = require("webpack");

var extractPluginCSS = new ExtractTextPlugin({
  filename: "app.css"
});

module.exports = {
  entry: "./src/js/app.js",

  output: {
    path: path.resolve(__dirname, "dist"),
    filename: "app.js"
  },

  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: [
          {
            loader: "babel-loader",
            options: {
              presets: ["env"]
            }
          }
        ]
      },

      {
        test: /app\.scss$/,
        use: extractPluginCSS.extract({
          use: [
            {
              loader: "css-loader",
              options: {}
            },
            {
              loader: "sass-loader",
              options: {}
            }
          ]
        })
      },

      {
        test: /\.html$/,
        use: ["html-loader"]
      },

      {
        test: /\.(jpg|png)$/,
        use: [
          {
            loader: "file-loader",
            options: {
              name: "[name].[ext]",
              outputPath: "img/"
            }
          }
        ]
      }

    ]
  },

  plugins: [

    new CleanWebpackPlugin(['dist']),

    new HtmlWebpackPlugin({
      template: "./src/html/index.html"
    }),

    new webpack.optimize.UglifyJsPlugin(),

    extractPluginCSS,

    new PurifyCSSPlugin({
      // Give paths to parse for rules. These should be absolute!
      paths: globAll.sync([
        path.join(__dirname, '/dist/*.html')
      ]),
      // minimize: true,
      verbose: true
    })

  ]

};

是否可以强制PurifyCss插件等待捆绑包准备好？
