vue-cli2项目-webpack3升级至4版本-报错解决详情记录

  1. 更新4.x版本webpack，并升级相关插件

     npm i -D webpack@latest
 npm i -D webpack-bundle-analyzer@latest webpack-merge@latest webpack-dev-server@latest

  2. UglifyJsPlugin报错—>webpack4.x写法改变
    报错：

    D:\workspace\zy-evst-platform\node_modules\webpack\lib\webpack.js:189
                        throw new RemovedPluginError(errorMessage);
                        ^

Error: webpack.optimize.UglifyJsPlugin has been removed, please use config.optimization.minimize instead.
    at Object.get [as UglifyJsPlugin] (D:\workspace\zy-evst-platform\node_modules\webpack\lib\webpack.js:189:10)
    .......

    解决： 修改为下面这种形式

    optimization: {
   minimizer: [new UglifyJsPlugin({
     uglifyOptions: {
       warnings: false,
       mangle: true,
       compress: {
         pure_funcs: ['console.log']
       }
     }
   })]
 },

  3. CommonsChunkPlugin 报错 —>webpack4 移除了 CommonsChunkPlugin，需要修改配置
    报错：

    D:\workspace\zy-evst-platform\node_modules\webpack\lib\webpack.js:189
                        throw new RemovedPluginError(errorMessage);
                        ^

Error: webpack.optimize.CommonsChunkPlugin has been removed, please use config.optimization.splitChunks instead.

    解决： 修改为下面这种形式（optimization中添加）

    splitChunks: {
      cacheGroups: {
        commons: {
          name: "commons",
          chunks: "initial",
          minChunks: 2
        }
      }
    }

  4. HtmlWebpackPlugin报错 —>需要升级
    报错：

    - building for production...D:\workspace\zy-evst-platform\node_modules\html-webpack-plugin\lib\compiler.js:81
        var outputName = compilation.mainTemplate.applyPluginsWaterfall('asset-path', outputOptions.filename, {
                                                  ^

TypeError: compilation.mainTemplate.applyPluginsWaterfall is not a function
    at D:\workspace\zy-evst-platform\node_modules\?[4mhtml-webpack-plugin?[24m\lib\compiler.js:81:51
    at D:\workspace\zy-evst-platform\node_modules\?[4mwebpack?[24m\lib\Compiler.js:343:11

    解决：

    npm i -D html-webpack-plugin@latest

  5. ExtractTextPlugin —> 使用mini-css-extract-plugin来替换extract-text-webpack-plugin
    报错：

    Error: Chunk.entrypoints: Use Chunks.groupsIterable and filter by instanceof Entrypoint instead
    at Chunk.get (D:\workspace\zy-evst-platform\node_modules\?[4mwebpack?[24m\lib\Chunk.js:866:9)
    at D:\workspace\zy-evst-platform\node_modules\?[4mextract-text-webpack-plugin?[24m\dist\index.js:176:48

    解决：注意有两个配置文件需要修改, 并且别忘了删除extract-text-webpack-plugin相关的配置哦

    npm i -D mini-css-extract-plugin

    webpack.conf.js中：

    const MiniCssExtractPlugin = require('mini-css-extract-plugin')

plugins: [
    new MiniCssExtractPlugin({
      filename: utils.assetsPath('css/[name].css'),
      chunkFilename: utils.assetsPath('css/[name].[contenthash].css')
   })
]

    build/utils.js
    修改前的报错：

    ERROR in ./src/assets/css/global.scss
Module build failed (from ./node_modules/extract-text-webpack-plugin/dist/loader.js):
Error: "extract-text-webpack-plugin" loader is used without the corresponding plugin, refer to https://github.com/webpack/extract-text-webpack-plugin for the usage example
    at Object.pitch (D:\workspace\zy-evst-platform\node_modules\extract-text-webpack-plugin\dist\loader.js:57:11)
 @ ./src/main.js 8:0-34

ERROR in ./src/assets/css/layout.scss
Module build failed (from ./node_modules/extract-text-webpack-plugin/dist/loader.js):
Error: "extract-text-webpack-plugin" loader is used without the corresponding plugin, refer to https://github.com/webpack/extract-text-webpack-plugin for the usage example
    at Object.pitch (D:\workspace\zy-evst-platform\node_modules\extract-text-webpack-plugin\dist\loader.js:57:11)
 @ ./src/main.js 9:0-34

    解决：

    const MiniCssExtractPlugin = require('mini-css-extract-plugin')

if (options.extract) {
   // 此处修改为：
     return [MiniCssExtractPlugin.loader].concat(loaders)
   } else {
     return ['vue-style-loader'].concat(loaders)
}

  6. 更新一些loader

    npm i -D vue-loader@latest vue-style-loader@latest

    又报错啦：

    You may need an additional loader to handle the result of these loaders.

    解决：****（vue-loader更新为15x版本以后，webpack.base.conf.js中配置需要改）

    const { VueLoaderPlugin } = require('vue-loader')

plugins: [
   new VueLoaderPlugin()
 ]

// 原来的注释掉

// const vueLoaderConfig = require('./vue-loader.conf')
{
    test: /\.vue$/,
    loader: 'vue-loader',
    // 这个注释掉！！
    // options: vueLoaderConfig
  },

  7. 更新一些插件

      npm i -D compression-webpack-plugin@latest friendly-errors-webpack-plugin@latest optimize-css-assets-webpack-plugin@latest

  8. 配置mode webpack.base.conf.js module.exports中：

    mode: process.env.NODE_ENV === 'production' ? 'production' : 'development',

  9. HtmlWebpackPlugin 配置需要修改
    报错：

     UnhandledPromiseRejectionWarning: Error: "dependency" is not a valid chunk sort mode

    解决：

    new HtmlWebpackPlugin({
      filename: config.build.index,
      template: 'index.html',
      inject: true,
      minify: {
        removeComments: true,
        collapseWhitespace: true,
        removeAttributeQuotes: true
      },
      // chunksSortMode: 'dependency' // 这里注释掉！！！
    }),

  10. 修改配置后的webpack.conf.js文件

    'use strict'
const path = require('path')
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')

  optimization: {

        warnings: false,
        mangle: true,
        compress: {

    // generate dist index.html with correct asset hash for caching.
    // you can customize output by editing /index.html
    // see https://github.com/ampedandwired/html-webpack-plugin
    new HtmlWebpackPlugin({

if (config.build.productionGzip) {
  const CompressionWebpackPlugin = require('compression-webpack-plugin')

if (config.build.bundleAnalyzerReport) {
  const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
  webpackConfig.plugins.push(new BundleAnalyzerPlugin())

module.exports = webpackConfig

  11. 修改后的webpack.base.conf.js文件
