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'] } } })] }, -
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 } } } -
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 -
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-pluginwebpack.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) } -
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 }, -
更新一些插件
npm i -D compression-webpack-plugin@latest friendly-errors-webpack-plugin@latest optimize-css-assets-webpack-plugin@latest -
配置mode webpack.base.conf.js module.exports中：
mode: process.env.NODE_ENV === 'production' ? 'production' : 'development', -
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！！！ }), -
