webpack构建的环境
1.找到build下的webpack.dev.conf.js文件
new HtmlWebpackPlugin({filename: 'index.html',template: 'index.html',inject: true,favicon: path.resolve('favicon.ico') //新增})
2.找到build下的webpack.prod.conf.js文件
new HtmlWebpackPlugin({filename: config.build.index,template: 'index.html',inject: true,favicon: path.resolve('favicon.ico'), //新增minify: {removeComments: true,collapseWhitespace: true,removeAttributeQuotes: true},
3.修改配置文件后需重启npm run dev
4.打包后根目录下就会有favicon.ico
