在 webpack.prod.conf.js 中添加

代码：

plugins: [
        // http://vuejs.github.io/vue-loader/en/workflow/production.html
        new webpack.DefinePlugin({
            'process.env': env
        }),
        new UglifyJsPlugin({
            uglifyOptions: {
                compress: {
                    warnings: false,
                    //过滤console.log-start
                    drop_console: true,
                    pure_funcs: ['console.log']
                    //过滤console.log-end
                }
            },
            sourceMap: config.build.productionSourceMap,
            parallel: true
        })
        ...
 ]

如果你用的vue3：

代码：

module.exports = {
  lintOnSave: true,
  // 配置webpack打包
  configureWebpack: (config) => {
  	// 取消console打印    
    config.optimization.minimizer[0].options.terserOptions.compress.drop_console = true
    // 如果是多环境打包
    //if (process.env.NODE_ENV === 'production') {
      //config.optimization.minimizer[0].options.terserOptions.compress.drop_console = true
   // }
  },
  ...
}
