webpack4,Babel传输到ES5和uglifyjs Webpack插件的困境

我在尝试运行我的网页包生成时出错。

node_modules/webpack/bin/webpack.js -p --config webpack.config.production.js

...

ERROR in app.js from UglifyJs
Unexpected token: keyword (const) [app.js:18757,0]

...

通过查看这个错误,我了解到这可能会导致ES6代码进入系统 uglifyjs-webpack-plugin

但是如果我有babel设置将代码传输到es5中,为什么会这样呢?

巴别塔

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "targets": {
          "node": "6.10",
          "esmodules": true
        }
      }
    ]
  ],
  "plugins": ["@babel/plugin-proposal-object-rest-spread"]
}

网页包公共配置

module.exports = (env, options) => ({
  ...
  module: {
    rules: [
      {
        test: /\.js$/,
        use: {
          loader: "babel-loader",
          options: {
            presets: ["@babel/preset-env"]
          }
        },
        exclude: /node_modules/
      },
    ...

还有我的产品配置

...
const UglifyJsPlugin = require("uglifyjs-webpack-plugin");

...
const webpackCommonConfig = require("./webpack.config.common")();

module.exports = merge(webpackCommonConfig, {
  mode: "production",
  optimization: {
    minimizer: [
      new UglifyJsPlugin({ cache: false, parallel: false, sourceMap: false }),
    ...
    ]
  }
});

我的假设是,在优化运行之前,babel会将js传输到es5中。我错过了什么?
