babel-loader未进行转码；没错

Question

我正在尝试让babel-loader将ES6转换为ES5，但事实并非如此。没有错误，只有ES6进入浏览器。

我在此处搜索了Stack Overflow，但没有一个答案对我有用。

webpack配置的相关部分：

const config = {
  entry: {
    app: "./src/app.js",
    editorComponents: "./src/editor-components.js"
  },
  devtool: "#source-map",
  output: {
    path: path.resolve(process.cwd(), "assets"),
    publicPath: "/themes/custom/deeson_frontend_framework/assets/",
    filename: "[name].js",
    chunkFilename: "[id].[chunkhash].js"
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /(node_modules|bower_components)/,
        use: {
          loader: "babel-loader",
          options: {
            presets: ["env"]
          }
        }
      }
    ]
  }
};

和package.json

"babel-loader": "^7.1.2",
"babel-preset-env": "^1.3.2",
"babel-core": "^6.26.3"
