ES5：'use strict' 内的依赖项无法被 Heroku 缩小

Question

我正在尝试在 Heroku 上部署，但出现以下错误： remote: Failed to minify the code from this file: remote: ./node_modules/webhoseio/webhoseio.js:13

检查此依赖项后，我发现它使用了 ES5 'use strict'; 声明。我怎样才能让 Heroku 编译这个依赖项？

编辑：Package.json 文件 { "name": "stocks-app", "version": "1.0.0", "description": "Mern Demo", "main": "server.js", "scripts": { "start": "if-env NODE_ENV=production && npm run start:prod || npm run start:dev", "start:prod": "babel-node server.js", "start:dev": "concurrently \"nodemon --ignore 'client/*'\" \"npm run client\"", "client": "cd client && npm run start", "install": "cd client && yarn install", "build": "cd client && npm run build", "heroku-postbuild": "npm run build" }, "author": "", "license": "ISC", "devDependencies": { "babel": "^6.23.0", "babel-cli": "^6.26.0", "babel-preset-env": "^1.7.0", "concurrently": "^4.1.0", "nodemon": "^1.18.9" }, "dependencies": { "alphavantage": "^1.2.0", "axios": "^0.18.0", "brain.js": "^1.6.0", "cors": "^2.8.5", "dotenv": "^6.2.0", "express": "^4.16.3", "if-env": "^1.0.4", "mdbreact": "^4.8.5-patch.1", "mongoose": "^5.4.0", "newsapi": "^2.4.0", "request": "^2.88.0", "webhoseio": "^1.0.2" } }

我通过在我的 Webpack 配置中关闭缩小来解决这个问题。我没有使用 CRA 预配置的 Webpack ES-Lint 加载器，而是安装了 HTML-Loader 并将 loader 设置为它。接下来，我将最小化设置为 false。方法如下：

module: {
rules: [
  {
    use: [
      {
        options: {
          formatter: eslintFormatter,
          eslintPath: require.resolve('eslint'),
          minimize: false,
        },
        loader: require.resolve('html-loader'),
      },
    ],}}
