Question

我正在构建使用ES6导入的Nodejs应用程序（特别是不和谐的bot），因此我使用Babel生成了生产版本。这些是命令：

"build": "rimraf dist && babel . -d dist",
"dev": "cross-env NODE_ENV=development nodemon --exec babel-node bot.js",
"start": "npm run build && node dist/bot.js",

我在本地运行npm start，一切正常。但是，此错误在部署期间不断弹出：

如果有人想看看，这是我的babel配置：

module.exports = {
  presets: [
    [
      '@babel/preset-env',
      {
        targets: {
          node: 'current',
        },
      },
    ],
  ],
  plugins: [
    [
      'babel-plugin-module-resolver',
      {
        root: ['.'],
        alias: {
          '@swifty-bot': './src',
        },
      },
    ],
  ],
  ignore: ['node_modules', 'babel.config.js'], // Ignoring itself, otherwise it will get compiled
};

我还尝试使用外部依赖项（无效）和babel本身（未编译为commonjs模块）删除严格模式。我被卡住了，不确定该怎么办。感谢您调查

Heroku部署失败-在严格模式下不允许使用旧八进制文字
