node.js - 如何让 serverless-webpack 与 babel.v8 一起使用来解决 - 错误：插件/预设文件不允许导出对象，只能导出函数？

问题描述

什么地方出了错？

Babel 从 7.x 迁移到 8.x 节点从 8.x 迁移到 10.x

你用的是什么配置？

将 .babelrc 中的目标从 8.10 更改为 10.14.1 将 serverless.yml 中的运行时从 8.10 更改为运行时：nodejs10.14.1

您看到了来自您的提供商的哪些堆栈跟踪或错误消息？

这是我的.babelrc文件中的内容：

{
    "plugins": [],
    "presets": [
        ["env", {"node": "10.14.1"}],
        "stage-3"
    ]
}

这是我的依赖项package.json：

"devDependencies": {
    "aws-sdk": "^2.350.0",
    "babel-core": "^6.26.3",
    "babel-eslint": "^10.0.1",
    "babel-loader": "^8.0.6",
    "babel-plugin-source-map-support": "^2.0.1",
    "babel-plugin-transform-runtime": "^6.23.0",
    "babel-preset-env": "^1.7.0",
    "babel-preset-stage-3": "^6.24.1",
    "eslint": "^5.15.0",
    "eslint-config-standard": "^12.0.0",
    "eslint-plugin-import": "^2.14.0",
    "eslint-plugin-node": "^9.1.0",
    "eslint-plugin-promise": "^4.0.1",
    "eslint-plugin-react": "^7.12.4",
    "eslint-plugin-standard": "^4.0.0",
    "jest": "^24.8.0",
    "serverless-offline": "^5.0.0",
    "serverless-webpack": "^5.1.0",
    "webpack": "^4.16.2",
    "webpack-node-externals": "^1.6.0"
  },

你怎么看？如果可能的话，我真的很想保持最新状态并使用最新版本的 babel。有人知道 serverless-webpack 是否支持 babel.v8 吗？

如果是这样，考虑到上述信息，我怎样才能让他们一起工作？

谢谢！

解决方案

以防万一它有帮助，我能让它工作的唯一方法就是这样评论babel-loader：

module: {
    rules: [
      {
        test: /\.js$/,
        // TODO: This was the fix to sls deploy
        // loader: "babel-loader",
        include: __dirname,
        exclude: /node_modules/
      }
    ]
  }

不确定这是否是最好的解决方法，但它帮助我解决了我正在处理的当前问题。
