Node.js 从Babel 6迁移到7导出默认值未定义

我的任务是将回购协议从babel 6迁移到7

巴别塔6

。巴别塔LRC

：

{
  "presets": [ "es2015", "stage-3" ],
  "plugins": [
    "transform-runtime",
    "transform-decorators-legacy",
    "transform-object-rest-spread",
    "transform-class-properties",
    ["module-resolver", {
      "root": ["./src"]
    }]
  ] 
}

  "presets": [["@babel/preset-env", {

    "@babel/plugin-proposal-class-properties",
    ["module-resolver", {
      "root": ["./src"]
    }]
  ]
}

Babel 7

。babelrc

：

{
  "presets": [ "es2015", "stage-3" ],
  "plugins": [
    "transform-runtime",
    "transform-decorators-legacy",
    "transform-object-rest-spread",
    "transform-class-properties",
    ["module-resolver", {
      "root": ["./src"]
    }]
  ] 
}

{
  "presets": [["@babel/preset-env", {
    "targets": {
      "node": "current"
    }
  }]],
  "plugins": [
    "@babel/plugin-transform-runtime",
    "@babel/plugin-proposal-class-properties",
    ["module-resolver", {
      "root": ["./src"]
    }]
  ]
}

有趣的是当我

nodemon--exec babel节点时。

似乎我的大多数默认导出都是

未定义的

项目结构如下：

- src
   - models
   - controllers
   - ...etc

/src/models/index.js

导入一组模型，添加

续集

关系等，然后导出，例如：

// models/index.js
import ExampleModel from 'models/ExampleModel';
import OtherModel from 'models/OtherModel';

//...

ExampleModel.belongsTo(OtherModel, { as: 'other_model' });

// ...

export {
  ExampleModel,
  OtherModel
}

然后，各个模型从

models/index.js

导入其他模型以进行设置：

// models/ExampleModel.js
import { OtherModel } from 'models';

const ExampleModel = db.define('ExampleModel', {
   // ...
   otherModelId: {
      type: Sequelize.BIGINT,
      references: { model: OtherModel, key: 'id' },
    },
   // ...
});

export default ExampleModel

OtherModel

设置基本相同：

    const OtherModel = db.define('OtherModel', {
      // ...
    });

    export default OtherModel;

ExampleModel

将抛出一个错误，提示：

/src/models/index.js:23
    return _OtherModel.default;
                       ^

TypeError: Cannot read property 'default' of undefined
    at Object.get [as OtherModel] (src/models/index.js:23:24)
    at Object.OtherModel (src/models/ExampleModel.js:82:28)

如果我只是从“models/OtherModel”执行常规导入

导入OtherModel一切都很完美

有没有什么插件我不知道，可以让我像这样导出导入？我试过很多东西，但都没有成功


编辑：

如果我在
models/ExampleModel
中从“models”

中执行

import*as models，我会得到：

{
   OtherModel: [Getter],
   AnotherExportedModel: [Getter],
   // ...etc
}
