javascript - 如何正确配置 babel 以使用 lodash-es？

Question

我需要在我的项目中使用lodash-es，但是我无法正确配置我的babel，它总是报错，比如SyntaxError: Unexpected identifier

hello.js

import upperCase from 'lodash-es/upperCase'

console.log(upperCase('lodash-es'));

package.json

{
  "scripts": {
    "demo": "babel-node hello"
  },
  "devDependencies": {
    "@babel/cli": "^7.0.0",
    "@babel/core": "^7.0.0",
    "@babel/node": "^7.0.0",
    "@babel/preset-env": "^7.0.0"
  },
  "dependencies": {
    "lodash-es": "4.17.11"
  }
}

.babelrc

{
  "presets": [
    "@babel/preset-env"
  ]
}

当运行 babel-node hello 时，报如下错误:

> /javascript-babel-node-use-lodash-es-issue-demo
> babel-node hello

(function (exports, require, module, __filename, __dirname) { import createCompounder from './_createCompounder.js';
                                                                     ^^^^^^^^^^^^^^^^

SyntaxError: Unexpected identifier

    at createScript (vm.js:251:10)
    at Object.runInThisContext (vm.js:303:10)

我也针对这个问题设置了一个小demo，有需要的可以克隆试试:https://github.com/freewind-demos/javascript-babel-node-use-lodash-es-issue-demo

require("@babel/register")({
    ignore: [/node_modules\/(?!lodash-es)/],
});
