多个条目 + 带有 rollup 和 rollup-plugin-babel 的 preserveModules - 为什么 _rollupPluginBabelHelpers.js 中没有包含所有助手？

Question

所以我有一个 JSX 库，我正在转换它以包含在 React 项目中。

配置

rollup.config.js:-

import babel from "rollup-plugin-babel"
import pkg from "./package.json"

const externals = Object.keys(pkg.peerDependencies || {})

export default [
  {
    input: __dirname + "/src/File1.js",
    output: {
      dir: __dirname + "/lib/",
      format: "esm",
    },
    plugins: [
      babel({}),
    ],
    preserveModules: true,
    external: externals
  },
  {
    input: __dirname + "/src/File2.js",
    output: {
      dir: __dirname + "/lib/",
      format: "esm",
    },
    plugins: [
      babel({})
    ],
    preserveModules: true,
    external: externals
  },
  ...
]

.babelrc（在 /src 内）：-

{
  "presets": [
    ["@babel/preset-env", {"modules": false}],
    "@babel/preset-react"
  ],
  "plugins": [
    [
      "@babel/plugin-proposal-class-properties"
    ],
    [
      "babel-plugin-styled-components"
    ]
  ]
}

问题

当我将代码包含在我的 webpack 编译器中时，出现如下错误：-

WARNING in ./lib/File1.js 29:146-161 "export 'defineProperty' (imported as '_defineProperty') was not found in './_virtual/_rollupPluginBabelHelpers.js'

WARNING in ./lib/File2.js 45:11-25 "export 'objectSpread2' (imported as '_objectSpread2') was not found in './_virtual/_rollupPluginBabelHelpers.js'

似乎提供一个包含多个条目的数组会导致 _rollupPluginBabelHelpers.js 只填充数组中最后一个条目所需的助手。

谁能帮我解决这个问题？我已经阅读了我能找到的所有文档并用谷歌搜索，但我找不到答案。谢谢

问题已 resolved on github 以下配置：-

export default {
    input: [__dirname + "/src/File1.js", __dirname + "/src/File2.js"],
    output: {
        dir: __dirname + "/lib/",
        format: "esm",
    },
    plugins: [
        babel({}),
    ],
    external: externals
}

multiple entries + preserveModules with rollup and rollup-plugin-babel - why are all helpers not included in _rollupPluginBabelHelpers.js?
