如何打印 babel 或 babel 插件转换了哪些文件？

Question

我正在编写应该转换 node_modules 之一的 babel 和 jest 配置。 目前不起作用，我想知道我得到的错误是否是因为文件没有转换。 不幸的是，我还没有找到一种方法来记录由哪个插件/预设转换的所有文件。

我正在使用下面的配置。

jest.config.js ：

module.exports = {
  "transform": {
    "\\.[jt]sx?$": "babel-jest",
  },
  transformIgnorePatterns: ["<rootDir>/node_modules/some-module"],
}

babelrc.js ：

module.exports = {
  "presets": [
    "@babel/preset-typescript",
    "@babel/preset-env",
  ],
  "plugins": [
    "@babel/plugin-transform-modules-commonjs",
  ]
}

最后，我收到与未转换的 node_modules 之一相关的错误：

  Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/en/ecmascript-modules for how to enable it.
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

    Details:

    /something/node_modules/some-module/theme/index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import * as theme from './theme';
                                                                                             ^^^^^^
