Reactjs 测试套装失败，带有“0”；SyntaxError:意外标记'；“出口”'；使用笑话来反应类型脚本

我在react typescript项目中设置了jest和Ezyme。在这个项目中，我没有使用巴贝尔

我试着运行基本组件，它工作得很好

之后，我添加了另一个组件，并在这个组件中添加了自定义的基于react-typescript的库（cc-react-common库）

当我包含cc react公共库时，jest抛出以下错误

语法错误：意外标记“导出”

 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:
     • 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:

    /home/convertcart/projects/intelli-blocks/node_modules/cc-react-common-lib/lib/index.js:1
    export { default as TableSpaced } from './general/table-spaced';
    ^^^^^^

    SyntaxError: Unexpected token 'export'

我试图在过去的一周内解决这个错误，但我找不到任何解决方案

jest.config.js：

module.exports = {
  // The root of your source code, typically /src
  // `<rootDir>` is a token Jest substitutes
  roots: ['<rootDir>'],

  // Jest transformations -- this adds support for TypeScript
  // using ts-jest
  // transform: {
  //   "^.+\\.tsx?$": "ts-jest"
  // },
  preset: 'ts-jest',
  // maxConcurrency:30,
  // Runs special logic, such as cleaning up components
  // when using React Testing Library and adds special
  // extended assertions to Jest
  // setupFilesAfterEnv: [
  //   "@testing-library/react/cleanup-after-each",
  //   "@testing-library/jest-dom/extend-expect"
  // ],

  // Test spec file resolution pattern
  // Matches parent folder `__tests__` and filename
  // should contain `test` or `spec`.
  testRegex: '(/__tests__/.*|(\\.|/)(test|spec))\\.tsx?$',

  // Module file extensions for importing
  moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
  snapshotSerializers: ['enzyme-to-json/serializer'],
  setupFilesAfterEnv: ['<rootDir>/setupEnzyme.ts'],
};

更新：当我在jest.confi.js文件中添加以下行时

transform: {
    '^.+\\.tsx?$': 'babel-jest',
  },

出现以下错误消息：

    Add @babel/preset-react (https://git.io/JfeDR) to the 'presets' section of your Babel config to enable transformation.
    If you want to leave it as-is, add @babel/plugin-syntax-jsx (https://git.io/vb4yA) to the 'plugins' section to enable parsing.

Jest 25应该有本机ESM支持这是否回答了您的问题？@DenisTsoi感谢您的评论。这个答案没有帮助。我更新了我的问题，请检查
