[开发测试]vue单元测试SyntaxError: Unexpected token ‘export‘

贴上错误信息，方便搜索引擎查找类似错误

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:
     ? 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:

    D:\学习\vue3-pro\h5-editor\node_modules\_lodash-es@4.17.21@lodash-es\lodash.js:10
    export { default as add } from './add.js';

    SyntaxError: Unexpected token 'export'

解决方案

网上查了好久，最终找到唯一一种可以解决我的问题的方法，如果网上普遍的方法没用的朋友可以试试

参考地址：Jest setup “SyntaxError: Unexpected token export”

根据问题回复，可以在jest.config.js中进行如下配置

"transformIgnorePatterns": [
  "<rootDir>/node_modules/(?!lodash-es)"
]
