我正在对目前没有测试的现有项目进行测试.我的测试无法编译node_modules/导入.

/Users/me/myproject/node_modules/lodash-es/lodash.js:10
export { default as add } from './add.js';
^^^^^^
SyntaxError: Unexpected token export

  at transformAndBuildScript (node_modules/jest-runtime/build/transform.js:320:12)
  at Object.<anonymous> (app/reducers/kind_reducer.js:2:43)
  at Object.<anonymous> (app/reducers/index.js:12:47)

我发现的解决方法是node_modules在package.json jest配置中'whitelist' ,如下所示:

"jest": {
    "transformIgnorePatterns": [
      "!node_modules/"
    ]
  }

这似乎是一个黑客,因为它需要超过1分钟来运行一个简单的导入测试node_modules/lodash-es/lodash.js.

感谢任何帮助或方向,谢谢!

我突然得到这个错误。

代码在我使用时工作正常，但在使用Jest测试时会弹出此问题。...................................................... ...................................................... ...................................................... ...................................................... ...................................................... ...................................................... ...................................................... ...................................................... ......

这是我的笑话配置

module.exports = {
  moduleNameMapper: {
    // Resolve .css and similar files to identity-obj-proxy instead.
    '.+\\.(css|styl|less|sass|scss)$': 'identity-obj-proxy',
