reactjs - 事件.js :288 Error: write EPIPE when executing tests with Jest

Question

我在将 React 测试库设置到一个新项目时遇到问题，该项目是为多个项目生成通用 UI 组件的项目。在其中一个项目中，它已正确设置，但是当我在该项目中添加 React 测试库和更新依赖项时，我能够运行测试，但不能运行所有测试。

如果我这样做 yarn test这是结果:

Test Suites: 8 passed, 8 of 33 total
Tests:       84 passed, 84 total
Snapshots:   0 total
Time:        28 sevents.js:288
      throw er; // Unhandled 'error' event
      ^

我试着做 rm -rf node_modules然后清理缓存，没有用。

有什么帮助吗？

事实证明，通过更改 package.json 中的一些库错误消失:

之前(KO):

"babel-jest": "^24.9.0",
"jest": "^26.0.1",

之后(确定):

"babel-jest": "^26.0.1",
"jest": "^25.5.4",
