events.js:288 Error: write EPIPE when executing tests with Jest

I have a problem when setting React Testing Library into a new project, which is a project that generates common UI components for several projects. In one of the projects it is correctly setup, but when I added React Testing Library and updated dependencies in this project, I am able to run a test but not all of them.

If I do yarn test this is the result:

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
      ^

I tried doing rm -rf node_modules and then cleaning cache, and didn't work.

Any help?

In my case was the version of node. I had the version 15 (from Latest Features) and changed it to the stable version 14.17.3 (from LTS).

To know which version you have use node -v in a terminal.

By doing yarn cache clean solved my problem. If you met pipe error similar like image below. I believe it is related to memory leaks.

It turns out that by changing some libraries in package.json the error dissapears:

Before (KO):

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

After (OK):

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