If you see this, just know that it’s most likely related to Jest watching every files inside your node_modules directory.

Add this to your jest config:

{
    "modulePathIgnorePatterns": [
      "node_modules"
    ]
  }

And then kill all node process currrently running killall -9 node.

It should fix the problem.

I also faced this issue. And the issue was with the name of my Project.

The Project Name should not have any space in it. Once, I changed the name of the project it worked perfectly for me.
