(FSEvents.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-22)

When I run react-scripts test --env=jsdom it always display:

I am under macOS High Sierra 10.13.5

I have seen other issue like this but they have that with watchman that I don't use.

Thanks for help.

Solution

  • try it:

    brew install watchman

    It worked to me.
