Error npm test on MacOs Sierra

Created by: manuelitox

Hey there,

I can't run with success the npm test command:

❯ npm test

> react-scripts test --env=jsdom
Determining test suites to run...2016-10-07 11:38 node[873] (FSEvents.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-22)

      throw er; // Unhandled 'error' event
      ^

npm ERR! Test failed.  See above for more details.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts: [email protected]
2. node -v: v6.7.0
3. npm -v: 3.10.3
4. Operating system: MacOs Sierra

Any idea?
