macOS Sierra bug

[quantizor]

Not sure if this is Jest-specific or just a general node issue, but running jest --watch causes:

2016-11-01 15:46 node[5187] (FSEvents.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-22)

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: Error watching file for changes: EMFILE
    at exports._errnoException (util.js:1026:11)
    at FSEvent.FSWatcher._handle.onchange (fs.js:1274:11)

Since I upgraded to Sierra. Using Node 7.

Did you reinstall all node_modules, node and whatever else is part of node/jest?

So that definitely helped, yes. Now I'm just running into some other badness:

I think it's related to this #1772

[cpojer]

closing in favor of the other issue.

Had the original issue as well (FSEventStreamStart etc), facebook/react-native#9309 (comment) fixed it for me (increasing max open files and installing watchman 2.7 with brew).
