Errors with Grunt Watch

[emagnier]

I'm using [email protected], [email protected] and [email protected] on Mac OS X 10.9 (and the notification center).

When making grunt watch I get this error:

Running "watch" task
Waiting...

fs.js:427
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

I'm also using Sails.js, and when it load the "watch" task (via the sails lift command) I also get an error:

I'm not sure if these errors come from the notify or the watch task. In the error messages there is a couple mentions of grunt-notify, but if I downgrade the watch plugin to 0.4.4 the problem disappears...

I was also having the same issue and downgrading grunt-contrib-watch to 0.4.4 fixed it.

I also removed grunt-notify completely, used the latest grunt-contrib-watch (master) and still had issues:

Running "watch" task
Waiting...
>> File "src/app/fooBar.js" changed.
Fatal error: spawn EMFILE

I think this is a bug with grunt-contrib-watch
