"Native thread-sleep not available." when gulp images

[angusjune]

Terminal warning:
"Native thread-sleep not available.
This will result in much slower performance.
You should re-install spawn-sync if possible."
And the images won't be copied to directory app.

Tried to re-install spawn-sync, but didn't fix the problem.

I'm in same problem and found how to remove the warning.

npm list

would shows you need "try-thread-sleep" to use spawn-sync.

So, add bellow in your "package.json" and "npm install" again.

"try-thread-sleep": "^1.0.0",

Solved after installing try-thread-sleep

@TatsuyaHishima and @rizqinizamil thanks for you inputs. I ran the npm list and it clearly indicated the error
npm ERR! missing: try-thread-sleep@^1.0.0, required by spawn-sync@1.0.13 npm ERR! missing: try-thread-sleep@^1.0.0, required by spawn-sync@1.0.11 npm ERR! not ok code 0
I installed try-thread-sleep and the error went away.

For anyone that runs into this in future, the resolution is:

1. Upgrade to node@0.12 or node 4
2. Install try-thread-sleep as a dependency of your app directly.

It should no longer be an issue in master.
