Error broccoli-esnext is deprecated. in http://ift.tt/1P7RIN0

Running examples from http://ift.tt/1P7RIN0 . I'm receiving errors :

:~/ember-projects/emberjs-essentials/chapter-5/example1$ ember server

version: 0.1.4 invalid watchman found, version: [4.3.0] did not satisfy [^3.0.0], falling back to NodeWatcher [deprecated] broccoli-esnext is deprecated. Use broccoli-babel-transpiler instead. http://ift.tt/1AQUhie [deprecated] broccoli-esnext is deprecated. Use broccoli-babel-transpiler instead. http://ift.tt/1AQUhie [deprecated] broccoli-esnext is deprecated. Use broccoli-babel-transpiler instead. http://ift.tt/1AQUhie [deprecated] broccoli-esnext is deprecated. Use broccoli-babel-transpiler instead. http://ift.tt/1AQUhie

and then ember server won't work properly. It starts but I never receive response from localhost:4200 keeping waiting for it. I checked code for existing references to broccoli-esnext. But it seemed to be called as the dependence not included directly in package.json. Can someone please explain how to fix this. Spent lots of time googling the issue but with no luck so far.
