Ember.js: Pass options to node.js

I'm trying to build some LESS code (via ember-cli-less) to CSS file.

1) http://ift.tt/1F4prXX AdminLTE LESS files 2) Bootstrap LESS files.

And I got:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory

So I need to pass somehow --max_old_space_size=big_number when launch

ember build

How I can do this?
