Application freezes during 'compileCoffeescript'

Question

I have a meteorite app that has really weird behavior. Usually it freezes only at startup and recording:

sercan@home:~/meteor_work/***$ meteor
[[[[[ ~/meteor_work/mongoclient ]]]]]         

=> Started proxy.                             
=> Started MongoDB.                           
   Loading plugin 'compileCoffeescript' ...  -

What could be the problem here? Any help would be appreciated.

ps meteor version 1.2.1

Thank you in advance

UPDATE: After deleting a line coffeescript@1.0.11from the version file, it went through the compilation phase and now gets stuck:

Building for web.browser                  -

UPDATE2: I read this problem and decided to comment below on ecmascript dependency:

#ecmascript              # Enable ECMAScript2015+ syntax in app code

Then it worked !!! But now I can not use ECMAScript2015 +, etc., Of course, in any case, I do not need it. But I need a very brief explanation about this ...
