Trying to build with ember build fails

[fullofcaffeine]

Hi,

Thanks for this addon!

I did some small changes and wanted to build the dist myself. I assume I need to use ember build, but I get the following error (backtrace included):

~/workspace/code/ember-select-2 (master●)$ ember build                                                                                                        [2.2.1]

How should I build ember-select-2, am I missing something?

Thanks in advance.
