Building Ember app gives me error, Cannot read property 'pkg' of null

I was trying to compile a website frontend from 2015 that utilizes an old version of ember.js and node.js. The instructions state to run make build, which in turn would run ember build dist. Though when the command is ran, it gives me this error.

Cannot read property 'pkg' of null

This error is shown even if just ember is ran in terminal.
