const EmberApp = require('ember-cli/lib/broccoli/ember-app');

module.exports = function(defaults) {
  let app = new EmberApp(defaults, {

Ah, looks like you are on an older Node version. I would recommend the current Node LTS release, which is 8.x.

(Some ember-cli versions may show a warning on that node version, but it's just paranoia, they work fine.)

That was the issue. Thanks

We should probably document. I don't think it should be too weird to require node 8, but lots of stuff in ember-cli land lags a bit on its recommendations.

@bmx269 I'm doing some issue gardening 🌱🌿 🌷 and came upon this issue. Since it's quite old I just wanted to ask if this is still relevant? If it isn't, maybe we can close this issue?

By closing some old issues we reduce the list of open issues to a more manageable set.
