Issues when running "ember generate ember-mu-application-generator"

[asjongers]

When adding the generator to a new project (using Ember-cli 3.1.4), I run into the following issue:

updating router
  add route route-not-found
  install package jquery-datetimepicker
  install addon ember-power-select
  install addon ember-datetimepicker
  install addon ember-changeset
Command failed: npm install --save-dev --loglevel error ember-changeset

I then tried to install the needed dependencies manually running:

ember install ember-power-select
ember install ember-changeset
ember install ember-datetimepicker

But it would complain about a missing npm package (the generator):

Missing npm packages: 
Package: ember-mu-application-generator
  * Specified: git+https://github.com/tenforce/ember-mu-application-generator.git
  * Installed: (not installed)

Run `npm install` to install missing dependencies.



Stack Trace and Error Report: /tmp/error.dump.c8b841b57cf3b46ce087de3ab332988d.log
An error occurred in the constructor for ember-cli-dependency-checker at /home/arnaud/Documents/git/subject-pages/node_modules/ember-cli-dependency-checker

Doing npm install solved that, I could then install the needed dependencies and because running ember generate ember-mu-application-generator already installed the needed files (components and so on), I could just run "ember serve" and get something working. However, as you can imagine, this probably needs some looking into.
