Can't get it to run at all

No errors, just this.toast / self.toast undefined.

ember-cli: 2.11.1
node: 6.10.0
os: linux x64

Services are lazy, so you need to use get to use them.

var toast = this.get('toast');
// use toast

I have this problem, too. but this.get('toast') is undefined (I'm using module unification, though), not sure how much that would play in to things.

Sounds module unification related, since it's still pre alpha 👍

sorta,
I did manage to get things working by having this for my resolver.js

import Resolver from 'ember-resolver/resolvers/fallback';
// import Resolver from 'ember-resolver/resolvers/glimmer-wrapper';

import { merge } from '@ember/polyfills';

import buildResolverConfig from 'ember-resolver/ember-config';
import config from '../config/environment';

let moduleConfig = buildResolverConfig(config.modulePrefix);
/*
 * If your application has custom types and collections, modify moduleConfig here
 * to add support for them.
 */

 merge(moduleConfig.types, {
  config: { definitiveCollection: 'main' },
  locale: { definitiveCollection: 'main'},
  'ember-i18n@config': { definitiveCollection: 'main' },
  'util': { definitiveCollection: 'utils' }
});

moduleConfig.collections.main.types.push('config');

export default Resolver.extend({
  config: moduleConfig
});

I have other stuff in here in an attempt to get ember-i18n working... but there is no hope of that atm.
the main thing for ember-toastr was the config: { definitiveCollection: 'main' }

both ember, and ember-resolver need to expose a config api so that addons can add to the config in a safe way (the existing way is kind of intimate / hacky.
see: emberjs/ember.js#16373

Ember addons need an API that allows them to alter the module unification config (for example https://github.com/ember-cli/ember-resolver/blob/master/mu-trees/addon/ember-config.js) and add their own collections and types. In theory Ember (or the resolver?) would use this same API to add its own types and collections.
