ember.js - Could not find module `ember-infinity/mixins/route` -

i trying implement infinite-scrolling using ember-infinity. have followed documentation getting error "could not find module ember-infinity/mixins/route" below code

import ember 'ember'; import infinityroute 'ember-infinity/mixins/route';  export default ember.route.extend(infinityroute,{ store: ember.inject.service(),  model(){     var inflector = ember.inflector.inflector;      inflector.irregular('feed', 'feeds.php');     inflector.uncountable('advice');     let user = json.parse(localstorage.getitem('user'));     let token = localstorage.getitem('token');     if(user != null){         //return this.get('store').query('feed',{page:1,userid:user.id,token:token});         return this.infinitymodel("feed", { perpage: 12, startingpage: 1,userid:user.id,token:token });     } } , actions:{   getdetails(feed){     console.log("getting details of "+feed.id);   } } }); 

could please tell me causing error or tutorial can teach infinite-scrolling using ember js?

don't forget restart ember-cli after install it.
