在Ember中，我如何访问在我的初始化器中定义的自定义inflector？

import Inflector from 'ember-inflector';

export function initialize(application) {
  const inflector = Inflector.inflector;

  inflector.irregular('person', 'people');
  inflector.uncountable('sheep');
}

export default {
  initialize
};

export function initialize(application) {
  const inflector = Inflector.inflector;

  inflector.irregular('person', 'people');
  inflector.uncountable('sheep');

  application.register('custom-inflector:main', inflector, { instantiate: false });
  application.inject('route', 'customInflector', 'custom-inflector:main');
}

import Route from '@ember/routing/route';
import { inject as service } from '@ember/service';

export default Route.extend({
  customInflector: service('custom-inflector'),

  model() {
    const inflector = this.get('customInflector');
    const plural = inflector.pluralize('person');
    const singular = inflector.singularize('people');

    console.log(plural);   // 输出 'people'
    console.log(singular); // 输出 'person'
  }
});
